Fitchia mangarevensis was endemic to Tarvai in the Gambier islands of French Polynesia. It was described by science in the 20s and studied through the 50s, but hasn’t been seen since. The Gambier islands have a long history of human environmental destruction.  While the Gambier islands once had a population of thousands, they can now only support a few hundred.  Many Tarvai villages are abandoned or very small – the wikipedia article is a bit unclear, but there may only be 3 residents of the entire island.

There isn’t a lot of information about Fitchia, though research articles in the 50s suggested it could be useful for learning about vascular and floral evolution.  Considering that F. mangarevensis key to that research and at least 3 of 8 known Fitchia species are threatened, we’ll probably never be able to answer all of our questions about the evolution of this genus.

While in Davis, I did take my own advice and went to the arboretum a few times.  I was especially fascinated with a group of plants in their Australian collection that produced flowers along their stems and kept on growing – you could see what was left sheathing the stems for years afterward.

My town has an arboretum that I’m familiar with mostly because there are several ongoing forest ecology experiments nearby.  I visited the public part once the first year I was here and then again a few weeks ago when my mother was visiting.  I appreciate it a lot more now that I know so much more about the regional climate and flora.

The arboretum is quite small, but it’s got a good representation of the region’s plants and habitats and fantastic demonstration gardens for people who want to use less water and native plants. The arboretum also collaborates with ecologists and botanists at my university on some pretty sweet experiments.

I saw a horned toad for the first time when I visited the arboretum with my mom.  They blend in really well! I definitely didn’t notice it until it was pointed out to me.

Arboretums are the kind of thing that are really going to lose out as states slash funding in an attempt to make ends meet.  Visiting museums, botanic gardens, arboretums, national and state parks, etc. is often cheaper than a trip to the movies and usually much more interesting. (Has anyone noticed the near complete lack of plot in a lot of new movies?)

Erythroxylum echinodendron

Erythroxylum echinodendron

Erythroxylum echinodendron was endemic to Cuba and was declared extinct in the wild in 1998.  Echinodendron means “spiny tree,” and you can see where it got its name in this herbarium specimen.  Erythroxylum is a tropical genus with about 250 species.

While this particular species was declared extinct in the wild rather than extinct, this damaged herbarium specimen is the only record I could find of Erythroxlym echinodendron.  There don’t seem to be any reintroduction projects in place or even specimens being studied in botanical gardens.

This is particularly sad since many Erythroxylum species are hosts for butterfly and moth larvae and some have powerful alkaloid compounds. Not only are we probably losing insect species with the loss of this plant, but we’ve lost a plant that could have contained chemicals for new medications.

While you may have never heard the word “Erythroxylum,” a large number of your tax dollars are spent trying to control a particular species in this genus.  You may have even used a product of  Erythroxylum coca.

While most people wouldn’t recognize this shrub,

Welcome to the 17th edition of Berry Go Round!  Before you get started here, you may want to check out the 16th edition hosted at Quiche Moraine.  It’s full of exciting posts on mutualism.

GrannyJs knitted leaf. ID, anyone?

GrannyJ's "knitted leaf." ID, anyone?

GrannyJ’s A garland of leaves at Walking Prescott, is a beautifully illustrated post comparing the shapes and colors of a variety of leaves.  As she says, leaves are “quite as interesting as flowers, though not nearly as gaudy.”  My personal favorite of her many examples is a leaf that looks like it’s been knitted!

In addition to some garden plants, she posted quite a few shots of natives.  One of the features many of them have in common are tough, evergreen leaves.  If you want to have leaves that stick around in the desert, they should be tough, filled with some nasty chemicals, and good at conserving water.

Jeremy Yoder presents Seed dispersal by ants: A lousy way to travel, a good way to diversify posted at Denim and Tweed, saying, “Myrmecochory, or seed dispersal by ants, is an evolutionary “key innovation” that helps generate new species – not because it’s such a great way to disperse seeds, but because it actually isn’t.”

I find ant-plant mutalisms fascinating.  If you liked Jeremy’s post as much as I did, you may also be interested in this Science article about ants, Acacia, and large mammal herbivores.  Ants protect Acacia from large mammal herbivores and are rewarded with nectar. When the mammals were kept away from the plants for a number of years, the Acacia stopped providing so much nectar for the ants.  This seems like a good thing to do – why waste resources feeding the ants if you don’t need them to project you anymore?  However, the lack of nectar caused the ants to lose their competitive edge against stem boring beetles which did all kinds of damage to the trees and even caused many of them to die.

Sally at Foothills Fancies writes about a trip to Lair o’ the Bear and despite the rather scary title – Live at the Bear’s Lair – the post is full of flowers, not carnivores.  This Sand Lily is just one of the lovely wildflowers she highlights, sharing this interesting little tidbit:

In these spring plants, the ovary is below ground level, so the pollen tube has a long way to go to reach it. The seeds mature underground and later get pushed out onto the surface where they can germinate.

While it sounds like Sally had a great trip, she was disappointed at not getting any good pictures of Pasqueflowers (Pulsatilla patens). Lucky for us, Priscilla Stuckey of this lively earth presents us with both lovely photos of Pasqueflowers and their strategy for fending off snow and ice along the Front Range of Colorado in Pasqueflower’s risky business.

Janet Creamer from Midwest Native Plants, Gardens, and Wildlife has another wildflower-filled post for us – Flowers and such from Boch Hollow.  When I saw her photo of Running Buffalo Clover and learned it was endangered, I got a little nervous – wasn’t that the plant I spent half my childhood pulling out of our flower gardens? I was relieved to find out that it was not!  The weed I remembered is White Clover, which is in no way endangered.

Emily at No seeds, no fruits, no flowers: no problem shares her first field trip of the season in First ferns.

She has several stunning fern photos featured, including these Dryopteris goldiana fiddleheads.  They’re ENORMOUS and kind of look like some sort of larvae to me. Luckily, they don’t squirm and have such nice colors, so I’m not disgusted.  When I went to Lotusland last year, I was impressed with the fiddleheads on one of the ferns I saw there.  They were as large as my fist!

Martin Nuñez at The EEB and flow blogs a recent paper that shows that Artemisia tridentata recognizes itself.  How cool is that?

Last but not least, I’ve got some ID puzzles for you all!  I met David while I was teaching English in China.  He’s currently teaching in Suzhou, which is famous for its gardens.  The following photos were taken in The Lingering Garden and he wants to know what these plants are.  He didn’t get shots of the leaves or growth habit, which makes this a bit more of a challenge.

Click on any of the photos for a larger image.  Also, I highly recommend browsing the rest of David’s flickr photos – they’re wonderful!

A beautiful post on hierarchies and judgement within marginalized communities.

The Skeptic’s Book of Pooh-Pooh points out an awesome news story on the danger anti-vaxers create for children in their communities.  The anti-vaxers hypocrisy is also on display in their support of chemical castration for autistic boys.

We can’t expect toxic products to stop coming from China anytime soon.  Honesty and transparency are impossible with a government that actively represses knowledge of its own history.

Women continue to be kidnapped, sexually assaulted, and brutally murdered in Mexico.  Despite the hundreds of victims that are likely the victims of one or more serial killers, the police aren’t doing anything about it.

As the AZ legislature slashes education funding across the state, especially at the university level, the AZ Republic has a timely article about the importance of research – even if it sounds ridiculous.

It’s been quite a few weeks since I’ve featured an exinct plant, but the series isn’t dead yet!  While I really enjoy researching and sharing what I find about extinct species, it does take more time than I had at the end of the semester.

Many of the plants I feature are extinct in the wild but have a few survivors in botanical gardens and such.  I have a couple reasons for preferring to feature plants that are only extinct in the wild rather than completely extinct.  One, I like to be able to show some sort of image of the plant – even if it’s just an herbarium specimen or a drawing – and it’s much easier to find pictures of plants that have even a few living specimens.  Showing an image of the plant makes it seem more real I think – it’s harder to ignore.  The second reason is that even if a plant is extinct in the wild, as long as we have a few living specimens, it may have a chance of rebounding if we keep propagating it, planting it, and restoring its habitat.

Encephalartos nubimontanus is a cycad species that is extinct in the wild.  It was native to the Limpopo province of South Africa where it grew on the Northern Drakensberg escarpment, often on cliff faces.

I’ve written before about cycads and I’ve probably mentioned that cycads are one of my favorite kinds of plants.  Encephalartos nubimontanus is a particularly beautiful species.

Encephalartos nubimontanus

Encephalartos nubimontanus

Nubimontanus means “black mountain,” perhaps named after the black cliff faces of the region.  By the 1980s, just one population of about 66 plants remained – by 2001 that number had declined to 8 and in 2003, none.  Many of these cycads were poached and I imagine that if you bought one today it would be the child or grandchild of one of those poached specimens.  The other important factor leading to the extinction of this species was debarking for medicinal use.  Cycads produce numerous powerful chemical compounds and are incredibly toxic.

South Africa is home to numerous cycad species and many of them are on the brink of extinction because of plant poaching.  Luckily, the South African government is working to protect their endangered cycad populations.

While the native plants and animals of the western US aren’t in as much danger from poachers, they are threatened by habitat destruction and climate change.  Under rules issued by the Bush Administration, the Bureau of Land Management may lease millions of acres of land in Colorado, Utah, and Wyoming for commercial oil shale development.  Oil shale extraction, processing, and use are all very, very bad for the environment and mining laws in the West can let mining companies destroy the environment and not pay a dime. So write the BLM and tell them to set up some solar panels instead of digging up a dirty, inefficient fuel source.

Panda plant

Panda Plant, Kalanchoe tomentosa, is a close relative of Mother of Thousands.  It’s called a Panda Plant because the leaves are very very fuzzy and have red tips and they supposedly resemble panda toes.  Though both pandas and Panda Plants are very cute, I do not think there is any real resemblance.

Baby panda

Mother of Thousands can propogate rapidly with little plantlets on the edge of their leaves.  Panda Plants can also propogate from their leaves – but they only make one plantlet per leaf and they only do it if the leaf is in contact with the soil.  It’s still pretty cool, though.  When most plants lose a leaf, the leaf dies.  When a Panda Plant loses a leaf, it clones itself.

This is how my Panda Plant got started.  Mine is a bit leggier than most because it doesn’t get enough sunshine.

mother of thousands

Mother of Thousands

I promised to show you pictures of my plants a few weeks ago.  I’ve taken pictures of a few of them, but not all.  The weather has been so strange here and is making picture taking difficult.

This plant is a Mother of Thousands, a kind of Kalanchoe. It forms little plantlets on its leaves – you can see a few in this picture – and then drops them.  It’s incredible the number of little clones this plant makes in just a few months.

I started this mother of thousands from a plantlet about a year and a half ago.
