I decided to start the fern role-call with this species, a new one for me, mostly because it's got a cool name: T. qualpaertensis. The etymology of scientific names is a hobby of mine, but here I'm stumped. I have no idea what it means, as my Botanical Latin book is back home in Wisconsin while I'm here in DC. T. qualpaertensis looks like most Thelypterises I've come across, and I was particularly enchanted by its sori, which looked to me like little blackberries.

Vancouver and Beyond
This post serves as a (very brief) introduction to the types of habitats and plants I saw out there, and I'll follow it up with several entries about specific ferns I encountered.
The pictures above are from a fern foray that took place Saturday, July 27th, to the Lower Seymour Conservation Area and Mount Seymour, north of Vancouver. There are usually several field trips on the weekend preceding the Botany conference each year, and the fern ones are always the most fun (of course). On this trip we visited typical conifer forest at the Conservation area, and as you can see, there were tons of ferns. The ones most prominent in these photos are Athyrium filix-femina (Western Lady Fern) and Blechnum spicant. I'm bad at trees, so I don't know the species that were present, but suffice to say there were lots of them, and they were BIG.
The forest was pretty rich and dense with plant life, including mosses that were draped over many of the branches. Surprisingly, despite the lush coverage of ferns, the fern flora was fairly depauperate (meaning number of species, not abundance of plants). Earlier this summer I was able to locate 15 fern species on just two or three acres at my parents' home, while my list topped out at around 10 species for this incredible forest. It's likely that there just aren't a ton of ferns able to cope with the relatively low water availability imposed by the long winters in this area of the world.

Online Fern Key
Back to fern-focused posts. For anyone who lives in Wisconsin, or most of the midwest or northeast for that matter, this guide to the pteridophytes of Wisconsin is a great resource. Hosted by the Cofrin Center for Biodiversity at the University of Wisconsin-Green Bay, the site features an interactive, dichotomous key to the ferns and "fern allies" of the state, as well as a checklist of Wisconsin ferns and a glossary of fern terminology. Really helpful if you want to learn more about how to identify the species you might come across in this part of the country.

A Female! Ready to Mate!
One more non-fern post for tonight. I just discovered this series of short films called Green Porno at the sundance channel site. They are written/directed/star Isabella Rossellini as a variety of insects and arachnids, explaining their sexual practices in about 30 seconds. They are very imaginative and intriguingly done and I enjoyed watching them.
Teach the Controversy
Ferns on the Mall
I'm afraid I won't have many more opportunities for fern-viewing until late July, when I go to Vancouver, B.C., Washington State, and Oregon, for the annual Botanical Society of America conference and some time in the field. The blog will likely be light until then, as I wrap up this stint in D.C. and head home to Madison. I should have a lot to write about once that next trip begins!
