New germplasm from Dylan’s 2015 field work

As many of you know, I was tasked with collecting wild populations of Helianthus annuus, H. petiolaris, and H. argophyllus from across the geographic range of the species, for use in the abiotic stress adaptation project. Over a three month period, I drove more than 30,000 miles and collected at 145 Helianthus localities in 15 western states. I found a lot of really interesting plants, including what might be several new species. In future posts, I’ll talk some more about the trip, and what I found.

The seeds are now here. They are cleaned and packaged in individual envelopes numbered by population and mother plant. I cleaned the seeds in Ames, Iowa at the UDSA facility, so they are high quality, ready to go. All of the seeds are now part of the seed collection in our lab in the Biodiversity building. The new seeds have been added to the permanent database of seeds for the whole lab. But I also put a copy of my complete notes here. My notes give details about where the plants were collected, their ecology, etc. I’ll be putting printed data in the boxes with the seeds as well, just in case the zombie apocalypse arrives and these electronic data go dark. I also plan to post photos of each population I visited, but that’s down the line. For now, the seeds are here, so if you need to access any of them for a project, the data linked to this post should help you do that. If you happen to use any of these plants in a project, please note that voucher specimens were deposited in the herbarium at Indiana University (herbarium code: IU).

If you need to contact me about these seeds, and you have no idea who I am or where I am located, here is my “permanent” email address, which should also last for some time.


Herbarium Vouchers

In a recent lab meeting, the issue of herbarium vouchering came up, and a spirited discussion ensued. Inspired by what I heard there, and by some discussions with the manager of the UBC Herbarium, I decided to create a post on the how and why of herbarium vouchering. I put the complete version of this on my own research blog, accessible here. Here, I mostly wanted to summarize the idea, and try to convince everyone in the lab that vouchering is really important.
