Saxifrages and Toads near Loletta Lakes
The photographic highlight of the day had to be this cluster of trilliums visited by a pale swallowtail. The butterfly was as enthralled as we were and stayed for at least 10 minutes, allowing me to get over 40 photos from every angle.
For months, I’ve been working on and off to finish editing and doing the layout for the Saxifragaceae treatment for Volume 3 of the Flora of Oregon (I finally finished it so I felt I could take a break to write this report, however late). I had enough space to add a couple of illustrations and wanted to do two of the more interesting species, rusty saxifrage (Micranthes ferruginea) and Merten’s saxifrage (Saxifraga mertensiana). Our lead artist, John Myers, does most of the illustrations, but he has so many to do right now that I’m contributing a few of the species I’m familiar with.
Both these species are unusual in that they are able to produce asexually by vegetative offsets. Rusty saxifrage has tiny plantlets in the inflorescences that replace most of the flowers except the terminal ones. These drop to the ground and form colonies of clones beneath the mother plant. Mertens’ saxifrage often produces clusters of red bulblets in the inflorescences. Like the rusty saxifrage, these replace the lower flowers. From what I’ve read, it produces these bulblets in most of its range. In the Western Cascades, however, I’ve only seen them in a few populations. One of these is along Coal Creek Road 2133 on the way up to Loletta Lakes. Read the rest of this entry »
