I am working on a project concerning Pyrola from the Pacific Northwest-- as justification for the recognition of a new species, I am comparing the nuclear and chloroplast phylogenies for PNW Pyrola picta (green), P. "crypta" (yellow), P. dentata (blue), and P. aphylla (red). At first I thought that samples falling at the base of …
Black Lassic
Black Lassic is one peak among the Lassics of Trinity County and is characterized by outcrops of serpentine, mudstone, and sandstone surrounded by coniferous forest. Pyrola crypta is a species that grows predominantly under Pseudotsuga in this area. It is very similar in appearance to P. picta but can be distinguished by its unusually long sepals …
Cascadian species of Pyrola
While trying to understand relationships among populations of Pyrola picta by comparing DNA sequences, I came across a group of sequences that seemed to be divergent from the rest. The DNA sequences corresponded, at least loosely, to populations in the Cascade Mountains of Washington, Oregon, and northern California (Fig. 1) of plants that look like …
