Discussion

Variety piscinensis is known from Fish Slough northwest of Bishop in Mono County. It is similar in habit to vars. multiracemosus and sesquimetralis.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Variety negundo, which is known from Box Elder, Millard, and Tooele counties, fills a portion of the gap in distribution between var. platyphyllidius, with which it shares relatively thick-textured fruits, and var. chartaceus, with which it is transitional to the south. From either taxon, the elongated fruit is evidently diagnostic, apparent only as fruits approach maturity. The lower flower number is characteristic of var. negundo and is more or less diagnostic.
