Tripterocladium A. Jaeger, 1880.



Tripterocladium, throughout its range, is very unpredictable as to site of occurrence with each of its occurrences south of the Canadian border representing a considerable disjunction of range. In the field, Tripterocladium resembles a very small Pterigynandrum, but it has smooth rather than prorate cells. Tripterocladium is known in California from a single Siskiyou County collection.
