Description
Variety Description - Essentially like the sympatric forms of var. angustata with relatively long, long-beaked, distantly aculeate pods, but the lfts prominulously pallid-venulose dorsally, the midrib 1-2- branched above mid-blade or rarely simple.
Distribution and Ecology - In palmetto scrub and on white sands of middle and n.-e. Florida and extreme s.-e. Georgia, within and partly overlapping the range of var. angustata (Isely, 1973, map 48, sub Schrankia floridana).—Fl. IV-IX.
-
Discussion
The var. floridana resembles var. nuttallii in leaflet-venation, but the leaflets are only minutely apiculate or obtuse, not sharply triangular-apiculate, and the capitula are on the average smaller.
