host and of the host found at Brownsville shows that the two are apparently 
identical. Ravenelia gracilis was —— common i in the vicinity o of B rownsville 
this species the urediniospores are given as obovate and the teliospore heads 
as bearing 4~-7 colorless tubercles to each spore. The writer, however, failed 
to find any obovate urediniospores in that portion of the type collection which 
is in his herbarium. The teliospore heads of the type show many heads with 
smooth tops but with short tubercles around the margin, while other heads in 
the same mount have shorter and fewer warts to each spore at the top than on 
the margin, thus agreeing in every detail with the Brownsville material. 
RAVENELIA LEUCAENAE Long 
This species was collected by the writer near Brownsville, Texas, 
on Leucaena pulverulenta. There are certain minor characters of 
this rust not given in the published description of it that are worth 
_ recording. The urediniospores on this host are mainly concolorous, 
often with the apex slightly thickened. The teliospore heads are 
5-6 cells across, with 5-16 marginal spores and 3~14 inner ones, 
usual size 14-16 spores per head, each spore at top of head bears 
from o to 2-4 very short tubercles, while there are 4-6 Lome or 
slightly curved tubercles, 4-64 long, on each spo.
