P. flaccida, B. & Br. 
IL, TU. Amphigenous. Sori small, oblong to linear, 
often confluent, at length rupturing the epidermis, reddish-fer- 
ruginous. Uredospores vary from - elliptical to subglobose, the 
latter about 25 uw, furnished with two or more hyaline points 
(germinal pores?), sharply echinulate, cinnamon-colored. Te- 
leutospores exceedingly variable, often undivided, the septum, 
when present, transverse, oblique or longitudinal, equally, or in 
every degree unequally, dividing the spore. The simple ones 
are usually clavate, the divided ones vary from clavate to sphe- 
roidal, regularly formed or much constricted, and lobed with 
one or two thickened apical points, length about 30-402, light- 
er colored than the uredo; pedicel hyaline, once or twice the 
length of the spore. 
Sori small, short; spores flaccid, with a long hyaline pedicel, ob- 
tuse, contracted in the middle.—Berkeley, Jour. Linn. Soc., Vol. XIV.,

A most peculiar species. From two thirds to three fourths 
or more of the teleutospores are septate, presenting the most 
varying and aberrant forms. So far as we are informed this 
has not been previously found in America, but a comparison 
with specimens kindly furnished by Dr. M. C. Cooke, of Puc- 
cinia flaccida, B. & Br., from Ceylon, leaves no doubt of the 
specific identity. The American specimens only differ in pos- 
sessing more undivided, and upon the average, narrower teleu- 
tospores, with somewhat thicker pedicels.

II., II. Hypophyllous. Sori rather small, usually very 
numerous, elliptical, sometimes confluent in small, elongated 
groups, soon naked, surrounded by the lacerated remains of the 
epidermis; uredospores subglobose, epispore rather thick, tuber- 
culate, 21-80u; teleutospores mostly obovate, but varying to 
elliptical and clavate, slightly constricted at the septum, usually 
thickened at the vertex, obtusely rounded or sometimes short-
