Uromyces Pist Pars. ? on Clcer arletiniim L, (" Clianna ").
I obtained some good specimens of a fungus on this host, also
from Dumraon, gathered on 4th April. There were small circular
or oval brownish pustules on the leaflets, with a tendency to
coalescence. They were both epi- and hypophyllous, though
apparently more often hypophyllous.
The uredospores are brownish red, mostly spherical, sparsely
covered with spines, and each apparently with four germ-pores
(fig. 5). The dry spores, just immersed in water, measured
25-20 X 21-20 /x. I placed some of these spores in water on the
2nd May, and they germinated freely in twenty-four hours, throwing
out a long, simple, unbranched tube, quite colourless (fig. 5, a,).
This germination a month after gathering is noteworthy. I could
find no teleutospores in the specimens gathered, and as these were
full-grown and ready to reap, I conclude none are formed.

Uromyces Pisi Pers. on Lathyrus sativus L. (" Khesari").
From Dumraon I obtained specimens also of this plant bearing
a Uromyces, gathered on 4th April. There were numerous dark
pustules, round to oval or broadly linear, on the stem mostly, but
also on the leaves. On the latter they are apparently amphigenous.
The pustules contained both uredo- and teleutospores, the
latter in excess.
The uredospores are orange-red, with a tendency to brownish.
They are oval for the most part, spiny, and with five to six germpores
(fig. 6, c). The dried spores just immersed in water
measure 28-23 x 22-20 /x. These spores, after lying twenty-four
hours in water, had germinated freely, throwing out a single, long,
unbranched tube, at the distal end of which were collected the pale
reddish brown contents, leaving the empty spore-case dingy
yellow (fig. 6, a). The spores now measured 25-21 x 24-21 /^. I
observed the uredospores germinating even as late as the middle of
June, i. e., more than two months after they were gathered.
The teleutospores are more or less oval and chestnut-brown, but
vary considerably in size and shape (fig. 6, d). A nuclear space
and germ-pore at the apex are clearly visible. The epispore is
