31. Puccinia semiinsculpta, n. sp.—Uredosori amphigenous, 
scattered, round, small, o.2-0.3™™ across, cinnamon-brown, soon 
naked, pulverulent; uredospores broadly elliptical or globoid, 17-25 
by 22-284, wall 2m thick, echinulate, pores indistinct, probably 3 
and equatorial: teleutosori amphigenous, or often only epiphyllous, 
scattered, round, small, o.2-0.5™™ across, often confluent, soon 
naked, pulverulent, chocolate-brown, or compact and cinereous 
from germination; teleutospores broadly elliptical or elliptical- 
obovate, 25-36 by 40-50, round at both ends, or narrowed below, 
slightly or not constricted at septum, wall finely to coarsely reticulate- 
verrucose, thick, 4-6, slightly or not thickened at apex, 5-0/; 
concolorous, often thinner below; pedicel colorless, 4-7# thick, once 
to twice length of spore, more or less minutely rough.

Patzcuaro, Oct. 17, 1898, no. 3105, Oct. 10, 1899, no. 3602, Oct. 13; 1899, no.

no. 3540; Oaxaca, Oct. 18, 1899, no. 3668. 
The different collections vary in appearance. In some of the collections 
most or all of the sori are dark and pulverulent, in others they are compact an 
pale from germination, while in others its two forms are variously intermixed. 
The spores from germinating sori are thinner-walled, lighter-colored, and more . 
obovate. The extreme forms are quite unlike, but all gradations occur, even 
on the same leaf. The uredosori are quite inconspicuous. : 
32. Puccinia egregia, n. sp.—Uredospores from the teleutosor 
globoid, 23-26 by 24-28x, wall golden-yellow, rather thin, echinulate, 
pores 3, equatorial: teleutosori amphigenous, scattered, pulvinate, 
chocolate-brown; teleutospores ellipsoid, 27-30 by 35-464; round 
at both ends, slightly or not constricted at septum, wall thick, 4-6, 
slightly or not thickened at apex, coarsely and prominently verrucose, 
with conical and well separated papillae; pedicel colorless, 5-6# 
thick, twice length of spore. 
On Vernonia uniflora Schz. Bip., Oaxaca, Dec. 29, 1895, no. 1739 (Seler). 
This specimen was obtained in looking over the phanerogamic herbarium at 
the New York Botanical Garden. It is a very marked species. The host was
