ARTHUR: NEW SPECIES OF UREDINEAE 149 
Puccinia Notopterae sp. nov. 
, O. Pycnia amphigenous, crowded on brownish areas 2-3 mm. 
across, dark brown, conspicuous, subepidermal, globoid, 85-140 u 
in diameter, with ostiolar filaments. 
III. Telia epiphyllous, becoming amphigenous, circinating 
about the pycnia at first, then becoming confluent and causing 
hypertrophy, early naked, very pulverulent, chestnut-brown, 
ruptured epidermis noticeable; teliospores ellipsoid, 19-24 by 
26-34 wu, rounded at both ends, slightly constricted at septum; wall 
dark cinnamon-brown, evenly 1.54 thick; coarsely and rather 
sparingly verrucose; pedicel colorless, short, fragile. 
On Notoptera hirsuta (Sw.) Urban, Mandeville, Jamaica, 
February 23, 1915, E. W. D. Holway 226. A distinctive, short- 
cycle rust, on a host genus not before represented among those 
bearing rusts. 
Aecidium anthericicola sp. nov. 
O. Pycnia amphigenous, in small orbicular groups, small, 
honey-yellow, inconspicuous, subepidermal. 
I. Aecia hypophyllous, in annular groups 2-7 mm. across about 
the pycnia, at first bullate then erect, the margin erose; peridial 
cells quadrate, 16-20 by 20-26 un, abutted, the outer wall slightly 
or no thicker than the inner wall, 3-6 uw; aeciospores globoid, 16-20 
by 19-23; wall colorless, thin, 1.54, very finely verrucose, ap- 
pearing smooth when wet. 
On Anthericum nanum Baker, Dedregal near Tlalpam, Valley 
of Mexico, Mexico, June 30, 1905, Rose, Painter & Rose 8246. 
The species is similar to the aecia of Uromyces Hordei on Notho- 
scordium, but both the peridial cells and aeciospores are smaller 
than in that form. 
Aecidium plenum sp. nov. 
O. Pycnia amphigenous, crowded in groups 0.2-0.3 mm. across, 
cinnamon-brown, small, inconspicuous, subepidermal. 
I. Aecia hypophyllous, crowded in circular groups about the 
pycnia, I-2 mm. across, without conspicuous spots, cupulate or 
short cylindric; peridium erect, or somewhat recurved, irregularly 
and deeply lacerate; peridial cells angularly oblong in face view, 
about 20 by 30, narrowly oblong in radial section, somewhat 
overlapping, about 8-10 by 304, the outer wall 5-9 u thick, smooth, 
the inner wall 3-6 yu, coarsely verrucose; aeciospores globoid or 
ellipsoid, 16-21 by 18-244; wall colorless, thin, Iu, finely and 
closely verrucose.
