574 ARTHUR: NEW SPECIES OF UREDINEAE 
Cooke. This led De-Toni to rename the South American rust. 
Still later names for the latter are Uredo ochracea Dietel, founded 
on a Brazilian collection, and Uredo commelinacea Ellis & Kelsey, 
founded on a West Indian collection. 
There is no direct evidence to show whether the species pos- 
sesses aecia or not; but as nearly all rusts on monocotyledonous 
hosts do have aecia so far as their life cycles are known, it is a 
fairly safe inference that aecia will eventually be found for this 
species. 
Uromyces Coluteae sp. nov. 
Oand I. Pycnia and aecia unknow 
II. Uredinia hypophyllous, seatigred’ roundish, small, 0.2— 
0.3 mm. in diameter, soon naked, somewhat pulverulent, pale 
cinnamon-brown, ruptured epidermis conspicuous; urediniospores 
broadly ellipsoid or globoid, 18-24 by 21-27; wall golden brown, 
moderately thick, 1.5—2y, finely and rather closely echinulate; pores 
3, rarely 4, equatorial. 
Ill. Telia hypophyllous, scattered, roundish, small, 0.2—0.3 
mm. in diameter, soon naked, chestnut-brown, ruptured epidermis 
noticeable; teliospores broadly ellipsoid or obovoid, 15-19 by 19- 
23u; wall cinnamon-brown, rather thick, 1.5-2u, with a small 
hyaline papilla over the germ-pore at apex, moderately and evenly 
verrucose; pedicel short, hyaline, deciduous. (F1GuRE 1, A.) 
On Colutea arborescens L., Manhattan, Kansas, August, 1887, 
W. A. Kellerman & W. T. Swingle 1650; Sept. 1, 1890, W. T. 
Allen 1205. This Old World species was found on plants in the 
nursery and grounds of the State Agricultural College of Kansas. 
It has heretofore been listed under the name Uromyces Genistae- 
tinctoriae, a combination first used by Winter in Die Pilze, 1881. 
Winter united a number of forms under the name, because, as he 
says, he was not in a position to decide upon diagnostic characters. 
The species differs from the genuine U. Genistae-tinctoriae, which 
is common in Europe on various species of Genista, Cytisus, and 
Laburnum, by having three equatorial pores in the urediniospores 
instead of three to six scattered pores, and by the evenly verrucose 
teliospores instead of those more or less striate (see figure). Spores 
of intermediate character are not rare. The type collection se- 
lected for the new species is the one issued as no. 403 in Sydow’s 
Uredineen, collected at Meran, Austria, Sept. 13, 1890, by Dr. 
P. Magnus.
