1905] ARTHUR—RUSTS FROM MEXICO 389 
12. Uromyces Clitoriae, n. sp.—Uredosori hypophyllous; uredo- 
spores globoid, about 23-27# in diameter, wall thick, 3, fuscous, 
evenly and sparsely echinulate, pores apparently 2: teleutosori hypo- 
phyllous, small, round, scattered, dark cinnamon-brown, soon naked; 
teleutospores ellipsoid, 20-24 by 22-30#, wall chestnut-brown, 
evenly thick, 33.5, minutely and evenly verrucose; pedicel delicate, 
colorless, less than the length of the spore, caducous.—On Clitoria 
mexicana Link, Jalapa, Oct. 5, 1898, no. 3088. 
Only a few uredospores were seen, which were found in- parasitized sori. 
The sculpturing of the teleutospores is minute but very distinctly shown when 
13. Uromyces bauhiniicola, n. sp.—Spermogonia epiphyllous, 
gregarious, punctiform, fuscous, subepidermal, seen in section 
globose, 60-130 in diameter: teleutosori at first hypophyllous, 
becoming amphigenous, small, round, about 1™™ in diameter, 
often confluent, early naked, blackish; teleutospores broadly oval 
or globoid, 15-21 by 20-24; wall dark chestnut-brown, semi- 
opaque, thick, 2.5-—3.5, prominently rugose, thicker and paler at 
apex, 5-7#; pedicel colorless, firm, as long as the spore——On Bau- 
hinia Pringlei Wats., Guadalajara, Sept. 28, 1903, no. 5060 (type): 
Bauhinia sp., Iguala, Nov. 4, 1903, no. 5334- 
Readily distinguished from the four or five species occurring upon Bauhinia 
in South America by the very dark, rugose spores, unaccompanied by uredo- 
spores. The spores germinate somewhat readily in the sori, not long after 
maturity. 
14. PHRAGMOPYXIS DEGLUBENS (B. & C.) Diet.—On Brit- 
tonamra Edwardsii (A. Gr.) Kuntze (Cracca Edwardsii A. Gray), 
Cuernavaca, Oct. 30, 1903, no. 5278. 
This is the first time the host of this rare and interesting species has been 
definitely determined. It has only twice been reported before, once in Ecuador 
on an undetermined species of Coursetia, a genus closely related to Brittonamra. 
The type collection is recorded on “leaves of some leguminous plant,” and is 
said to come from Texas (Grev. 3:55), which latter, however, must be an error. 
The specimen in the cryptogamic herbarium of Harvard University says, “ North- 
ern Sonora,” and bears the collector's number, the same as recorded by BERKELEY 
in Grevillea. A specimen in the herbarium of the Department of Agriculture at 
Washington, D. C., says “N. Mexico,” but does not bear the collector's number. 
Both of these specimens are undoubtedly part of the one original collection made 
by C. Wright. The Washington specimen consists of two leaflets, 5 by 12™™,
