UREDINALES OF GUATEMALA

O'Donovan, They agree in every way with those of the scanty type 
material from Nicaragua, and show that they are not ''one sHghtly 
higher on the pedicel than the other," as given in N. Am. Flora 7: 147, 
but that the two spores of each pair are borne side by side. It now 
seems probable that the host of the Nicaraguan collection is E. glauca, 
or at least a species of the genus with similarly thick, glaucous leaves. 
The rust also occurs on E. umhrosa H.B.K. in Trinidad, W. I., where 
it was collected by J. B. Rorer, Oct. 21, 191 6. 
44. Tranzschelia punctata (Pers.) Arth. (on Amygdalaceae). 
Prunus sp., San Rafael, Dept. Guatemala, Jan. 7, 1915, II, 28. 
This long-cycle, heteroecious species was collected by Kellerman 
on Amygdalus persica L., at Antigua, Feb. 15, 1905, II, 5J55*, and 
reported by Kern in Journ. Myc. /. c, under the early name, Puccinia 
Pruni-spinosae Pers. 
45. Phragmopyxis deglubens (Berk. & Curt.) Dietel (on Fabaceae). 
Benthamantha cinerea (L.) Kuntze, Guatemala City, Dec. 20, 1916, 
II, iii, doy. 
Only a meager amount of the fungus was found. It differs slightly 
from collections made in Mexico upon other species of the same host- 
genus by the teliospores possessing a short apiculus and a less gelat- 
inous layer in the wall. 
46. Uropyxis sanguinea (Peck) Magn. (on Berberidaceae). 
Mahonia pinnata (Lag.) Fedde. 
A collection of this widespread, long-cycle rust, having pycnia, 
uredinia, and telia, was made by Kellerman at Volcan de Agua, Dept. 
Sacatepequez, Feb. 15, 1905, II, 4624, and reported by Kern in Journ. 
Myc. /. c. 
47. Uropyxis Crotalariae Arth. sp. nov. (on Fabaceae). 
Crotalaria sp. 
Uredinia amphigenous, oblong or irregular, large, 0.5-1 mm. long, 
soon naked, pulverulent, cinnamon-brown, ruptured epidermis some- 
what overarching and conspicuous; urediniospores ellipsoid or globoid, 
18-26 by 23-30 ^t; wall golden-brown to Hght yellow, 2-2.5 thick, 
moderately echinulate, the pores 6-8, scattered. 
Teha chiefly epiphyllous, like the uredinia but smaller, 0.1-0.2 mm. 
across; teliospores globoid, 26-30 ijl in diameter, the septum wanting; 
wall hygroscopic, the inner, firm portion dark chestnut-brown, 2-2.5 M 
thick, the outer gelatinous layer yellow, swelling to 5-6.5 ii thick, the 
colorless cuticle sparsely verrucose; pedicel short, colorless, largely 
evanescent.
