ARTHUR: NEW SPECIES OF UREDINEAE 145 
termined species of Heliconia (Bihai). In North America it was 
collected in Martinique, West Indies, on Bihai borinquena Griggs, 
August, 1913, and again by Whetzel and Olive in Porto Rico, West 
Indies, on the same host, April, 1916, both collections showing 
only uredinia. In a collection on Béihai latispatha (Benth.) 
Griggs, made by E. Bethel, at Montelinio, Canal Zone, Panama, 
March 4, 1913, an abundance of telia accompany the uredinia. 
The characters of the telia are as follows: 
III. Telia hypophyllous, scattered, soon naked, round, o. 3-0. 
mm. across, cinnamon-brown, ruptured epidermis evident; telio- 
spores elongated clavate, 15-19 by 60-724, rounded above, not 
or slightly constricted at septum; wall pale cinnamon-brown, thin, 
I w, much thickened above, 9-13 4, smooth, pedicel short, colorless. 
: The urediniospores of this species appear to be quite variable. 
Those of the West Indian collections are thin and dark, as com- 
pared with most of those of the Panama collection, in which, how- 
ever, all gradations occur. The sori of the present material are 
much parasitized, and both uredinia and telia are consequently 
unnaturally conspicuous. 
Puccinia Viornae sp. nov. 
O. Pycnia epiphyllous, crowded upon swollen areas 2.5-5 mm 
in diameter, dark brown, noticeable, subepidermal, globoid, 
98-110 uw in diameter, with ostiolar filaments 
I. Aecia hypophyllous, crowded upon swollen areas opposite 
the pycnia, cupulate, short, 0.2-0.5 mm. in diameter; peridium 
recurved, the peridial cells rectangular, abutted, 19-23 by 22-24 u, 
the outer wall 7-9 u thick, the inner wall 3-5» thick, finely ver- 
rucose; aeciospores irregularly globoid or ellipsoid, 13-16 by 14- 
18 »; wall colorless, thin, 1.5 u, finely and closely verrucose. 
II. Urediniospores in the telia, ellipsoid or elliptic-obovoid, 
16-19 by 24-324; wall pale golden-brown, thin, 1-1.5 4, thicker 
above, 3-5 , closely echinulate, the pores indistinct, 2 or possibly 
more, equatorial; paraphyses in the telia, intermixed with the 
spores, or surrounding groups of spores, cylindric, clavate or 
clavate-capitate, 7-23 by 47-644u, the wall nearly colorless to 
golden-brown, darker above, thin, I-1.5 4, somewhat thickened 
above, 2—7 u 
Il. Telia caulicolous, scattered, oblong or linear, 1-3.5 m 
long, somewhat tardily naked, inclined to be pulverulent, a 
nut-brown, ruptured epidermis conspicuous; paraphyses sparingly
