588 ArTHUR: NEw UREDINEAE 
not noticeably laminate, medium thick, 2.5-3, sparsely and 
strongly verrucose, pores 2, opposite and equatorial. 
III. Telia hypophyllous, minute, scattered, or crowded into 
seemingly pulvinate groups of 0.2-1 mm. across, early naked, 
blackish, ruptured epidermis not noticeable; paraphyses numer- 
ous, peripheral, united at the bases, terete, 9-10 X 55-644, 
acuminate, somewhat incurved, wall firm, about. 2 » thick, dark 
chestnut-brown, smooth ; teliospores few in a sorus, broadly ellip- 
soid, 24-27 x 32-39 4, rounded at both ends, slightly constricted 
at the septum, wall chocolate-brown, rather thick, 3.5-4.5 », gela- 
tinous layer golden-yellow, not conspicuous except at apex and 
sometimes at base where it produces an umbo-like thickening of 
2~-3 pt, closely and rather coarsely verrucose ; pedicel pale amber- 
colored throughout, once to once and a half length of spore, with 
- whorl of rather large, much branched appendages, near the 
ase. 
On Tecoma bahamensis Northrop, New Providence, Bahamas, 
March 12-24, 1907, Elizabeth G. Britton 6596. A. very distinct 
species, intermediate in the character of its appendages between P. 
appendiculatum and P. Amphilophii. The paraphyses are particu- 
larly noteworthy. Being large and stout, and very dark-colored, 
they are especially conspicuous. But they are unique in the way 
in which they adhere at the bases to form a circle about the spores. 
The sorus may be readily separated ‘as a whole from the tissue of 
the host, with the spores in place. It then appears campanulate, 
like a partially opened flower, borne on a slender, pale pedicel, 
which is formed of the greatly compressed portions of the para- 
physes and spore-stalks where they pass through the epidermis. 
Calliospora Petalostemonis sp. nov. 
O. Pycnia chiefly hypophyllous, preceding or accompany ing 
the telia, numerous, scattered, conspicuous, golden-yellow becom- 
ing brown, subcuticular, conical, 80—1 toy wide, about half as 
high ; ostiolar filaments 30-50 p long. 
III. Telia hypophyllous, scattered, small, roundish, 0.3-0.6 
mm. across, chocolate-brown, somewhat pulverulent, ruptured 
epidermis somewhat noticeable; teliospores ellipsoid, 23-29 * 
35-45 #, rounded at both ends, slightly or not constricted at sep- 
tum, wall laminate, inner layer light chestnut-brown, medium 
thick, 2~2.5 , pores two in each cell, lateral and opposite, outet 
layer gelatinous, pale-yellow, rather thin, 1-1.5 4, very finely and 
rather sparsely verrucose ; pedicel colorous, about 6 y in diameter, 
short and largely deciduous, not swelling in water.
