ARTHUR AND JOHNSTON: UREDINALES OF CUBA 163 
Aecia hypophyllous, scattered or indefinitely grouped, cupu- 
late, short, 0.08-0.15 mm. in diameter; peridium white, margin 
erect, lacerate, the peridial cells rhomboidal, 21—29 y long, slightly 
or not overlapping, the outer wall rather thick, 4—7 и, the inner wall 
somewhat thinner, 2.5—4 и, rugose; aeciospores globoid, 21—26 by 
25-29 и; wall colorless, rather thin, 1—1.5 и, very finely and closely 
verrucose. 
The material on which this species is founded is scanty, being 
only a few small leaves from seedlings. The aecia on them are, 
however, quite numerous. In reference to the host, and the place 
where it was found, the collector has the following to say. 
" [n regard to the host there seems to be little chance for mis- 
take. The seedlings have 3-5 leaflets identical with those of 
Tecoma. Тһе leaflets are very narrow but so are they on the 
mature flowering plants in this locality, that is to say on the first 
branches. The later leaflets become of a normal width. In one 
case the same fungus was found on one leaf of a plant 2 feet high, 
while the most of them had only the cotyledonary leaves or per- 
haps the second and third pair affected. 
“The location of this plant was unique—in the basin at the 
foot of a waterfall about a hundred feet high, with constantly 
moist condition about the basin. Seedlings were growing on the 
moss-covered rocks, and mature plants overhanging the boulders 
in the river. It is regretable that the locality is so isolated.” 
Assuming that this form is a genuine aecium, for the spores 
have not yet been germinated, the probability of its being autoe- 
cious or heteroecious remains an open question. 
118. AECIDIUM FARAMEAE Arth. Bull. Torrey Club 42:592. 1915. 
ON RUBIACEAE: 
Faramea occidentalis (L.) A. Rich., San Diego de los Bafios 
(Prov. Pinar del Rio), Aug. 31-Sept. 3, 1910, Britton, 
Earle & Gager 6855. 
Only the type collection cited above is known. The germina- 
tion of the spores has not yet been observed, and it is by no means 
certain that it is not a species of Endophyllum. The more suc- 
culent part of the host is often greatly distorted by the rust. 
Form-genus UREDO, with paraphyses imbricated to form a pseudo-peridivm, 
or with cells united into a peridial membrane, mostly forms belonging to UREDIN- 
ACEAE (MELAMPSORACEAE), nos. II9—I2I
