106 SEMI-CENTENNIAL OF TORREY BOTANICAL CLUB 
from the Herb. Curtis, which has been seen, shows uredinia, and 
it is doubtless to be refererd to Uromyces proeminens. See no. 48. 
727. Trichobasis labiatarum Lév., on “leaves of Labiatae,” in 
Fungi Cubenses. A portion of the collection from the Herb. 
Curt. has been seen, but the species represented remains uncertain. 
It may be some species on Leonotis, Hyptis, or Salvia. 
730. Puccinia Cynanchi Schw., on “the leaves and stem of 
some Asclepiad," in Fungi Cubenses. The collection has not been 
seen, although the type of P. Cynanchi from Surinam has been 
examined, and the Wright collection may well be the same species. 
It is now referred to P. Gonolobi. See no. 88. 
756. Aecidium Rivinae B. & C., on “racemes of Rivina octandra,” 
in Fungi Cubenses. The collection has not been seen, but there 
is no doubt regarding the names. The species is now referred to 
Puccinia Rivinae (B. & C.) Speg. See no. 74 
929. A collection іп the Herb. Curtis, which has been examined, 
is labelled Aecidium Nymphaearum DC., оп Limnanthemum 
Grayanum Griseb., and doubtless correctly so. The species is 
now referred to Puccinia Scirpi. See no. 69. 
Mr. Otto E. Jennings, accompanying a natural history expedi- 
tion* from the Carnegie Museum of Pittsburgh, Pa., collected in 
the Isle of Pines from May 5 to May 26, 1910. One rust collection 
(cf. no. 89), and one phanerogamic specimen bearing a rust (cf. no. 
60), were obtained at this time. 
Beside the above collectors of fungi, who have enriched our 
knowledge of the rust flora of Cuba, there are some fourteen botan- 
ists, whose names appear in the following list in connection with 
phanerogamic specimens from the island, found to bear rusts. 
Altogether half a hundred botanists are represented as field col- 
lectors in the present account of the rusts of Cuba, to whom is due 
the credit of making material available as a basis for this first 
account of the Cuban rusts. 
Comparison of the list as it now stands with the list of rusts 
for Porto Rico, bringing the last published account of the latter 
up to date in order to make the two more accurately comparable, 
shows a close agreement in the number and kind of genera and in
