ARTHUR AND JOHNSTON: UREDINALES OF CUBA 145 
This short-cycle rust, common in tropical America, was de- 
tected on a phanerogamic collection in the herbarium of the N. Y. 
Bot. Garden, obtained along the railroad near Cerro (Prov. 
Habana), April 13, 1903, J. A. Shafer 183.

This autoecious species, having pycnia, uredinia, and telia, is 
discussed in the Stevens' list of Porto Rican Uredinales (Mycolo- 
gia7:237—238. 1915). The collection by Wright, по. 282, is the 
second one of the two numbers cited under the original description 
of Uromyces gemmatus B. & C. (Jour. Linn. Soc. 10: 356. 1869), 
a species said to be on “ ће underside of leaves of Convolvulus, &c.” 
The first number there cited (278) is on a Convolvulaceous host 
(see 51), and the second number must, therefore, represent the 
“с.” Wright's collection was ample, and the host was deter- 
mined from material in the Curtis herbarium by Percy Wilson of 
the New York Garden, Jan. 13, 1915, as Gouania polygama. The 
authorities of the Kew herbarium kindly sent a fragment of 282 
to the senior author, which agrees perfectly with that in the 
Curtis herbarium.
