Arthur : Uredinales of Porto Rico 
189 
It has not been possible to examine type material of Uredo 
Desmodii-tortiwsi P. Henn. (Hedwigia 35: 252. 1896), which 
was founded on a collection of Meibomia tortuosum from 
Fajardo, P. R., April 17, 1885, O. Sintenis. However, the claim 
of the author that it is distinct from Urom. H edysari-paniculati 
by reason of its smooth spores, seems open to doubt. As no 
rust is known having truly smooth urediniospores, it is probable 
that Hennings’ material possessed fine echinulation, which was 
overlooked. As all other terms of the characterization accord 
well with the common species on Meibomia, it may tentatively be 
assumed that the form named by Hennings is not essentially 
distinct.

On Fabaceae: 
Clitoria cajanifolia (Presl) Benth. (Neurocarpum cajani- 
folium Presl), Mayagiiez, Jan. 30, 344; without locality 
or date (in letter dated June 18, 1913), 2146c. 
Clitoria rubiginosa Juss. (C. glycinoides P. DC.), Dorado, 
Nov. 25, 3314, 5315. 
No pycnia or aecia have yet been discovered for this species, 
but it is highly probable that they occur occasionally. Telia, in 
addition to uredinia, are shown only on no. 344 of the specimens 
here listed. 
The type collection of U. insularis was on C. cajanifolia, from 
Dorado, P. R., 1887. The species was also collected on this 
host near San Juan, in 1914, by Britton and Cowell On 
C. rubiginosa it has been found at Santurce, P. R., Feb., 1914, by 
J. R. Johnston 1339, and in both Jamaica (1906) and Cuba 
(1903)-
