Arthur: Uredinales of Porto Rico 69 



30. Uromyces Hedysari-paniculati (Schw.) Farl. {Uredo 



Desmodii-tortuosi P. Henn.). 

 On Fabaceae : 

 Meibomia S cor plums (Sw.) Kuntze (Desmodium Scor- 



piurus Desv.), Mayagiiez, March 20, II, 218. 

 Meibonia tortuosa (Sw.) Kuntze (Desmodium tortuosum 

 DC), Yauco, March 31, II, 220. 

 Through the kindness of Dr. Lindau of the Berlin Museum, 

 the writer has recently been able to examine the spores from the 

 original collection made by Sintenis at Fa jar do in Porto Rico 

 and established by P. Hennings as a new species under the name 

 Uredo Desmodii-tortuosi. The examination of this material con- 

 firms the prediction in connection with the discussion of the 

 Stevens material (Mycol. 7: 189). The spores do not in any 

 way differ from the urediniospores on other collections of the 

 same or other hosts, they being finely verrucose, and not smooth 

 as stated in the original description. 



31. Uromyces Sabineae sp. nov. 

 On Fabaceae: 



Sabinea punicea Urban, Maricao, Rio Grande river, 

 March 23, II, III, 182. 



Uredinia hypophyllous, scattered, or somewhat gregarious on 

 slightly reddish, effused spots, applanate, round, 0.1-0.2 mm. 

 across, soon naked, light cinnamon-brown, pulverulent, ruptured 

 epidermis evident ; urediniospores globoid or broadly obovoid, 

 18-20 by 19-26 yu; wall light yellow, thin, about 1.5/*., moderately 

 echinulate, the pores fairly distinct, 3 or occasionally 4, equatorial. 



Telia hypophyllous, scattered or somewhat gregarious, pul- 

 vinate, round, 0.1-0.3 mm. across, early naked, blackish-brown, 

 ruptured epidermis evident ; teliospores globoid, 20-24 by 22-29 H- 5 

 wall dark chestnut-brown, moderately thick, 3 thicker above, 

 4-7 n, moderately verrucose; pedicel colorless, one half to once

The collection shows about an equal abundance of well- formed 

 uredinia and telia.
