﻿Arthur: New species of Uredineae 593 



On Faramea occidentalis (L.) A. Rich., San Diego de los Banos, 

 province of Pinar del Rio, Cuba, August 31 to September 3, 1910, 

 Britton, Earle & Gager 6855. The deep-seated pycnia and aecia 

 are especially characteristic of this species of rubiaceous rust. It 

 may or may not be heteroecious. 



Uredo fatiscens sp. nov. 



II. Uredinia amphigenous, scattered or somewhat striate on 

 yellowish or brownish spots, oblong, 0.3-0.5 mm. long, pulvinate, 

 rather tardily naked, cinnamon-brown; urediniospores fusiform, 

 16-19 by 42-58 ju, narrowed at both ends, provided with a hyaHne 

 beak at apex, 5-7 ju long; wall golden-brown, thin, i-i.5ju, 

 thickened above with a beak, the pores at or slightly above the 

 equator, 2. 



On Car ex Pseudo-Cyperus L., Leland, Michigan, August 29, 

 1913, /. C. Arthur. This highly distinctive rust, whose slender, 

 fusiform spores are very unlike those of any other cyperaceous 

 rust known to the writer, was found in an open marsh close to the 

 east shore of Lake Leelanau. Only a small infected area on two 

 or three leaves was secured. The host was in fruit, and its 

 determination has been made by Dr. Theo. Holm.
