274 BROOKLYN BOTANIC GARDEN MEMOIRS 
Tranzschel (Trans. Bot. Acad. St. Petersb. 11: 67-69. 1905) was 
the first to culture this species showing that aecia occur on Anemone. 
In America Arthur (Jour. Myc. 12: 19. 1906; 13: 199. 1907) 
has shown that the aecia on Hepatica common in the eastern United 
States are genetically connected.

This species differs from U. Limonu in the shorter, broader telio- 
spores and the short mostly deciduous pedicel. The first collection 
mentioned bears aecia accompanied by uredinia, the second, uredinia 
and telia only. The rust is abundant on a cliff near the seashore. 
So far as we are aware this is the first record of this species in America. 
182. Uromyces Beckmanniae sp. nov. 
O and I. Pyenia and aecia unknown. 
II. Uredinia amphigenous, scattered, elliptical, 0.5—-0.8 mm. long, 
soon naked, pulverulent, cinnamon brown, ruptured epidermis notice- 
able; paraphyses none; urediniospores globoid or broadly ellipsoid, 
19-24 by 23-30 uw, wall colorless or pale yellow, 2—2.5 uw thick, finely 
verrucose-echinulate, pores 8-10, scattered. 
Ill. Telia amphigenous and culmicolous, scattered or crowded, 
oblong, 0.4-0.7 mm. across, often confluent to form crusts or lines, 
tardily naked, blackish brown; teliospores obovoid or ellipsoid, angular, 
20-26 by 29-40 wu, apex rounded or angular, narrowed below; wall 
chestnut brown, I-2 yu thick, smooth, but showing distinct longi- 
tudinal ridges, apex thickened, 3-6 yu, pedicel colorless or slightly 
tinted next to the spore, equalling the spore or usually deciduous.
