[November, 



50-80// long. — On stems, leaves and pods of Cassia nictitans, Au- 

 burn, Ala., Geo. F. Atkinson; Stark vi lie, Miss., S. M. Tracy. 



Frequently there is very little of the fungus on the leaves, it being 

 chiefly caulicolous. Occasionally it is abundant also on the leaves, but 

 the sori are comparatively small. Sometimes all the sori on the leaves 

 contain only uredospores, but again teleutospores as well. 



I have had an opportunity of comparing this species with R. stidica, 

 Berk. & Br., n. 554 Myc. Univ., R. glanduheformis Berk. & Cur., n. 

 1251 Myc. Univ., and R. Texanus Ell. & Galloway. 



I have also collected at Auburn, during the month of September, 

 1891 , R.glanduhej vr mis B. & C. on Tephrosia hispid u la 7mA Virginiana 

 and my assistant, Mr. B. M. Duggar, has collected it on Tephrosia 

 spicata. The specimens on Tephrosia Virginiana are of interest from 

 the fact that the fungus is very abundant on the stems, the sori being 

 longer and often confluent, presenting much the same appearance to 

 the unaided eye as Ravenelia Cassiaecola on Cassia nictitans. — Geo.

Cleistojramy in Polygonum acre. — Apropos of Mr.Meehan's discovery 

 of cleistogamy in Polygonum, I would record the observation of cleis- 

 togamous flowers on the same species, P. acre, at Knoxville, Tenn., on 

 the 24th of September. For the accompanying illustrations, showing 



\ 



the appearance of plants in question, I am indebted to Prof. Scribner. 

 I have searched for cleistogamic flowers on other species of Polygo- 

 num, but without success.— T. H. Kearney, Jr., University of Teti-
