tures to revert to a vegetative condition. A detailed comparison of these 

 different grasses showing the anomaly would make an interesting study. 



3. Sex in the sporophyte of Eragrostis hypnoides (Lam.) B.S.P. — 

 This species, which is a prominent part of the floras of muddy sand- 

 bars in late summer, is generally described as dioecious, and as such it 

 was thought to offer promising material for experimental work. How- 

 ever, an examination of several hundred specimens from thi'ee localities 

 in Indiana, and one in Georgia, showed not a single imperfect-flowered 

 specimen. In the variety capitata of this species there is said to be a 

 pronounced difference between the staminate and pistillate spikelets, 

 but no specimens of this have been available for examination. 



Duplicates of the specimens of Paspalum and Ei'agrostis upon which 

 these notes are based were identified by A. S. Hitchcock.
