the plant from V. ovata Niitt., with which it is always confounded. 

 Both species have the first three or four leaves oval and entire 

 or merely crenate, but before flowering, V. ovata puts forth its 

 characteristic strongly pubescent or even villous foliage, the regu- 

 larly shaped, almost entire, ovate-elliptical leaves never becom- 

 ing so elongated as to exceed either flowering or fruiting scape. 



Viola ovata Nuttall is I'', ciliata of Muhlenberg's Catalogue,* 

 well described and differentiated afterward by Darlington and 

 other writers and retained by Torrey and Gray as a variety of 

 sagittata. The plant which I last year described as another va- 

 riety of sa(jittata, under the name of Hicksu,f is much closer to 

 ovata tlian to tlie true sagittata as now understood, and I take 

 this opportunity of indicating its transfer, retaining it under the 

 varietal name. Dr. Robinson, in the Synoptical Flora above 

 quoted, J remarks in connection witli this form that the recurved 

 fruiting peduncles and distinctly mottled seeds "are not infre- 

 quently associated with quite different foliage." However this 

 may be, specimens have been sent to Prof. C. F. Wheeler, of 

 Michigan, and to Dr. T. J. W. Burgess, of Canada, both of whom 

 have admitted it to be distinct from Avhat they are accustomed 

 to regard as typical sagittata. We have it in the National Her- 

 Ijarium from Pennsylvania and from Sussex county. New Jer- 

 sey, in addition to the original localit}^ near Pierce's Mill, in the 

 District of Columbia. 



Pursh's Viola dentata, here reinstated, is a plant to which my 

 attention was called by Dr. Britton some time ago as a species 

 Tof marked validity. The leaves in this plant are glabrous and 

 somewhat flaccid, deltoid-cordate, or even panduriform in out- 

 line, irregularly crenate, and in general so unlike those of the 

 ordinary violets with which it is associated tliat it has been con- 

 sidered a hybrid. Le Conte [)ointed out tliese characters, under 

 his name of eiiiargiiiata, sixteen years after Pursh's original pub- 

 lication. The plant is mainly of southern range. A t\q)ical 

 specimen of it, collected by Dr. John K. Small in northern Geor- 

 gia in 1S05, is to be found in tlie herl)arium of Columbia Uni- 

 versity. In the National Herbarium the species is represented 

 by a ])lant found in the District of Columbia 1\y Dr. Yasey.
