(type, in Gray Herb.). This plant, distributed as Calyptrocarpus tam- 
picanus Small, differs markedly from that species in its spatulate- 
obovate leaves, larger closely sessile heads, and especially in its involucral 
scales. These are dorsally nearly glabrous but on the edges conspicu- 
ously ciliate, while in Calyptocarpus vialis Less. (Oligogyne tampicana 
DC., Calyptrocarpus tampicana Small) the condition is reversed, that is 
to say the involucral scales are dorsally strigose-pubescent but the 
margin nearly or quite free from ciliation. The discovery of a second 
and clearly distinct species of the hitherto monotypic Calyptocarpus 1s 
of interest. From the weedlike nature and wide distribution of its 
exano-Mexican congener, there must be some doubt whether the 
plant here described will prove really indigenous in its Alabama habitat, 
.or whether it may not ultimately be found to be an introduction from 
some other region. .
