fusiformibus vix compressis 7—9-nerviis hirtellis coronula 
integra sepius obsoleta superatis.— Margin of woods and 
thickets, in sterile soil, Comale Creek and near New Braun- 
fels (also 628.) April to June. A summer state, very much 
branched and with smaller capituli, was gathered in Western 
Texas by Mr. Wright. The plant has much the aspect of 
Bellis integrifolia, though the heads are rather smaller, and it 
_ branches diffusely in the same way, the branches terminated 
by single capituli.— The type of the genus Keerlia must be 
K. ramosa, DC., a Mexican plant collected by Keerl himself, 
and with which the present plant appears to be a true con- 
gener. K. linearifolia, DC. is thought to have yellow rays, 
which leaves its position doubtful. K. skirrobasis, DC., and 
of Delessert’s as well as of Hooker’s figure, is doubtless Leu- 
copsidium Arkansanum, DC., the Egletes Arkansana, Nutt., 
as I have already remarked in Proceed. Amer. Acad. l. ¢., 
and in Plante Fendleriane, p. 71. ‘The genus, as it thus 
stands, takes the place in this country of Brachycome, from 
which; as well as from Bellis, it is well distinguished by its flat 
receptacle. Mr. Lindheimer’s recent collection enables us to 
add another Texan species, of a peculiar aspect, and remark- 
able for its fewer-flowered heads, its flattened ray-achenia, 
and entirely sterile disk,! viz.
