Mr. J. Miers on the Caiyceracez. 351 
branch, its leaves, thus approximated, assume a campanular in- 
volucral form, being accreted at their base into a broad shallow 
cup supported upon a short stipe, with a border of foliaceous 
segments ; and it contains about seven distinct capitella, which 
are analogous to the short scapes, each bearing a monocephalous 
head, seen in each axil of the stem im the typical species, but in 
this instance all are brought close together by the depression of 
the stem ; each capitulum is supported upon a short stipe, and 
consists of an involucel of five to seven linear leaflets containing 
a solitary spined achzenium in the centre, surrounded by seven 
or eight other achznia which are quite unarmed, and all are 
supported by a small epaleaceous receptacle. Thus considered, 
the plant exhibits all the peculiar and essential characters of 
Anomocarpus. 
I have united with this genus the Leucocera of Turezaninow, 
founded upon the Boopis leucanthema of Péppig, which agrees 
with Anomocarpus in all essential respects, except that the re-~ 
ceptacle is more convex, almost conical, and charged with per- 
sistent palez, after all the achznia have fallen off, as in Boopis. 
These characters are hardly sufficient to claim a distinct generic 
rank for Leucocera—a name that would have been ill applied, as 
the spines of the achznia are of a yellowish brown.colour. The 
great difference in the form of the achznia was scarcely recog- 
nized by Turezaninow—a feature better characterized by the 
name Anomocarpus, which I had long previously employed for 
the more legitimate species.
