Jussieu has maintained Tourneforte's division of this 
very natural group into Cistus and HELIANTHEMUM chiefly 
upon the ground of the difference іш the number of the 
valves in the capsules of each, and in the substance and 
extent of the septa or partitions of the same. But in the 
way he has characterized the two genera, our plant would 
not find a place in either; to the first he gives an equal 
calyx, to the last a 3-valved capsule. In our view the group 
is one of those, which, although numerous, are most ad- 
vantageously kept under one generic denomination. By 
dispersing such under new appellations, one use of a gene- 
ric name, viz. the bringing a well-assorted series of distinct 
species into our idea by a single word, is nearly defeated 
to spare a few terms in the definition of the technical 
Character. 
The present species, perhaps the most ornamental of the
