Spec. Char., §c. Leaves dotted from glands beneath, 3—5-lobed. Racemes 
loose. Bracteas minute, subulate or obtuse, much shorter than the pedi- 
cels. Petals oblong. Calyx campanulate, with reflexed segments. Flowers 
whitish, or yellowish green. Calyx often of a rich brownish red colour, 
or pink. Stamens sometimes more than 5, in which case there are fewer 
petals ; so that when there are 10 stamens there are no petals. This 
change of petals into stamens is just the reverse of the process by which 
single flowers become double; and it is the only fact of the kind which has 
hitherto been observed. Stigmas bifid. Berries globose, black, glandular. 
(Don’s Mill.) A shrub with smoothish branches, strong-smelling leaves.
