Smaller and more slender than Orobus luteus, figured at
Tab. 115, from which it also differs in its broader, nearly
smooth leaflets, green on both sides, broader stipules, and
shorter calyx, with the lateral pair of teeth considerably
shorter than in that species. The flowers are of a deeper
yellow, inclining to orange. The ovarmm is stalled, but m
the stigma we have not remarked any matenffi difference, it
being bearded along the upper surface, as m O. luteus.
Our drawing was taken in May last, at the Nurseries of
Messrs. Whitley, Brames, and Milne, at Fulham, bmng the
only collection in which we have observed the species.
The plant is perennial, requires a loamy soil, and may
be increased both by parting the roots, and by seeds.
It is a native of the western regions of Caucasus, whei e
it was originally discovered by M. Steven. It is essentially
distinguished from the Orobus croceus of Desfontaines by its
smooth leaves, attenuated at both ends, and by the very
unequal teeth of its calyx.
