REFERENCE TO THE PLATE.
1. The keel.
2. The chives and pointal,
3. Seed-bud and pointal.
T H I S new and very ornamental species is remarkable for having the under lip of the calyx often undrvided,
and every part of the plant up to the blossom covered with shining close-pressed hairs : nor are
they entirely wanting on the blossom ; on the lower part of the keel they are very conspicuous, hanging
downwards like a little beard. A groove with a fringe on each side runs also along the upper side of
the style towards the summit. Two thread-shaped silky stipules rise at the base of every leaf-stalk,
and, being reflected backwards, closely embrace the stem. A solitary stipule also rises at the base of
each flower-stalk, and two where it unites with the calyx : but these, from their singular situation,
must perhaps be considered as bracteas.
We were favoured with the specimens in November from Lord Valentia's gardens at Arley, along
with the Plectranthus barbata. His Lordship received the seeds last year from Di'. Roxburgh in India^
by the name of Crotalaria tetragona. The plant appears to be shrubby. No account of the species
has before been published. Its place in the genus is near to the Crotalaria juncea figured in our sixth
volume.
