JaNSONIA FORMOSA.

(1842), Gilbert (v. s.).

The nearest affinity of Jansonia is with Brachysema, R. Br., with 
which genus Mr. Kippist states that it agrees in its unguiculate 
petals, in the form and unusual length of the keel, in the extreme 
shortness of the standard, in its elongated filiform style, and in its 
shortly stalked villous germen, surrounded at the base by a minute 
fleshy ring ; but it is abundantly distinguished by its capitate inflo- 
rescence, by the remarkable inequality of its calycine segments, by 
the much greater length of the claws of its petals, and by the pau- 
city of its ovules, which do not appear to exceed six in number. 
Mr. Kippist also compares it with Leptosema, Benth., which is clearly 
distinguished by its bibracteolate calyx, composed of two nearly equal 
lips, the uppermost of which is very slightly bifid ; its scarcely un- 
guiculate vexillum ; its wings about equal in length to the keel ; the 
distinct inflexion of its carinal suture ; as well as by its inflorescence, 
that of Leptosema being a densely crowded raceme, while in Jansonia 
the flowers are perfectly sessile and arranged in a verticillate manner 
round a common axis, which is slightly prolonged beyond the point 
from whence the flowers spring in the form of a short mucro. 
The genus is dedicated to the memory of the late Joseph Janson, 
Esq., F.L.S. ; and the paper was accompanied with a drawing of the 
j)lant, comprising details of its parts of fructification.
