projected tubercle armed at the base with a pair of spinescent 
stipules: leaflets four or sometimes five pair, obcordate or 
obovate, with a minute mucro, covered with a silky pubeseence 
on both sides. Peduncles growing from the same tubercle 
as the leaves, sometimes singly, more generally two, and 
now and then three together, shorter than the flower, villous, 
jointed, and having a pair of small bractes. Calyx subcy- 
inline, gibbous at the base: limb five-toothed, the two upper — 
teeth very small and approximate. Corolla papilionaceous : 
vexillum cordate with the sides reflected, closed at the base : 
ale of the same length, lanceolate : carina somewhat shorter, — 
boat-shaped, with its petals united towards the tip. Stamens 
diadelphous, 1—9. Germen flattened-cylindric, very smooth : 
style ascendent: stigma simple. . 
If Rosinia Caragana and Aliagana are to be held as 
distinct species, then this must be considered as different 
from both, and may retain the name of arenaria. But we 
are inclined to regard them all three as varieties of the same 
species ; as Pauas asserts that the low shrubby kind, in a 
richer soil, will become arborescent ; the number and form © 
of the leaflets seem very subject to vary ; in PAuias’s figures, 
referred to by L’Herrrier, they are obcordate ;_ in his own, 
oval ; but in his description, said to be sometimes obovate or 
wedge-shaped. — . Slee
