LEGUMINOSjE. 
307 
minute ovate braeteole. Calyx small, 5-dentate, with the teeth 
rather indistinct. Corolla more than twice the length of the 
calyx, 5-fid, with the teeth acute. Filaments capillary, yellow, 
matted, three times the length of the corolla. Legumes toru- 
lose, twisted in a spiral manner, of a red colour : seeds 5-6, 
black, shining, roundish, compressed, half-buried in a snow- 
white fleshy arillus-like pellicle. 
The specific designation, unguis-cati, is given from the curved 
form of the thorns with which the tree is armed. Browne calls 
it the black-bead shrub ; and from others it receives the names 
of Barbary -thorn and Nephritic-tree. Barham tells us, that it is 
a sovereign remedy for stone, gravel, and other urinary com- 
plaints, and also for obstruction of the liver and spleen. We 
are informed that it was first planted in the Island by a Span- 
ish Bishop, who, in expatiating on the virtues of the plant, 
deduced that it must be useful in nephritic complaints, from the 
shape of the seeds resembling that of the kidney, and the white 
arillus corresponding to the fat in which the gland is imbedded. 
The bark is the part that is made use of, and Barham states, 
that in his time it was in such general use, that it was rare to 
meet with a tree that had not been barked. The decoction is 
of a red colour, is very astringent, and has the reputation of 
acting as a diuretic. It has been employed externally as a 
lotion and injection in cases of relaxation of the parts. It is 
supposed that this plant was introduced by the Spaniards, as it 
is confined to the neighbourhood of Spanish-Town, and has not 
been met with in any other part of the Island.
