the wings two pairs, about an inch asunder, short: the leaflets nai- 

 row, not very close: the peduncles axillary, sustaining a small globu- 

 lar head of purple flowers: the legumes four-cornered, two inches 

 long, four-celled, four-valved; containing several angular seeds in 

 each cell. It was found at La Vera Cruz. 



The fourth species rises with a slender woody stalk, seven or eight 

 feet high, armed with short recurved thorns: the leaves grow upon 

 long footstalks which are prickly, each sustaining two pairs of wings; 

 the outer pair has two lobes which join at their base, and arc rounded 

 on the outside, but straight on the inner edges, shaped like a pair of 

 sheep-shears; they are much larger than the inner, are almost two 

 inches long, and one inch broad in the middle: from the place 

 where these are inserted into the stalk, come out small branches, 

 which have three or four globular heads of pale purplish flowers 

 coming out from the side, on short peduncles: and the principal 

 stalk has many of those heads of flowers on the upper part for more 

 than a foot in length; and this, as also the branches, is terminated 

 by similar heads of flowers: the pods are broad, flat, jointed, opening 

 by two valves, containing one, two, or three compressed orbicular 

 seeds: the leaves move but slowly when touched, but the foot-stalks 

 fall when they are pressed very hard. It is a native of Brazil. 



The fifth has the roots composed of many hairy fibres, which sit 

 close together, from which come out several woody stalks, which 

 decline towards the ground, unless they are supported; they are 

 armed with short recurved spines, and have winged or pinnate 

 leaves, composed of four, and sometimes five pinnas, whose bases 

 join at a point, where they are inserted into the foot-stalk, spreading 

 upwards like the fingers of a hand : the flowers from the axils, on 

 short peduncles, collected in small globular heads, of a yellow co- 

 lour: the pods short, flat, jointed, in close clusters; almost covered 

 with stinging hairy covers. It is a native of Brazil. 



The sixth species has the spike roundish, nodding: the flowers 

 ten-stamened, and yellow; the lower ones of the spike without sta- 

 mens or petals. It is a native of the West Indies, flowering in July 

 and August.
