produced from the sides on short peduncles; they are collected iato 

 globular heads, and are of a bright purple colour: the stalks are also 

 terminated by smaller heads of the like flowers: the pods flat, jointed, 

 about two inches long, and a quarter of an inch broad, spreading 

 like rays, there being commonly five or six joined together at the 

 base: they separate at each articulation, leaving the two side mem- 

 branes or borders standing: the seeds, which are compressed and 

 square, drop out from the joints of the pods, which are hairy at first, 

 but as they ripen become smooth : the petioles do not fall on being 

 touched, but the leaflets close up. It is a native of La Vera Cruz. 



The tenth has the stem recurved, prickles scattered over it in 

 pairs: the leaves commonly six-paired, with many paired pinnas: 

 on the universal petioles there are recurved prickles between each of 

 the partial ones; and there is a straight upright prickle which is 

 longer, between each pair of the partial ones, in place of a gland : 

 the heads are globular: the legumes membranaceous-compressed, 

 jointed, rugged. It is a native of South America. 



The eleventh species has the spikes globular, large, peduncled: 

 the flowers white, apetalous, ten-stamened : the legumes long, flat. 

 It flowers in April, and the seeds ripen in autumn; found at La 

 Vera Cruz. 



The twelfth is a tree which seldom exceeds twelve feet in height: 

 it has numerous branches forming a pyramidal figure: the leaves are 

 small ; the flowers are small, yellow, and void of scent, in a close 

 cylindrical spike, an inch and a half long: the legumes coriaceous, 

 containing a buttery pulp, in which the seeds are rolled up: the 

 spines are very singular, subaxillary and connate at the base, re- 

 sembling the horns of oxen ; brown, shining, hollow, and the longest 

 more than five inches in length; they are all over the tree; and when 

 the pods are ripe and the leaves fallen, they have a singular appear- 

 ance. It is a native of Carthagena, flowering in June and July, and 

 ripening seeds in September. 



The thirteenth species has the branches angular, smooth, with a 

 brown bark: the leaves sometimes two from the axil of the spines: 

 partial four or five-paired, inner shorter, with leaflets from five to
