The seventh rises with upright branching stalks six or seven feel 

 high, becoming woody towards the root, with callous dots dispersed 

 upon it, but not perennial (at least they are not so here in any situa- 

 tion, the plants always decaying in winter) ; they are smooth, and 

 the leaves are composed of four or five pairs of long winged lobes, 

 which have about twenty pairs of small leaves ranged along the mid- 

 rib; are smooth and rounded at their points, of a full green on their 

 upper side, but pale on their under: these small leaves contract 

 themselves together on their being touched, but the foot-stalks do 

 not decline at the same time, as those do which are titled Humble 

 Plants; it is therefore called the Sensitive Plant by way of distinc- 

 tion: the flowers are produced upon long foot-stalks, which come 

 out from the wings of the leaves, and are disposed in globular heads 

 which nod downward, are yellow; and all those which have petals 

 have ten stamina in each, but those situated round the border have 

 neither petals nor stamina; those on the upper part of the spike are 

 succeeded by pods an inch and a half long, and a quarter of an inch 

 broad, which change to a dark brown when ripe, inclosing three or 

 four compressed, shining, black seeds. It is probably a native of 

 America. 



The eighth species has the stems seldom more than two feet and a 

 half high, and smooth: the leaves are composed of three or four pin- 

 nas, which are shorter, and the leaflets much narrower than in the first 

 and seventh sorts; the heads of the flowers are smaller, being made 

 up of many long white filaments, forming altogether a round head, 

 and the pods longer and narrower, an inch long, and a quarter of an 

 inch broad, with a round protuberance at each seed. Jt grows na- 

 turally in all the islands of the West Indies, where it has its name 

 from the leaves not contracting on being touched. 



The ninth species has a shrubby erect stalk about five feet high, 

 hairy and armed with short, broad, strong thorns, which are while, 

 standing on each side, almost opposite, or alternate: the leaves five 

 or six-paired, with a strong midrib, and between each pair two short 

 strong spines, pointing out each way: the leaflets extremely narrow 

 and very close: towards the upper part of the stalk the flowers are
