The ninth species has a shrubby erect stalk 

 about five feet high, hairy and armed with short, 

 broad, strong thorns, which are white, standing 

 on each side, almost opposite, or alternate : the 

 leaves live- or six-paired, with a strong midrib, 

 and between each pair two short strong spines, 

 pointing out each way : the leaflets extremely 

 narrowband very close: towards the upper part 

 of the stalk the flowers arc produced from the 

 sides on short peduncles ; they are collected 

 into 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 com- 

 monlv live or six joined together at the base: 

 they separate at each articulation, leaving the 

 two side membranes or borders standing : the 

 seeds, which are compressed and square, drop 

 out from the joints of the pods, which arc 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 scat- 

 tered 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-com- 

 pressed, 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 pvramidal 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 verv singular, subaxillary and connate at the 

 base, resembling the horns of oxen; brown, shin- 

 ing, 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 appearance, ft is a native of Carthagcna, 

 flowering in June and July, and ripening seeds 

 in September. 



The thirteenth species has the branches angu- 

 lar, smooth, with a brown bark : the leaves 

 sometimes two from the axil of the spines : 

 jiartial four- or five-paired, inner shorter, with 



M I M 



leaflets from five- to seven-paired, outer eight-t(j 

 eleven-paired : leaflets linear, acute, smooth : 

 the spines in pairs white, purple at the tip : the 

 flowers in a globular head, axillary and solitary, 

 first sessile, then peduncled, shorter than the 

 leaves : the legumes compressed, and attenuated 

 at the base. It is a native of the East and West 

 Indies, &c. 



The fourteenth has the flowers many-stamen- 

 ed, very fragrant, yellow, in sessile heads : the 

 petioles have a gland below the leaflets : the le- 

 gumes are fusiform. On account of the sweet- 

 ness of its flowers, ii has been dispersed through 

 most parts of Europe. It is brought bv the 

 Italian gardeners, who bring over Orange-trees, 

 &c. in young plants, under the name of Gazia. 

 It is a native of Saint Domingo, flowering from 

 June to August. 



The fifteenth species is a tree which arrives at 

 a large size in countries where it grows naturally, 

 but in this climate is rarely seen more than eight 

 or ten feet high : it has the habit of the four- 

 teenth sort ; differing in having no callous dots 

 upon the branches : the bark is purple : the 

 spines in pairs, and longer than those of the 

 fourteenth : the branches purple, even : the par- 

 tial leaves about five pairs ; between two pairs 

 of the outer ones a gland is inserted into the 

 common petiole : the legumes necklace-shaped, 

 compressed: the joints roundish-rhomb-rshaped : 

 flowers manv-stamencd, in peduncled heads. It 

 is a native of Egypt and Arabia. It is the tree 

 which yields the Gum Arabic. 



The sixteenth has leaves simple, linear, and 

 pungent or hard and pricklv at the end, and 

 growing in whorls six or seven together ; hut it 

 has dissimilar leaves, and the primordial ones, 

 or two or three first leaves which appear on the 

 seedling plants, arebipinnate. It is a native of 

 New South Wales, flowering from March to 

 May. 



According to Mr. Curtis, it is some years in 

 arriving at its flowering state. 



The seventeenth is a lofty tree, with an up- 

 right smooth trunk, covered with an ash-colour- 

 ed bark : the branches diverging, bent down, 

 smooth : the partial leaves twelve-paired : the 

 universal petiole round, striated, ferruginous- 

 pubescent : partial petioles also ferruginous : the 

 elands roundish, concave, between the petioles: 

 the scalelets bifid, minute, at the base of the 

 partial petioles: pinnas sixteen- or eighteen-pair- 

 ed, halved, subscssile, acute, entire, smooth : 

 the spikes peduncled, subglobular, composed of 

 aggregate, sessile, white flowers : the peduncles 

 axillary, and slender: the seeds spherical, shin- 

 ing black. .It is a native of Jamaica, where it 

 is called Mountain or Wild Tamarind Tree.
