ACACIA. 



Footjlalks hairy. Spihes axiUary, folitary, tluree or four 

 inches long, being thricp the length of the leaves. Flowers 

 oppofite, of five/f/a/j. WillJenoiu. 



This feems much allied to the laft, but the fhape and 

 downinefs of the haflds, and the folitary /pikes, indicate a 

 fufficicnt difference.

 none. Leaves doubly pinnate ; firft dmfion of fix pair ; 

 fecond of fixteen pair ; leaflets linear, acute. Spikes thread- 

 (haped, in pairs."— Found by Mr. Bredemeyer at the Ca- 

 raccas, about the fandy banks of rivers. A Jhrub ten or 

 twelve feet high, with angular downy branches. Leaflets 

 fringed, from ffxteen to twenty-four pair. Footjlalks clothed 

 with hoary down ; the partial ones accompanied by an acute 

 intermediate gland. Spikes axillary, meafuring three or four 

 inches, generally rather longer than the leaves. Flowers 

 oppofite, white, fragrant. Calyx with four or five teeth. 

 Corolla in four or five deep fegments. Stamens twice as 

 many, and thrice as long. Wllldenow.

 pair ,■ leaflets elliptical, obtufe. Common footftalk with a 

 convex gland. Spikes thread-fhaped, axillary. — Obferved 

 by Aublet in Cayenne and Guiana, flowering in November, 

 and bearing ripe feeds in January and February. This is a 

 large tree, whofe trunk, thirty or forty feet high, is a foot or

 a httle leafy ftalked appendage. Legume linear-oblong, 

 flattifti, brown, fmooth, three or four inches in length, with 

 feveral feeds. 



A. lophantha more properly belongs to this feftion, though 

 placed in the next.

 Spikes globofe. Thirty -one fpecies in Willdenow, to which 

 we have three to add, befides A. Houjloni.

 " Without thorns, hairy. Leaves doubly pinnate ; firft 

 divifion of two pair ; fecond of two or three pair. Stipulas 

 nearly fetaceous, deciduous. Heads folitary." — Gathered 

 by Mr. Brown, on the fouth-weft coaft of New Holland ; 

 and feut to Kew, by Mr. Good, in 1803. A green-houfe 

 fhrub, flowering from March to June, of which we have not 

 feen either fpecimen or figure.

 (Mimofa nigricans ; LabiU. Nov. HoU. v. 2. 88. t. 238.)

 weft coaft of New Holland, from whence Mr. Good fent 

 feeds to Kew, in 1803. A green-houfe (Jirub, flowering 

 from May to July, faid to be about fix feet high in a wild

 doubly pinnate ; firft divifion of four pair ; fecond of ten 

 or twelve pair ; leaflets obtufe, the lowermoft very minute. 

 Heads panicled, terminal. — Native of the mountainous parts 

 of the coaft of Coromandel, flowering in the hot feafon. 

 The wood is hard, and equally ufeful with that of yt. xylo- 

 carpa. (See Seft. 2.) The leaves are a fpan long, with 

 uniform leajlets, an inch in length, glaucous beneath, very 

 unequal at their bafe. Flowers numerous, white, highly 

 fragrant, in numerous, aggregate, ftalked, globular heads.

 — Thorns none. Leaves doubly pinnate ; firft divifion of 

 feven pair ; fecond of feventeen pair ; leaflets halved, acute. 

 Heads axillary, ftalked. Legume contorted, tumid. Seeds 

 fpherical. — Native of fields and woods in Jamaica, where it 

 is called Wild Tamarind, and is one of the largeft trees of 

 that ifland. The wood, according to Sloane, is durable, 

 though foft and white. Leaves of numerous, fmall, dark-

 icenX-d Jlowers, whole corolla is reddifli, the Jlamens whitifli, 

 very long. Legume as if beaded, four or five inches long, 

 red ; its valves of a blood-red on the infide. Seeds globular, 

 of a ftiining black. This fpecies was cultivated by Miller, 

 but is now unknown in our gardens, nor are botanifts in 

 general well acquainted with it ; Forfljall and Thunberg 

 having given the name of Mimofa arborea to ttvo plants 

 very different from this, as well as from each other. 



A. Juliorijjin. Smooth Tree Acacia. Willd. n. 39. 

 Ait. n. 29. (Mimofa Julibriflin ; Scop. Infubr. v. i. 

 18. t. 8. Ait. ed. 2. v. 3. 440. M. arborea; Forfl{. 

 .(Egypt. -Arab. 177. Gmel. It. v. 3. 372. t. 40.) — Thorns 

 none. Leaves doubly pinnate ; firft divifion of about ten 

 pair ; fecond of many pair ; leaflets halved, obtufe with a 

 point. Heads lax, aggregate, terminal. I^egume flat, 



membranous, fmooth Native of the Levant. Forfliall faw 



it cultivated at Conftantinople, where it v/as called Djui 

 ibrzi?n, by the Turks ; which name, denominating a Jiliy 

 fio'wer, ill allufion to the ftamens, appears to be the origin 

 of the fpecific appellation chofen by Scopoh. We have 

 feen this fpecies as large as a common apple-tree, covered 

 with a profufion of bloffoms, in the open ground at Turin, 

 nor could any thing be more elegant or fplendid. In 

 England it is ufually treated as a green-houfe plant, and 

 flowers fparingly ; though it fucceeds well againft a wall, 

 with fome proteftion in winter. The leaves are large and 

 fpreading, of numerous leajlets, half an inch long, very 

 unequal in their two halves. Flowers lilac, with long 

 monadelphous Jlamens, forming moft beautiful tailels like 

 white filk. Legume half a foot long, thin, pale brown, 

 corrugated, unequal in breadth, with many fmall flattifh 

 feeds.
