ACAGIA. 



A. haftulata. Little Halberd-leaved Acacia Leaves 



deltoid, fpinous-pointed, roughilh ; their upper angle glan- 

 dular. Stipulas briltle-fhaped, permanent. Branches rough. 

 Flowers in folitary axillary heads. — Gathered near King 

 George's found, on the fouth-weft coaft of New Holland, 

 by Mr. Menzies, to whom we are obliged for a fpecimen. 

 This remarkable new fpecies is evidently allied to the two 

 laft -mentioned, though abundantly diftindl from both. The 

 {hruhhyjlem bears numerous, ereft, round, rough, wand-like 

 branches, befet with innumerable, fpreading, vertical leaves, 

 about a quarter of an inch long, fmgle-ribbed, unequally 

 deltoid, with an elongated fpinous point, thick-edged, rough 

 with minute points ; their lower angle either rounded or 

 fomewhat toothed ; the upper more prominent, and tipped 

 with a gland. Stipulas flender, ereft, in pairs at the bafe of 

 each leaf. Flowers three or four in each of the little ftalked 

 heads, which are very numerous all along the branches. 



A. deciplens. Paradoxical Acacia. Br. in Ait. n. 17. 

 Curt. Mag. t. 1745. ( Mimofa decipiens ; Konig in Ann. 

 of Bot. V. I. 366. t. 8. Adiantum truncatum ; Burm. 

 Ind. 235. t. 66. f. 4. Linn. Syft. Veg. ed. 13. 790.) — 

 Leaves triangular-wedgelhaped, fpinous-pointed, fmooth ; 

 their upper angle glandular. Stipulas briftle-fhaped, deci- 

 duous. Branches fmqoth. Flowers in folitary axillary 



heads Gathered by Mr. Menzies on the fouth-weft coaft 



of New Holland, and not on the weft fide of North 

 America, as mentioned in the Annals of Botany. Seeds 

 were fent to Kew in 1803, by Mr. Good, and the plant 

 is marked by Mr. Alton as a green-houfe Ihrub, flowering 

 from March to June. Its hiftory is certainly curious ; 

 fpecimens without flowers having been taken by profeflbr 

 Burmann, who mifled Linnaeus, for an yfrliantuni, which 

 error was detected by the late Mr. Dryander, on feeing 

 Mr. Menzies's fpecimens. Thofe of Burmann were reported 

 to have come from Java, in which there may be a further 

 miilake. At any rate this plant is nearly related to our laft- 

 defcribed, and grows in the fame country. The leaves differ 

 in being larger, half an inch to an inch long, ereft, and dif- 

 ferently (haped, their inner, or upper, glandular angle being 

 greatly extended, wliile the lower or rounded angle, feen in 

 yi. hajlulata, is wanting. The Jlo-wers are more numerous, 

 from feven to ten, in each round head. 



K. biflora. Two-flowered Acacia. Br. in Ait. n. 1 8. — 

 " Leaves triangular ; the outer angle fpinous ; inner glan- 

 dular. Stipulas briftle-fhaped and fpinous, permanent. 

 Young branches downy. Heads two-flowered." — Obferved 

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

 from whence it was fent to Kew by Mr. Good, in 1803. 

 A green-houfe flirub, flowering from March to June. We 

 have feen no fpecimens. 



A. armata. Simple-leaved prickly Acacia. Br. in Ait. 

 n. 19. Curt. Mag. t. 1653. — " Leaves oblong, halved, 

 fmooth, with a fmall point ; their folitary rib near and parallel 

 to the fomewhat abrupt interior margin. Stipulas fpinous. 

 Heads folitary, globofe. Branches hairy." — Obferved by 

 Mr. Brown, on the fouth coaft of New HoUand. Sent to 

 Kew, by Mr. Good, in 1803. A green-houfe fhrub, flower- 

 ing from April to June. Leaves dark green, an inch long, 

 feilile. Flowers yellow, numerous. 



A. alata. Wing-ftalked Acacia. Br. in Ait. n. 20 — - 

 " Stem winged on two fides. Leaves decurrent, fmgle- 

 ribbed, tipped with a fmall fpine ; their inner margin with 

 one glandular tooth. Stipulas fpinous. Heads ftalked, 

 moftly folitary." — Gatheredby Mr. Brown, on the fouth-weft 

 coaft of New Holland, from whence feeds were fent to Kew, 

 by Mr. Good, in 1803. This is hkewife a (hrubby green, 

 houfe plant, flowering from April to July. 



Vol. XXXIX, 



Seifl. 2. Leaves conjugate, pinnate. Seven fpecies in Wilf- 

 denow, to which one of Mr. Brown's is to be added from 

 Hort. Ketv. The Prodromus of this able author, when 

 completed, vrill probably fumifli more New Holland fpecies 

 to this feftion. 



A. xylocarpa. Wooden-fruited Acacia. Willd. n. 17. 



(Mimofa xylocarpa; Roxb. Corom. v. 1. 68. t. 100.) 



Leaves conjugate, pinnate ; leaflets four pair, ovate-oblong, 

 acute. Heads globofe, many-flowered, lateral, ftalked, in 

 pairs — Native of the mountainous parts of the Circars of 

 Hindooftan,^ cafting its leaves during the cold feafon, and 

 flowering when the hot weather begins. This is one of the 

 largeft trees of this genus or any of its allies ; the timber 

 very hard, of a chocolate colour towards the centre, and much 

 efteemed for purpofes where hardnefs, toughnefs, and dura- 

 bility, are requifite, as in ploughs, the natives feldom ufing 

 iron in that implement. The leaves are large, fmooth, paler 

 beneath, confifting of two divilions, or wings, and thofe of 

 four pair of leafets each, except that the innermoft leaflet on 

 each fide, at the bottom, is wanting : the lower leaflets are 

 about two inches long ; the upper four or five. Heads of 

 flowers whitifli, the fize of a cherrj-, on fimple ftalks, two or 

 three inches in length. Corolla bell-fliaped, five-cleft. Sla- 

 mens ten. Legume only one from each head, ovate, com- 

 prefled, very large and woody, three or four inches long, the 

 ftalk becoming neceftarily greatly thickened. Seeds about 

 ten, oval, ranged near the lower edge, as large as kidney- 

 beans. 



A. pulchella. Zigzag Spiny Acacia. Br. in Ait. n. 22. 

 — " Leaves conjugate, pinnate, with a ftalked gland between 

 the wings, each of which has from five to feven pair of leaf- 

 lets. Stipulas fpinous, nearly equal to the leaves. Heads 

 fohtary. Branches zigzag." — Obferved by Mr. Brown, 

 on the fouth-weft coaft of New Holland, from whence feeds 

 were fent to Kew, in 1803, by Mr. Good. A green-honfe 

 ftirub, flowering from April to July. 



Seft. 3. Leaves doubly pinnate. Stem -without thorns. 

 Spikes oblong. Eleven fpecies in Willdenow, the laft of which, 

 A. Houjioni, we fliall remove to the following fedlion. 



A. muricata. Warty Acacia. Willd. n. 25. ( A. lati- 

 folia alopecuroides, flore albo ; Plum. Ic. 6. t. I!. Mimofa 

 muricata; Linn. Sp. PI. 1504.) — Thorns none. Leaves 

 doubly pinnate ; firft divifion of five pair ; fecond of many 

 pair ; leaflets abrupt. Spikes axillary, aggregate, nearly 

 cylindrical. Branches warty. — Gathered in South America, 

 or the Weft Indies, by Plumier, whofe figure is the only 

 authority for this fpecies. The brunches are round, and 

 warty, as well as the lower part of the Jloiver-JJalks, which 

 laft are evidently axillary, not, as Willdenow fays, termina'. 

 They are longer tlian the large compound leaves, and bear 

 four or five alternate denfe fpihes, on partial ftalks. Leaf- 

 lets numerous, crowded, elliptical, veiny, emarginate, about 

 a half or three-quarters of an inch long. Floivers numerous, 

 very fmall. Legumes feveral, fpreading, four or five inches 

 in length, linear, flat, veiny, wavy at the edges, with many 

 oval Hat feeds. 



A. pallida. Pale South-American Acacia. Willd. n. 26. 

 — " Thorns none. Leaves doubly pinnate ; firft dirifion of 

 two pair ; fecond of twelve pair ; leaflets linear, obtufe, 

 downy. Spikes thread-fhaped, much longer than the leaves." 

 — Gathered by Humboldt and Bonpland, in South America. 

 Branches round, warty, divaricated. Leajets obtufe at each 

 end, fometimes but ten pair ; clothed fparingly on the 

 upper fide, more denfely on the under, with fine pubefcence ; 

 the edges fringed. There is a cup-(haped feffile gland be- 

 tween the fecondary divifions of each leaf (indications of 

 which appear likewife in Plumier's plate of the foregoing).
