D. C. legum. mem. xii. prod. 2. p. 445. Legume linear, twisted 

 or somewhat falcate ? Sterile filaments linear, and elongated ; 

 anthers of the fertile ones bearing a pedicellate gland at the 

 apex of each. Petals 5, distinct or joined ? Shrubs, having the 

 branches usually spinescent, with bipinnate pubescent leaves, bear- 

 ing from 5-10 pairs of pinnae, and each pinna bearing many pairs 

 of leaflets, furnished with glands between the pairs of pinnae, espe- 

 cially between the lower ones. Flowers disposed in oblong-cylin- 

 drical 2-coloured spikes, in consequence of the sterile stamens 

 being white or variously coloured, and the fertile ones yellow. 



14 D. DIVE'RGENS (Willd. spec. 4. p. 1048.) leaves with 8 

 pairs of pinnae, each pinna bearing 10-15 pairs of ciliated leaf- 

 lets ; spikes of flowers twin, pendulous, cylindrically obovate ; 

 legumes twisted. I? . S. Native of Abyssinia. Bruce, trav. 

 5. t. 61. 



Diverging Desmanthus. Fl. June, July. Clt. 1816. Shrub 

 3 to 6 feet. 



1:5 D. LEPTO'STACHYS (B.C. legum. mem. xii. prod. 2. p. 445.) 

 leaves with 8 pairs of pinnae, each pinna bearing 20-30 pairs of 

 ciliated leaflets, furnished with a stipitate gland between each pair 

 of pinnae ; petioles and peduncles hairy ; spikes of flowers usually 

 twin, cylindrical, shorter than the leaves. fj . S. Native of 

 Senegal and Sierra Leone. Sieb. pi. exsic. seneg. 47. Very 

 nearly allied to the preceding species, but differs from the plant 

 figured by Bruce, in the leaflets being more numerous, and in 

 the spikes of flowers being more slender, and not pendulous, 

 and, lastly, in the sterile filaments being filiform. 



Slender-spiked Desmanthus. Fl. July. Clt. 1825. Shrub 

 3 to 5 feet. 



16 D. CALLI'STACHYS (D. C. prod. 2. p. 445.) leaves with 5 

 pairs of pinnae, each pinna bearing about 20 pairs of leaflets ; 

 petioles and peduncles hairy ; glands on the petiole sessile ; 

 spikes solitary, cylindrical, erect. (7 . S. Native country un- 

 known. Spikes of flowers rose-coloured at the bottom, but yel- 

 low at the top. Sterile filaments linear. Anthers furnished with 

 a black gland each. The specimens of this plant were collected 

 in the gardens of Teneriffe. 



Beautiful-spiked Desmanthus. Fl. June, July. Clt. 1824. 

 Shrub 2 to 4 feet. 



17 D. TRICHO'STACHYS (D. C. legum. mem. xii. t. 67.) leaves 

 with 10 pairs of pinnae, each pinna bearing 20 pairs of ciliated 

 leaflets ; petioles and peduncles puberulons ; glands on the pe- 

 tioles pedicellate ; spikes cylindrical, erect, interrupted at the 

 base, rather longer than the leaves. J; . S. Native of Senegal. 

 Mimosa bicolor, Bacle in litt. 1820. Mimosa varia, Perr. in 

 litt. 1825. Branches unarmed according to the specimen. 

 Spikes 2 inches long. Sterile filaments very long, and hair- 

 formed. 



Hair-spiked Desmanthus. Shrub 3 to 4 feet. 



18 D. CINE'REUS (Willd. spec. 4. p. 1048.) leaves with 8-10 

 pairs of pinnae, each pinna bearing about 12-15 pairs of ciliated 

 leaflets ; petioles pubescent ; spikes of flowers solitary, nodding, 

 rather shorter than the leaves ; corolla gamopetalous, 5-toothed ; 

 legume linear, falcate, somewhat transversely loculate inside. 

 Jj . S. Native of the East Indies. Mimosa cinerea, Lin. spec. 

 1505. Roxb. cor. 2. t. 174. Burn), zeyl. t. 2. Spikes rose- 

 coloured at the bottom and yellow at the apex. Branches white, 

 when young pubescent. 



Cinereous Desmanthus. Fl. June, July. Clt. 1739. Shrub 

 6 to 7 feet. 



19 D. NU TANS (D. C. prod. 2. p. 446 ) branches spiny, when 

 young clothed with hairy tomentum ; leaves with 10 pairs of 

 pinnae, each pinna bearing 20-25 pairs of ciliated leaflets ; pe- 

 tioles villous ; spikes pedunculate, rather shorter than the leaves, 

 nodding ; flowers decandrous, the filaments in the lower ones 

 castrate and petaloid. T? . S. Native of Senegal. Mim6sa 



nutans, Pers. ench. 2. p. 115. This is perhaps the same as D. 

 leptdslachys, but differs in the spines being straight, spreading, 

 simple, hairy, but at length becoming glabrous. 



Nodding-spiked Desmanthus. Shrub 3 to 4 feet. 



Cult. A mixture of peat, loam, and sand suits the species of 

 this genus, and young cuttings root readily if planted in a pot of 

 sand, with a bell-glass placed over them. The kinds belonging 

 to section 1. Neptunia, being aquatics with sensitive leaves, 

 should be grown in tubs or large pans, with 4 or 5 inches of 

 mould in the bottom, and filled up with water. The tubs or 

 pans should be placed in a warm situation in a stove, or in a hot- 

 bed in summer, where the plants will thrive and produce seeds. 



CCXXX. ADENANTHE'RA (from V, aden, a gland, 

 and avQtjpa, anthera, an anther ; in reference to the anthers, 

 which are terminated by a deciduous, pedicellate gland each). 

 Lin. gen. no. 526. Lam. ill. t. 334. D. C. prod. 2. p. 446. 



LIN. SYST. Decandria, Monogynia. Flowers hermaphro- 

 dite. Calyx 5-toothed. Petals 5, lanceolate, sessile. Stamens 

 10. Anthers terminated by a pedicellate, deciduous gland 

 each. Legume compressed, linear, membranous, transversely 

 many-celled inside, somewhat swollen above the seeds, des- 

 titute of pulp. Trees or shrubs, with bipinnate leaves and 

 racemose spikes of flowers. This genus is related to Cassia, 

 according to Bronn. diss. p. 130. but differs in the petals beinsi 

 valvate in aestivation. 



1 A. PAVONI V NA (Lin. spec. 553.) leaflets oval, obtuse, gla- 

 brous on both surfaces ; legumes rather falcate. T? . S. Native 

 of the East Indies. Jacq. coll. 4. p. 212. t. 23. Rumph. amb. 

 3. t. 109. Flowers white and yellow mixed. Legume falcate, 

 10-12-seeded. Seeds highly polished, of a vivid scarlet colour, 

 with a circular streak in the middle on each side. This is one 

 of the largest trees in the East Indies, and its timber is much 

 valued on account of its solidity. The natives use the powder 

 of the leaves in their ceremonies. The seeds, besides being 

 eaten by the common people, are of great use to jewellers and 

 goldsmiths, on account of their equality, for weights, each of 

 them weighing 4 grains ; they also make a cement by beating 

 them up with borax.
