Syn. Mimosa ferruginea, Eoxb. Fl. Iiid. ii. 561. Vern. Kaiger, Panch 

 Mehals. 



A large tree, with rough, dark-coloured bark; glabrous, armed with 

 twin, short, infra-stipular prickles, rarely unarmed. Common petiole 3-6 

 in. long, common and secondary petioles with thickened base; glands 

 small, circular or linear at the base of the upper pairs of pinnae, and 1 be- 

 low the pinnae ; leaflets oblong-linear, grey or glaucous, 15-30 pair; 

 pinnae 4-6 pair, 2-3 in. long. Flowers pale yellow, in lax, axillary spikes, 

 4-5 in. long, the spikes often numerous, and sub-paniculate near the ends 

 of branches. Calyx about J the length of corolla, with short triangular 

 teeth. Pods glabrous, light or dark brown, 3-4 in. long, flat, thin, inde- 

 hiscent, nearly 1 in. broad. 



South India, the Konkan, Mundlaisir, and forests of the Panch Mehals in 

 Guzerat. Fr. Jan., Feb. Bark strongly astringent, used, like that of leuco- 

 phloea, in the distillation of arrack (Bedd.) Heartwood reddish brown. 



The tree in the Panch Mehals was identified by Mr Dalzell, in his list of the 

 P.M. trees, April 1863, with A. Verek, Guillemin et Perrotet, Fl. Senegambiae, 

 t. 56, a tree, which forms large forests north of the Senegal river, extending to 

 the edge of the desert ; is also found in Nubia and Kordofan, and yields 

 some of the best kinds of gum-arabic. But A . Verek has (generally) a third 

 infra-stipular prickle. The prickles have a broad decurrent base, and the leaves 

 are smaller and hairy. 



10. A. lenticularis, Hamilton; Benth. 1. c. 508. 



A small tree ; perfectly glabrous, armed with twin infra-stipular prickles, 

 or unarmed ; leaves large glaucous ; common petiole 3-6 in. long ; pinnae 

 2-3 pair ; leaflets 6-8 pair, about 1 in. long, obovate or oblong, obtuse. 

 Flowers sessile, in axillary spikes, 3-5 in. long; corolla more than twice 

 the length of calyx. Legume linear, flat, membranous, indehiscent, 6-9 

 in. long, 1 in. broad. 



Siwaliks of Kamaon, Rajmahal hills. Reported from the Central Provinces, 

 but I have not seen specimens. This is probably "Khyn" of Madden, Journ. 

 As. Soc. xvii. I. 570, " an armed tree with the blossoms of the Khyr and the 

 fruit of the Siris; wood excellent. Forests about Burmdeo and Punagiri."

 Sylv. t. 50. Yern. Khair, kheir, Kher. (Shaben, Burm.) 



A moderate-sized tree, with thorny branches and rough dark-coloured 

 bark. Branchlets and petioles generally dark-brown or purple, glabrous, 

 shining; below the insertion of each leaf a pair of compressed, sharp, 

 brown, shining, infra-stipular prickles. Common petiole 3-4 in. long, 

 often armed with scattered prickles, a gland below the lowest pair of 

 pinnae, and at the insertion of the 3-4 uppermost pairs. Pinnae 10-20 

 pair ; leaflets numerous, linear, imbricate, glabrous or pubescent, less than 

 J in. long, generally turning brown in drying. Spikes lax, axillary, 

 cylindrical, pedunculate, 2-4 in. long, solitary or fascicled, flowers pale 

 yellow, sessile. Petals linear, connate at the base, 2-3 times longer
