 axils • • TREMA. 



CELTIS. F.B.I. 136 m. 



Nettle-tree. 

 Trees and shrubs with deciduous or evergreen leaves, 

 often oblique at the base and small male or bisexual 

 flowers in axillary racemes or solitary (these latter 

 usually fertile), with the characters of the tribe iq.v.). 

 Stigmas two, hairy. Pistillode in male flower hairy. 

 Fruit globose or ovoid. 



Species about 60 in temperate and tropical regions of the 

 New and Old Worlds. Fr, Micocouher. 



Celtis tctrandra Roxh. ; F.B.L v 482, III 2, including 



C. australis L., F.B.L, III I ; Wall. Cat. 369 !. A large tree : 



branchlets sometimes drooping. Leaves and young 



parts glabrous or pubescent. Leaf-stalks % inch ; blades 



2/^ to 3 by iM to 2 inches, elliptic, shortly acuminate, 



obtuse, with three nerves at the base and usually one 



other strong pair from the midrib ; the outer nerves 



again forked outwards, all rather straight : margin 



serrate. Flowers in short axillary racemes or tufts. 



Fruit spherical, size of a small pea on a slender stalk 



% inch long. 



Nilgiris : common in Ootacamund (a fine specimen by the 

 Havelock road just below the Toda mund) and on the downs to 

 Coonoor. Fyson 1765, 3094, 3095, 1910. Bourne. Coonoor 



Gen. Dist. Eastern Himalayas, South India, Burma. 



I can see no difference between this and C. australis Z., which occurs 

 from Nepal to the north-west Himalayas, and the Salt Range and west- 

 wards to Spain. 



The venation of the leaf is very characteristic. The leaves 

 droop very markedly at night as if withered : the young foliage 

 flushes pink and yellow, at Ootacamund in October.
