Cclastrus. pentandria monogynia. 



A ramou?, remarkably rigid and thorny shrub, rising as far *s 

 eight feet in height. Branches thick, round, without any tendency to 

 become angular, strongly flexuose, ash-coloured, dotted, smooth, as 

 are all the other paits. Spines alternate, issuing frdra the flexi 

 of the branches, often exceeding two inches in length, strong aiid ri- 

 gid, round, divaricate, producing leaves and even flowers, end gra- 

 dual y growing out into branches— Leaves at first fascicled on the 

 spines, their insertions surrounded hy a number of snbu ate, mnr.ite, 

 evanescent, ciliate bud-scales, becoming alternate ; oboyate-cttneate, 

 acute or obtuse, more frequently retuse, on o!d blanches neaiiy 

 round-obovate, sharply serru ate, tapering and entire at the bas« 9 

 from one to two and a half inches long, firm and leathery, smooth, 

 glossy above, of a pale-yellowish green underneath, with sub-oppo- 

 site, filiform nerves, and reticulate capillary veins. — Petiol \trj 

 short, slightly sulcate. — Flowers small, sub-corymbose on capillary, 

 fascicled peduncles, inserted on the spines among the leaves. Pedi- 

 cels sub-dichotomous. Bractlets opposite. Lacinia of the caiv-< 

 ciliate. Style bifid. 



Obs. Linneus's C. buxifoiia is a native of Africa, its branches ar? 

 angular and straight, the leaves crenate, not sharply serrate, and the 

 flowers panicled : differences which, in my estimation suificientfy 

 w arrant my separating the Travancore species under a distinct name, 

 -N.W. 



13. C rufa, Wall. 



Arboreous, erect, smooth, sparingly armed with axillary short 

 spines. Leaves lanceolate, acuminate, serrulate. Corymbs axillary, 

 capillary, fascicled, on capillary coloured peduncles. Capsule obo- 

 "vaie, triangular, three-seeded. 



Common in the forests of the valley of Nipal. I have also found it 

 at Tambakan. Blossoming in March and Apiil ; fruit ripening in 

 June. 



A large very branchy tree. Branches round, brown, dotted, sca- 

 brous, sparingly armed with axillary, short, straight spines general'y
