gregariously and in small clumps. The following species of most authors are here 

 united. The two first scarcely differ, the last seems more nearly a separate 

 species and the remarkable rachis justifies its admission as a variety. Further E. 

 arundinacea shows two distinct varieties of habit, a tall handsome large stemmed 

 one of the valleys of the Circars and hills of S. India (often cult, elsewhere) ; and an 

 almost dwarf gregarious thick branched very thorny small-stemmed one 20 ft. high 

 (probably Roxburgh's jB. spinosa) which grows gregariously in the low hills and 

 laterite downs of Orissa, Ganjam, Lower Bengal and Burma. 



B. ARUNDINACEA ; rachis of infl. very glabrous shining hard, spikelets few long 

 6-12-fld., rachilla evident hirsute, leaves smooth, sheath hairy. 



B. SPINOSA, rachis striate hard not shining, spikelets many shorter 4-6-fld., 

 rachilla obscure, leaves glabrous above hairy beneath, sheath hairy, then subglabrous. 



B. OKIENTALIS ; rachis glaucous green angled almost soft, spikelets membranous 

 5-8-fld., leaf-sheath hairy with white cilia, petiole hairy. 



B. Species of which the flowers are unknown. 



20. B. auriculata, Kurz in Journ. As. Soc. Beng. xxxix. (1870) 86 ; 

 coaspitose, stem-sheaths strigose on the back, leaves lanceolate tessellate 

 by pellucid glands, sheath smooth polished, auricle naked shining. 

 Gamble Bamb. Brit. Ind. 55, t. 49. Gigantochloa auriculata, Kurz For. 

 Fl. Brit. Burm. ii. 557. 



ASSAM, SYLHET, CHITTAGONG & BURMA, Mann, Kurz, &c. 



Evergreen. Steins 40-50 ft., 2-2 in. diam., glossy, old yellow, young scurfy, 

 branches decurved, nodes hardly thickened ; internodes 18-30 in., lower shorter, 

 walls thick. Stem-sheaths 10-12 in. by 9-10 in., base broad, convexly truncate 

 where 4 in. broad ; blade 6-9 in., triangular, acute, base slightly rounded decurrent 

 and forming a rounded auricle ; blade and sheath densely strigose except along 

 the middle; ligule sharply toothed. Leaves 8-16 by l-2- in., petioles-sin., point 

 twisted scabrid, nerves 8-12, shining ; callus of sheath smooth ; auricle thick, 

 rounded, glossy. Referred by Munro to B. vulgaris, but very distinct, and easily 

 recognizable by the two hairy patches on the stem-sheath, and the thin blade. 



21. B. villosula, Kurz For. FL Brit. Burm. ii. 553 ; stems solitary, 

 stem-sheaths glabrous truncate ciliate blade 0, leaves linear glaucescent be- 

 neath tessellate by pellucid glands, callus of sheath shining, auricle solitary 

 long-fringed. Gamble Bamb. Brit. Ind. 56. 



MARTABAN & UPPER TENASSERIM, on limestone hills, Brandis. 



Stems about 3 in. diam., nodes hardly raised, internodes 12-15 in. Leaves 5-8 

 by i~f in., tip cuspidate setaceous twisted scabrid, nerves 6-12 inconspicuous ; 

 sheath minutely villous, then glabrescent, margins whitish-ciliate ; ligule short. 



22. B. Blasters!!, Munro in Trans. Linn. Soc. xxvi. (1868) 113 ; 

 stem scandent reed-like, leaves oblong-lanceolate narrowed into a glandular 

 (wrinkled ?) often hairy petiole tessellate by oblique pellucid glands, tip 

 beaked acuminate hairy, callus of sheath narrow, auricles with long stiff 

 folded bristles. Gamble Bamb. Brit. Ind. 56. 



ASSAM; at Dibrugarh, Masters. 



Leaves 10-13 by about 1| in., base yellowish, glaucescent beneath, costa 

 yellowish shining, nerves 10-12 pairs ; sheath striate, margins ciliate, sides 

 appressed-bristly ; ligule very short. 



23. B. marg-inata, Munro in Trans. Linn. Soc. xxvi. (1868) 114; 

 stems tall scandent dark-colrd. fistular, branches detiexed, branchlets 

 bracteate geniculate, lower internodes hirsute, leaves oblong-lanceolate 

 margins towards the setaceously acuminate tip shaggy with thick silky
