The Palms of British East India. 31 



Var. A. — Upper angle of the petiole armed with short 

 thorns, fruit oblong. 



B. — Upper angle of the petiole unarmed, fruit roundish. 



This species appears to vary a good deal, both as regards 

 the arming of the petiole, the male spadix, which is not al- 

 ways decompound, and the fruit. 



It may be at once known by the strong, very unequal, soli- 

 tary spines of the petiole ; the long linear pinnae, which have 

 a tendency to become red in drying; by the short, much 

 compressed, scorpioid, red-brown male spikes, the flowers of 

 which are very close together, and by the expanded flabelli- 

 form shape of the fruit-bearing spadix. 



Fig. 2, t. 58 of Rumph.* gives a fair idea of its fruit, as 

 does that of the end of the female spadix, fig. 1, t. 55, of 

 the same part of the male spadix. 



It possibly may be C. ruber, Reinw. Martius Palmae. 209. 



12. (2) C. collinus (n. sp.) pinnis (apicis) lineari-lanceolatis 

 (long. 1 5-uncialibus, lat. rj-uncialibus) supra tricarinatis ca- 

 rinis setigeris subtus laevibus et glabris, pedunculo spadicis 

 decompositi spathaque infima armato, calyce bracteam longe 

 superante corollam subaequante, fructibus oblongis apice 

 mammillatis. 



Hab.— Khasya hills, near Mahadeb, alt. 18-2000 feet, 

 and Upper Assam. 



Descr.| — Petiole roundish, unarmed. Pinned alternate or nearly 

 opposite, largest fourteen-fifteen inches long, nearly one and a half 

 inch broad, linear-lanceolate, with a tendency to be spathulate, upper 

 surface distinctly tricarinate, carinas setigerous, lower surface smooth ; 

 margins bristly ciliate, especially towards apex, which appears to 

 be obtuse.
