Hab. Tenasserim, Bifclioko range, at 3000 ft. elevation (Dr. Braudis). 

 Allied to P. elongata^ Bl., but easily distinguished by the doubly lar- 

 ger flowers and the larger and more densely imbricate spathules.

Apparently a slender scandent rattan palm, the sheathed stems as thick as 

 the finger, the canes as thick as a common quill ; leaves interruptedly pinnate, 

 2 to 3 ft. long, without tendril, the petioles short, often saccate at base, 

 armed with shorter and longer conical thorns on the back and along the 

 margins sparingly intermixed with somewhat recurved straight short spines, 

 the reddish rachis similarly but more sparingly armed, upwards simply 

 recurved spiny ; the sheaths armed like the petiole but very densely so with 

 unequally long straight sharp spines up to an inch long or longer towards 

 the mouth, in front sending out a long prickly recurved-thorny whip-like 

 tendril ; pinnae |^ to f ft. long, alternately and interruptedly approximate by 

 twos on each side, oblong-lanceolate, acuminate, bristly ciliate towards 

 the apex, white beneath, many-nerved ; female spadix small, only ^ ft. 

 long, on a slender peduncle (about an inch long) thorny on both margins ; 

 spathes unarmed or occasionally with a minute prickle on the midrib, 

 smooth, lanceolate-oblong, slit almost to the base ; spathules shortly tubular 

 with an acuminate limb, small and distant ; female flowers minute, about a 

 line long, distichous ; calyx shortly 3-lobed, ^ lin. long ; corolla twice as 

 long with a short tube, the lobes linear-lanceolate, acute ; male flowers and 

 fruits unknown. {Calamus Jiypoleucus, Kz. olim).

Hab. In the evergreen tropical forests of E/utiand-island, Andamans. 

 Fr. May. 



There grow two or three other species of Doemonorops in Chittagong, 

 Arracan, and the other provinces of Burma, but these I know from 

 insufficient MS. figures only or from having merely seen them growing. 



N. B. D. Hystrix, Griff, is certainly identical with B. ohlongus, Bl. j 

 the spines in the latter become quite as long as in the former.
