94 The Palms of British East India. 



carina et venis 2 setigeris subtus vena centrali setulosa, 

 cupula et calyce ovato-oblongo obsolete tridentato. 



Hab. — Malacca. 



I have two forms of this, which may hereafter be found to 

 be distinct, particularly as the characters of this section of 

 Cala^mus would seem to depend in a considerable degree on 

 the armature of the petioles. I subjoin descriptions of 

 both. 



Var. A. Descr.* — Erect, armature of the sheaths the same as that 

 of the preceding species. Petioles below the pinnse very long, those of 

 the apex of the stem alone produced into flagelli, of the pinniferous 

 part about seven feet long, armed below the middle on the convex 

 under face with rather small palmate hooked prickles. Pinnce very 

 numerous, approximate, linear, 15-17 inches long, 6-7 lines broad, 

 acuminated into long bristles, upper surface with one carina bearing 

 bristles towards the apex, and two lateral veins more bristly, under 

 surface with many smaller bristles along the mid-vein ; margins 

 bristly. 



Upper flagelliferous leaves and inflorescence exactly like that of 

 small specimens of the preceding. Spikes very flexuose, ferruginous- 

 ly pubescent, one bractea and a cup to each flower. Calyx oblong 

 with three minute teeth, sometimes ciliate. Corolla rather more 

 than twice the length of the calyx, divided below the middle into 

 three oblong segments. Stamina 6 ; filaments united to each other 

 half way up, during flowering reflexed ; anthers linear- oblong. A 

 three-lobed rudiment of a Pistillum. 



Var. B. Descr.| — Armature of the sheaths like that of C. calicar- 

 pus. Petiole 7 feet in length to the lamina, which is about 4\ feet long : 



* Specimens : a leaf and male inflorescence. 



f Specimens : an entire leaf and upper part of a male plant in flower. 



Under the name Rotang Kertong, I have two specimens of a male spadix of what 

 appears an addi^onal species of this section of Calamus. In this the spadix with 

 the spathes is oblong, 19-20 inches long, the outer spathe obscurely bi-carinate 

 with two rows of ascending flat spines about the carinae, tapering into a long straight 

 stout beak, armed along the margins with very slender spines. The flowers 

 resemble those of C. petiolaris.
