NOTES ON PHILIPPINE PALMS, II. 635 



12 flowers on each side; the upper are shorter and bear fewer flowers. 

 The spikelets in Loher's specimen are therefore somewhat more slender, 

 and bear a few more flowers than those of Vidal's No. 988, but are 

 otherwise identical with them. 



Calamus Blanco i Kunth Enuni. PI. 3 (1841) 595; Becc. in Webbia 1 (1905) 

 66, Ann. Bot. Gard. Calcutta. 11: t. G' f . 



A specimen with a female spadix collected near Zamboanga, Mindanao by 

 W. I. Hutchinson (For. Bur. J t 819), July, 1906, does not differ from other specimens 

 that I have seen from Luzon and from Leyte; it is therefore apparently a constant 

 form, although closely allied to Calamus mollis Blanco. 



Calamus discolor (Mart.) var. negrosensis Becc. var. nov. 



A specimen of a Calamus collected by F. Damw in Negros, apparently belongs 

 to a distinct variety of the form which I have recently described in Elmer's 

 "Leaflets" as typical C. discolor. The specimen consists only of the upper part 

 of the leaf, and of a few partial inflorescences of a male spadix. There is not 

 however all the requisite evidence to prove that this specimen really represents 

 the male plant of C. discolor, although the male spadix of the type, and the 

 female one of this proposed variety are unknown; the leaf, however, of the plant 

 from Negros, with its leaflets white beneath, though endowed with some peculiar- 

 ities of its own, leaves little doubt as to its specilic indentity with or at least of 

 its great affinity to C. discolor. 



It is a high-climber. Leaf-rachis rusty-f urf uraceous ; leaflets very 

 numerous, equidistant, very narrowly linear-lanceolate, broadest at about 

 their middle, green above and white beneath, exactly as in the type, 

 from which, however, they differ in being smaller, and in having a few 

 bristles on the mid-costa above only, while the under surface is sprinkled 

 all over, except at the base, with scattered, small, spadiceous, subspiny 

 bristles; the largest leaflets, i. e., the mediate, are 20 to 22 cm long, 

 and 9 to 10 mm broad. Male spadix apparently rather large, with 

 several partial inflorescences; each of these forming rather dense panicles, 

 20 to 30 cm long, twice branched, covered with a soft detachable whitish 

 scurf on the spathes and spathels ; secondary spathes infundibuliform, 

 rather loosely sheathing; branches 10 to 12 cm long, or at times less, 

 bearing a few gradually decreasing branchlets, which carry 4 to 6 dis- 

 tichonsly arranged spikelets on each side; the spikelets are inserted at 

 the mouth of their respective spathes, are 2 to 3 cm long, flattened, 

 comb-like, with perfectly bifarious, horizontal, contiguous flowers; the 

 axes of the spikelets are slender, not brittle; spathes very short, concave, 

 apiculate at one side, very strongly and firmly striately veined; involucre 

 cupular, obliquely truncate, 2-dentate on the axial side. Flowers small, 

 ovoid; the calyx sharply and firmly striately-veined like the spathes, with 

 3 acute teeth.
