C. ornatus. | BECCARL MONOGRAPH OF THE GENUS CALAMUS. 365 
where rounded and very suddenly contracted into a short triangular bristly-penicillate 
tip, firmly papyraceous or subpergamentaceous, very glabrous, hairless or spineless 
and shining on both surfaces, with the mid-costa slender and acute above and 6-8 
very slender but sharp secondary nerves on each side of it and a strong primary 
nerve considerably thickening both margins; the margins themselves quite smooth; 
transverse veinlets very sharp and distinct on both surfaces, excessively numerous, very 
approximate and continuous across the blade; the largest leaflets are the: intermediate 
ones, and these vary from 8-12 cm. in length and 3-4 cm. in width in small 
specimens, and from 20-27 by 5-8 cm. in the larger oues; those near the base 
are considerably and the two of the terminal pair only slightly smaller.—Spadices 
unknown. : 
HasrrAr.— The Malayan Peninsula near Malacca, where it was first discovered 
by Griffith’s collector E. Fernandes (Herb. Kew.), and recently found rgain near 
Perak by the Revd. Father Scortechini; always sterile (Herb. Beccari). 
OssERVATIONS.—Griffith’s specimen in the Herbarium at Kew consists of two entire 
leaves with their leaf-sheaths, these 8-9 mm. in diam., and with only 7 leaflets (8-12 
em. long) including the two, highly connate, of the terminal pair; the sheaths 
armed with small tubercular prickles. Scortechini’s specimens are a good deal larger, 
and the leaf-sheaths are more strongly armed, and one of these bears the base of a 
flagellum. It seems, however, that both specimens are from young and not yet fertile 
plants; as they stand they differ from the specimens of the adult C. spathulatus im 
the leaf-sheaths being armed with horizontal or slightly deflexed spines (not ascendent), 
in the leaves with longer subterete petioles, and in the unicostate less elongate leaflets. 
The doubt remains whether these differences depend on the age of the plant.
