G. trispermus. | BECCARI. THE SPECIES OF CALAMUS—SUPPLEMENT. 97 
acutely two-edged; the apex produced into a triangular acutely keeled point and 
armed at the base with feeble, straight, schistaceous spines, and with a few other 
smaller ascendent spines on the margins, otherwise smooth on both surfaces; upper 
primary spathes also more or less flattened, narrow lower down, and gradually passing 
into the very elongate slender plano-convex axial part; the mouth of these spathes 
is obliquely truncate, entire, glabrous, produced at one side into an acuminate 
point, is feebly armed with a few, weak, straight spines, or quite smooth; partial 
inflorescences are erect, non-callous at their insertion and have a very slender axis; 
the lower ones are 20-30 cm. long and have only 3-4 spikelets on each side; 
secondary spathes very narrow and elongate, very closely-sheathing, dorsally keeled, 
smooth, otherwise very similar to the primary ones; spikelets spreading, inserted 
above the mouth of their spathes: the lower (largest. are 4-5 cm. long, and have 
about 10 flowers on each side: the upper are somewhat shorter; spathels uni- 
laterally infundibuliform, finely striately-veined, glabrous, greenish, produced at one 
side into a short triangular, scarious, more or less split point; involucre immersed 
within its own spathel, eupular, obtusely bidentate on the side next to the axis. 
Male flowers flatly bifarious, inserted at an angle of 45°, ovoid, acute, obtusely tri- 
gonous; the calyx shortly campanulate, obscurely striately veined with a flattish 
polished base, divided down to about the middle into 3 broadly triangular lobes; 
the corolla twice as long as the calyx, deeply divided into 3 lanceolate, acuminate, 
externally striate segments. Female spadiz and fruit unknown. 
Hazsitat.—The Malayan Peninsula: State of Selangor, Hulu Semangkok, collected 
in August 1904 by Ridley. who sent me a specimen of it under No. 12116, but 
this number in the “ Materials” is given to C. lanatus, while C. distichus bears 
No. 12115. 
Osservations.—I have seen a leaf wanting its basal part, and an entire male 
spadix of this species. It belongs to the group of C. palustris and therefore has 
cirriferous leaves, and  nen-flagelliferous  leaf-sheaths. It is distinguishable by 
its leaflets which stand in pairs on each side of the rachis, the bases of each 
pair being in contact and thence divergent, smooth on the nerves and on the margins, 
and as broad as those of the intermediate forms of C. javensis, strongly concavo- 
convex and_pluricostulate. 
Suppp, Phare 54.—Calamus distichus /tidley. Upper end of a leaf; an entire 
male spadix. From Ridley’s specimen in Herb. Beccari. 
119. CALAMUS TRISPERMUS Becc. Add :—Becc. in Webbia di U. Martelli, i 349, 
The following description, which completes that already given at page 412 of 
this volume, is based on a specimen preserved in the Herbarium at Kew, collected 
by Loher No. 7071, at Montalban, Province of Rizal in Luzon. 
It is a scandent and robust species. The sheathed stem is 5-6 em. and 
the naked canes 7:5 cm. in diameter. The leaf-sheaths are rather thick and 
woody, more or less covered with tobacco-coloured very appressed and almost immersed 
scales, and are strongly gibbous above, obliquely-truncate at the mouth, which is entire, 
has a sharp margin and is more or less furnished with spines; they are also armed,
