NOTES ON PHILIPPINE PALMS, II. 
625 
A very peculiar species belonging to the group of G. palustris, but with a 
seed having a ruminate albumen and with the leaflets equidistant, lanceolate, and 
5-costulate. It is related to G. Arugda. Of this species I have seen only a leaf, 
the summit of a spadix, and a few fruits. 
Calamus mindorensis Becc. in Philip. Journ. Sci. 2 (1907) Bot. 235. 
This species was originally described from the female plant only. Male 
specimens have now been collected, also in Mindoro, by M. L. Merritt, in June, 
1907, For. Bur. 6211. It is a commercial rattan. Native name tumalin. 
It is a very high-scandent plant. The specimen seen by me has a 
sheathed stem 5 cm in diameter. The leaves are abont 2 m long and 
terminate in a very robust cirrus; the petiole is almost obsolete; the 
leaflets are as already described ( l . c.) Male spadix forming a large, 
compound and diffuse panicle, 2 m in length, glabrous in all parts, divided 
into several triple-branched, partial inflorescences ; primary spathes thinly 
coriaceous, greenish-yellow, tubular, tightly sheathing, smooth; the first 
spathe is 15 cm long, and about 3 cm broad, flattened, two-edged, the 
edges very sharp and spinous above, horizontally truncate and fringed 
with paleaceous scales at the mouth, prolonged at one side into an 
elongate, triangular, dorsally-keeled and spinous point. The partial in- 
florescences are flexuous, very long and slender, one, belonging to the 
lower part of the panicle, is 1.2 m in length, with its axial part 5 to 6 
mm thick at the base and with about 12 branches, distieally inserted on 
each side; secondary spathes tubular, tightly sheathing, 3 to 4 cm long, 
smooth, entire, truncate and also ciliate at the mouth, and prolonged at 
one side into a triangular acute point; the secondary branches are in- 
serted outside the mouth of their respective spathes, and have a distinct 
axillary callus, they are slender, flexuous, 2 to 2.5 mm thick, 30 cm long, 
or thereabouts, and bear numerous distichously arranged spikelets; the 
tertiary spathes are smooth, elongate-infundibuliform, 10 to 15 mm long, 
truncate and ciliate at the mouth like the others, prolonged at one side 
into a triangular point which subtends their respective spikelets. The 
spikelets are spreading, arched, usually 2 cm long, or at times shorter, 
comb-like, bearing about 20, very approximate, exactly bifarious flowers 
on each side, and when measured wjtli the flowers are about 6 mm broad ; 
spathels very short, very closely packed, concave and almost boat-shaped, 
obtuse, and deflexed; involucre formed by two concave bracteoles united 
by their bases, and immersed in their respective spathels which contribute 
with the involucre to form a small cup to their respective flowers. 
Flowers in contact one with the other, the full grown buds 2.5 to 3 mm 
long, cylindraceous, apiculate; the calyx has 3, deltoid, acute, deeply 
striate teeth ; the corolla is twice as long as the calyx. 
Calamus trispermus Becc. in Perkins Fragm. FI. Philip. (1904) 46, et in 
Ann. Bot. Gard. Calcutta 1 1 : tab. 180. 
Of this species, which was described from very incomplete material, I have seen 
recently in the Kew Herbarium, a fine specimen with an entire fruiting spadix,
