NOTES ON PHILIPPINE PALMS, II.

with a blunt apex, 20 cm long and 20 to 22 mm in diameter, squarrose 
or with the larger bracts or spathes not immersed in wool, very broadly 
ovate and terminated by a free, triangular, not appressed, point; this is 
very fineljq neatly, and striately veined longitudinally. Flowers 13 mm 
long, hermaphrodite, solitary in the axils of the bracts from which the 
summit of the corolla emerges ; the flowers are not immersed in wool, 
but are placed between and tightly embraced by two, special, elongate, 
concave bracteoles which are acutely carinate on the back and are covered 
on the carinae and at the summit with furfuraceous, appressed paleolae 
(not woolly hairs) ; calyx eyathiform, parted to the middle into 3, broadly 
ovate, obtuse, concave lobes, very finely striate-veined; corolla about 3 
times as long as the calyx, parted to about the middle into 3 oblong 
segments. Fruit 
Palawan, near Iwahig, For. Bur. 4185 Curran, May, 1906. 
Of this very distinct species I have seen fragments of the stem and of one 
leaf and a few detached spikes with flowers in an advanced stage. It is a species 
.very well characterized by its thick, squarrose, glabrous spikelets, the bracts and 
the flowers not being immersed in wool. In this respect Korthalsia squarrosa 
closely resembles K. robusta Bl., which has the same kind of spikes and flowers. 
The spikes with squarrose spathes are quite different from the usual form in 
Korthalsia, being very similar to those of some species of Zalacca. 
To K. squarrosa apparently belongs a sterile specimen collected by Elmer D. 
Merrill, No. 5384, on Hal abac Island, although this has much broader leaflets 
than those of the specimen described above ; but this in Korthalsia is. a very 
variable characteristic, as the breadth of the leaflets seems to vary on the same 
plant with its age and with their position along the stem. 
In the above-mentioned specimen collected by Merrill, the leaf is about 70 
cm long in the pinniferous part; the petiole is 10 cm long; the rachis is irreg- 
ularly armed with small alternate claws; the leaflets are few, 6 or 7 on each 
side, rhomboid, distinctly ansate, especially the upper ones, 15 to 20 cm long, 8 
to 10 cm broad; the ocrea is truncate at the summit, open on the ventral side, 
12 cm long, and armed with very slender, needle-like, horizontal spiculae, 10 to 
15 mm long. 
Vidal 4066, collected at Sorsogon, Luzon, is also a Korthalsia, but the spe- 
cimen of this number in my herbarium is indeterminable, as it consists only 
of the intermediate portion of a leaf which resembles that of Merrill 5384, hut 
larger and with a shorter petiole; probably Vidal’s specimen belongs to a species 
differing from K. squarrosa. 
CALAM US Linn. 
Calamus Hookerianus Becc. in Ann. Bot, Gard. Calcutta 11: tab. 70. 
I have identified with this species a Calamus, For Bur. 10630 Curran, collected 
at about 200 m elevation on the Adumay Hills, Province of Albay, Luzon, 
June, 1908. ' 
The above-mentioned specimen exactly agrees with plate 70 of my monograph; 
the .-leaflets, however, of the type specimen bear bristles on three nerves on the 
upper surface, but beneath only on the mid-costa, while in Curran’s specimen 
three nerves on both surfaces are bristly. 
The native country of C. Hookerianus was not previously known, the type 
specimen in the Herbarium at Kew being of uncertain origin; now that we
