Luzon, Sorsogon Province, Mount Bulusan, Elmer 16672, July, 1916, in 
flower. Vidal’s sterile specimen {4066), also from Sorsogon, is doubtless 
this species, to which is also referable another sterile specimen collected 
at Laguimanoc, Tayabas Province, Luzon, by Klemme, November, 1904. 
Local name daanan (which is also the Malay name for several species of 
Korthalsia). Possibly to Korthalsia laciniosa Mart, also belongs a sterile 
specimen collected in Polillo, Bur. Sci. 10464 McGregor.

Conspectus of the species. 
a'. Leaves noncirriferous (the rachis not prolonged into a filiform, clawed 
or aculeate appendix). 
b\ Female flowers and fruits sessile or nearly so; that is, not furnished 
with a distinct pedicel derived from the lengthened involucrophore. 
c‘. Leaflets almost equally green on both surfaces. 
<f. Leaflets narrow, linear or linear-lanceolate, 1- to 3-costulate. 
e’. Spadices shortly flagelliferous, about as long as the leaves; 
fruits small, ovoid; seeds with equable albumen. 
f. Leaf-sheaths armed with slender straight spines; primary 
spathes also spinulous; leaflets very numerous; spathels 
of the female spikelets very short, bracteiform. A very 
variable plant, of which it is difficult to establish well- 
defined varieties, as one merges into the other by inter- 
mediate forms 1. C. mollis. 
< 7 *. Sheathed stem usually 15 to 20 mm in diameter; leaf- 
sheaths more or less densely spinous; leaves 50 to 80 cm 
long C. mollis (forma typica) . 
< 7 ^ Robust; sheathed stem 2.5 to 3 cm in diameter; leaves 
up to 1.2 m long C. mollis var. major. 
g^. Slender; sheathed stem 12 to 15 mm in diameter; leaf- 
sheaths almost spineless C. mollis var. palawanensis. 
f. Leaf-sheaths and spathes unarmed; leaflets numerous; 
spathels of the female spikelets very short, bracteiform. 
2. C. meyenianus. 
f. Very slender; leaflets very few and very inequidistant; 
spathels of the female spikelets shortly infundibuliform. 
3. C. Blancoi. 
e'. Spadices (male and female) extremely long, and flagelliform, 
considerably longer than the leaves. 
f. Leaflets sparingly spinulous on three nerves above, the midrib 
alone minutely hairy-spinulous underneath ; female spadix 
with thickish spikelets drawn together around the main 
axis; fruit nearly spherical (13 to 14 by 10 mm), with a 
broad, blunt, black beak; seed pitted-ruminate. 
4. C. melanorhynchus.
