82 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. Z: clemensiana. 
each bearing several (5—8) alternate spikes. Primary spathes longer than their 
respective spike-bearing branches (20 em. long), thinly rusty-tomentose marcescent, 
and much lacerated or split along one side and reduced to strips and filaments. 
Male spikes cylindraceous, slender, 5 to 7 em. long, 10 to 11 mm. broad, borne 
on a very short pedicel, which is embraced by a short and broad membranous 
bracteiform secondary spathe; the spathels or braets of the spikes are bracteiform, 
concave, very broad, acute and striate, individually distinet and not united together 
so as to form annular involucres (at least at the flowering time), and invisible 
from the outside even when the flowers are very young; bracteoles densely woolly 
ramentaceous. Male flowers (pink, at least, when young—Elmer) small, 5 mm. long, 
protruding above the spathels. by the full length of the corolla; calyx at first 
entire, later split into 3 hyaline, striate segments; the corolla is not much longer 
than the calyx, three-parted nearly to the middle, attenuate and solid below ; 
its segments ovate, subacute, spreading during the anthesis; stamens all of the 
same length; filaments thickish with subulate apices, curved outside during the 
anthesis; anthers oblong, obtuse. Female spadices apparently shorter than the 
male ones and having a thicker axial part; one (entire or a branch?) seen by me 
bears several very approximate .sessile spikes, almost hidden by the disintegrated 
spathes, reduced to fine capillary filaments. The spikes are only 3—4 cm. in 
length, but thickish (15 mm. across), and have relatively few approximate flowers ; 
the spathels have a very broad base and a triangular point, are membranous and 
strongly striately veined; each embraces a female flower accompanied by a neuter 
one; bracteoles of the female flower  hairy-paleaceous at apex. Female flowers 
ovoid, 8 mm. long; the calyx completely divided into 3 ovate or ovate-lanceo- 
late, blunt, concave, thinly membranous, nearly hyaline, striately veined sepals ; 
the corolla is longer by one-third than the calyx, divided to. the middle into 3 
semi-ovate-triangular, thickish, acute lobes, and ventricose in the lower undivided 
part; staminodes stiff, subulate, carrying slender, acuminate, rudimentary anthers ; 
ovary globular-ovoid, covered densely with ascendent spicule ; style very short; 
stigmas relatively small, included in the corolla during. the anthesis, fleshy and 
obtuse. Neuter flowers rather large, imperfectly formed, 6—7 mm. long, at times 
not much smaller than their female flowers; the calyx is as in the female flower 
but narrower; the corolla solid in its lower attenuate part is divided above into 
three triangular thick segments; the stamens have subulate flaments and small 
abortive anthers ; rudimentary ovary none. The fruit not seen by me, but accord- 
ing to Elmer, as reported by the natives, globose and 5°5 em. in diameter and 
from the nature of the ovary certainly clothed with scales having upturned 
spinuliform tips ; probably it resembles that of Z edulis. 
Hanrrar.—The Philippine Islands.—The species was first established on speci- 
mens of the male plant only, collected by Mary Strong Clemens in June 1907 in 
Mindanao, at Lake Lanao, Camp Keithly (No. 1907 in Herb. Manila and Bece.) 
Found again also in Mindanao, with male and female spadices by Mr. A. D. Elmer 
at Todaya (Mt. Apo) in the District of Davao (Sept. 1909—No. 11879 in Herb 
Bece.). Elmer notes that it forms large dense. tufts in the moist fertile soil of 
shallow ravines near streams at about 1000 m.; grows in thickets on the Talon 
side of the mountain range, and that it is stemless, about 7 to 13 in a cluster.
