P. floribundus. | PLECTOCOMIOPSIS.' 61 
less, and 2°5—3 cm. wide, but in non-eirriferous leaves up to 50—55 cm. in length, 
though not broader; the remaining leaflets,. from the middle of the rhachis upwards, 
and also those nearer to the base, becoming gradually smaller. Male spadix appa- 
rently large, ultra-decompound (not seen entire by me); the summit of one (or of a 
partial inflorescence ?) is 40 em. long and forms a large rather dense panicle, composed 
of several (about 12 in all) gradually shortening, distichally inserted (primary ?) 
branches, distinctly arched scorpioid, as are its subdivisions ; spathes (secondary Or 
tertiary ?) elongate-infundibuliform, glabrous, very finely striately veined, almost 
horizontally truncate at the mouth and abruptly extended at one side into a trian- 
gular acuminate point; branches (secondary?) inserted inside their respective spathes 
by means of a distinct, flattened pedicellar part: the lower branches (the largest) 
25—30 cm. long, with 18—20 gradually diminishing  spikelet-bearing branchlets ; 
their spathes are infundibuhform, as are also the secondary or tertiary ones, but 
smaller, loosely sheathing, widening and glabrous in their upper part, narrowing below 
and strongly furfuraceous at the base; the lower branchlets of every branch are 
7—8 em. long, and carry distichally 8—10 spikelets on each side ; upper branchlets 
gradually shorter and with fewer spikelets; the spathes of the branchlets are 
infundibuliform, have a very wide mouth, truncate and ciliate, and produced at one 
side into a triangular point; are strongly striately veined ; have the base narrow and 
furfuraeeous ; otherwise are glabrous. . Sp/kelets conspicuously scorpioid, 8—10 mm. 
long. or shorter towards the end of the branchlets, bearing two series of very 
closely packed assurgent flowers, each series composed of 4—6 flowers; spathels 
bracteiform, membranous, concave, keeled, strongly  striately veined, acuminate 
from a broad base and completely embracing the involucre; the latter concave, 
sub-dimidiately cupular, produced on the side next to the axis into 2 very 
acuminate points. Male flowers rather broadly ovoid. acute,  obsoletely 
trigonous, 3 mm. long; the calyx membranous, split almost to the base into 
3, ovate, strongly striately veined, acute lobes; the corolla about one-half times 
longer than the calyx, parted almost to the base into 3 elliptical, boat -shaped, 
pergamentaceous segments, strongly striate externally, slightly thickened at the edges, 
and with a callous apiculum ; the stamens have the lower part of the filaments 
fleshy and thickish, about as long as the corolla, linear-oblong and united together 
in their lower third part, where they form a kind of cup; the lower and rela- 
tively broad and fleshy part of the filaments is very abruptly contracted into an 
introflexed, very slender subulate thread (shorter than the thickened part) which 
carries the anther ; the anthers stand erect before the anthesis, and are dorsilly 
attached about their middle, elongate-sagittate, narrower than the erect basal part 
of the filament, deeply disjunct at the base, rather acute at the apex, and having 
the cells opening laterally.. Rudimentary ovary very small, papilliform. —O:her 
parts unknown. 
HanrrAT.—Indo-China. In Cambodia (Gourgaud); native name * Pfdau-ch s;" 
specimen with male flowers in the Paris Herbarium. Collected also in Cochin-. 
China in a sterile condition by Dr. Thorel, but the exact locality not stated. 
Sterile specimens were also collected between Saigon and Phantiet by Lecomte 
and Finet in Dec. 1911.
