80 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [D. imbellis, 
swollen, depressed, Fruiting perianth not entirely explanate or with a very short base. 
Fruit spherical 18 mm. in diameter, mammillate or with a very broad and short 
blunt beak at its apex; scales not very deeply channelled, arranged in 15 longi- 
tudinal series, not very shining, straw-yellow, with a narrow, scarious, finely erosely- 
toothed margin and a very faint, narrow, intramarginal line; tip obtuse. Seed 
globular, very slightly asymmetrical but not ventricose on the raphal side; embryo 
exactly basal, very near the hilum, 
Hasitat.—The Malayan Peninsula. In very rich soil in the densest jungle at 
about 100 m. elevation in the district of Perak, gathered by Sir George King’s 
Collector (No, 7975 in Herb. Caleutt.) and by Father Scortechini, who in his notes 
says that it is “more Mike ‘Sepal’ than any other." 
OsseRVATIONS.—It seems a very distinct species, but the material upon which it 
is founded is very incomplete. Scortechini’s specimen consists of two portions of the 
stem, carrying old, almost rotten fruit-spadices and leaves wanting their apices. 
The Calcutta specimen bears a spadix with mature fruit, but without spathes. 
The principal diagnostic characters of D. pseudo-sepal are the elongate leaf- 
sheaths, more or less distinctly pluricostulate longitudinally; the very long, flattened, 
subplano-convex petioles; the not very numerous and not very closely-set linear 
leaflets ; the erect, small, shortly stalked, slightly branched and few-flowered spadices, 
which are inserted near the mouth of the sheath; and the spherical fruit surmoun- 
ted by a very broad, very short, blunt mucro, and with straw-yellow scales. D. 
pseudo-sepal seems, at first sight, related to D. Sepal, but on the whole it is a quite 
different plant,

DESCRIPTION—Stem . , . Leaf-sheaths. . . Leaves: the only one seen by me is not 
_ eirriferous, probably being one from the lower part of the plant; petiole. .; rachis 
convex beneath, with an acute, salient angle and flat side faces above, wholly un- 
armed on both surfaces. Leaflets numerous, very regularly set, equidistant, 15-25 
mm. apart, thinly papyraceous, rigidulous, green on both surfaces, subshining above 
slightly paler beneath, linear-ensiform, very long, the largest 35-38 cm. in length 
and uniformly of 15-17 mm. in width through the intermediate portion, begianing 
to narrow only from their upper third to a finely subulate, capillary and bristly 
tip; distinctly 3-costulate above, where the mid-costa is bristly and the side costae 
have longer bristles than the central, often with an additional Secondary nerve on 
each side interposed, also more or less bristly ; the upper surface has thus 5 more 
or less bristly nerves; on the lower surface the mid-costa alone is finely and closely 
bristly-spinulous ; transverse  veinlets rather distinct, numerous and -approximate ; 
margins finely and appressedly spinulous. Male spadiz . . . . Female spade nodding 
when in fruit, stalked by a distinct pedicellar part 6 cm, long, slender (5 mm.
