D. asteracantkus) BEOCARI. THE SPECIES OF DAEMONOROPS. 29? 
In the peculiarities of its  leaf-sheaths D. turbinatus seems to approach D. 
mirabilis more closely than other species; but in the latter the pairs of membranous 
collars are more numerous and all are complete. From D. mirabilis var. oligocyclis it 
differs in the different arrangement of the leaflets which, in that species, are more 
distinctly grouped than in D. turbinatus. 
Prare 106,—Daemonorops turbinatus Bece. Lower portion of a leaf; portion of 
the sheathed stem ; longitudinal section of the upper part of a leaf-sheath, seen 
from the inner side; the fruiting spadix almost entire. From Hallier’s No. 3042 in 
Herb, Hort. Bot. Bogor. 
TAbis. (89) DaEMONOROPS ASTERACANTHUS Becc. sp. n. 
Descrrption.—Scandent, slender. Sheathed stem about 15 mm. in diam.  Leaf- 
sheaths slightly gibbous above, beautifully armed at almost regular intervals of about 
1 cm. with complete circular rows of broad, almost lanceolate, very thinly laminar, 
spadieeous or blackish spines, with which are intermingled numerous very slender 
spiculae ; both spines and spiculae are deflexed and united by their bases to form 
several narrow, horizontal rings all round the sheaths from which they radiate; the 
largest spines are 1-2 cm. long and 1-2 mm. broad, frequently abruptly acuminate: 
they mouth of the leaf-sheath is densely armed with similar, but much longer, 
and more gradually acuminate spines. Leaves  cirriferous, 40-50 cm. long in the 
pinniferous part; the petiole is elongate, 30-35 em. long, 4-5 mm. broad, slightly 
flattened-biconvex, with rather sharp edges, which are rather closely Stud with 
straight, often 3-nate-digitate spines; the lower spines are 10-15 mm, long, the 
upper very short; the dorsum of the petiole is either smooth or armed with 
a few straight TA E spines; the rachis becomes bifaced on the upper surface 
and has an acute salient. angle, starting from its base just where the lowest 
leaflets are inserted: on the back it is armed throughout, rather closely, and 
at regular distances, with 3-nate claws; the cirrus is equally armed with ternate, 
or, at times, quinate, claws; leaflets very distinctly approximate into 3-4 groups, which 
are separated by vacant spaces 8-12 cm, long; the groups are formed by .-4 
leaflets on each side of the rachis, very approximate by their bases and inserted 
at a very acute angle; the leaflets are quite bare on both surfaces and on the 
margins, are firmly papyraceous, somewhat plieate longitudinally, almost glossy on 
both surfaces, more or less narrowly lanceolate, not very gradually but almost 
equally diminishing towards both ends; their base is acute, the apex acuminate 
and almost pungent, not, or very slightly  bristly-spinulous; the largest leaflets are 
those of the intermediate groups, and are 12-18 cm. long, and 18-20 mm. broad; 
those of the lowest group are somewhat narrower and at times longer, and Hii 
of the uppermost group, which is reduced to only 2-3 leaflets, are the smallest; 
the mid-costa is slender, very sharp on the upper surface; secondary nerves very 
faint; transverse veinlets not very conspicuous, translucid, moderately numerous, 
Spadiz (seen only in a very young stage) apparently axillary, very slender, 
cylindraceous before flowering, borne on a rather short, slender, strongly flattened, 
unarmed, peduncular part. Spathes all entirely unarmed, tubular, the one gradually
