D. collariferus. ) BECOARI. THE SPECIES OF DAEMONOROPS. 183 
has very few (10-13) leaflets, aggregated into 2-3 remote groups; the petiole is 
20-30 cm. long, somewhat flattened-biconvex, with very obtuse edges that are 
armed with very small prickles; some of these stand also on the upper surface near 
the base; underneath, the petiole is armed from ithe base upwards with digitate 
claws; the rachis has on the upper surface from the insertion of the lowest leaflets 
an acute salient smooth angle, and flat side-faces; on the under surface the 
rachis is rather powerfully and closely armed with 3-nate and 5-nate claws, which 
become gradually smaller on the slender cirrus; leaflets 10-15 mm. apart on each 
group (on each side of the rachis), papyraceous, rigidulous, green and concolorous 
on both surfaces, narrowly lanceolate, or elliptical-lanceolate, or sub-oblanceolate, 
acute at their bases and rather shortly, at times rather abruptly, acuminate to a 
brush-like tip; the mid-costa is slender but very sharp, sparingly bristly-spinulous 
on the upper, and smooth on the lower surface; the secondary nerves on both 
surfaces are all slender and smooth; transverse veinlets rather sharp, not very 
approximate; margins minutely and appressedly spinulous ; the leaflets of the lowest 
group (about 6) are larger,—10-16 em. long, 15-20 mm. broad—than those of the upper 
two; in the second group the leaflets are fewer, smaller, and less closely set; the 
third, when there is one, has only one or two diminutive leaflets. Flowers...

OssERvATIONSs.— Of this I have seen only two leaves with a portion of the 
sheathed stem. It is certainly closely related to D. Forbesii, but differs from it in 
the ornamentation and armament of the leaf-sheaths; these latter having only reversed 
membranous collars, and reversed rows of black spiculae, and wanting spiculiferous 
collars or rows of spiculae turned upwards; moreover, the leaflets of D. oligophyllus 
are slightly bristly only on the mid-costa above. See observations to D. Sabut, which 
D. oligophyllus closely resembles.

13. DAEMONOROPS COLLARIFERUS Becc. in Rec. Bot. Surv. Ind. ii, 227. 
Description.—Scandent, rather slender. Sheathed stem 15-22 mm. in diameter, the 
internodes rather short. Leaf-sheaths not gibbous above, obliquely truncate at the 
mouth, armed with small erect spines exactly on the rim and around it, especially 
at the base of the petiole, with very long (as much as 5-9 cm.) often confluent 
and transversely  seriate, needle-like, rigid,  straw-coloured spines; immediately 
below the base of the petiole are two parallel collars, both deflexed, large, very 
broadly membranous and spiculiferous, and below these again are a few complete 
cristiform rings of horizontal spiculae; collars or rings of spiculae turned upwards, in 
opposition to the deflexed ones, are not present; tbe spiculae are very slender, blackish 
and deciduous with age. Leaves elongate, about 80 cm. long in the pinniferous part,
