Description.—Slender. Leaves more delicate than in the type, not or some- 
times subcirriferous ; leaflets narrow, minutely and. closely spinulous on the three 
costz above and only on the mid-costa beneath; rachis armed throughout or at least 
in its upper portion with very short solitary claws. Male spadiz elongate, . very 
slender, filiform, very lax, partially supradecompound ; partial inflorescences few, 
jaioko $ spikelets very slender, filiform, 2-4 cm. long, horizontal or deflexed ; spathels 
Shortly infundibuliform, coarsely veined, prolonged at one side into a subulate ciliate 
point, which spreads and subtends its flower; involucre cupular, exsert from its own 
spathel and laterally attached to the base of the one above. Male flowers pece 
tinate, or perfectly flatly bifarious and subhorizontally. inserted, 1-2 mm. apart, 3-3'5 
mm. long, cylindraceous-oblong, 1 mm. thick, apiculate at the summit; the calyx 
shortly tubular, strongly striately veined, divided down almost to the middle into 
three broad triangular acute lobes; the corola more than twice as long as the 
calyx, divided almost to the base into three oblong, navicular, apiculate segments, 
which are polished outside and striately-channelled inside; the filaments of the 
‘stamens united by their bases, subulate, inflected at the apex when in the bud; 
-anthers sagittate; rudimentary pistil columnar, shortly 3-toothed at its apex. 
Hasrrar.—Java: on the south side of the volcano Tjerimai in the province of 
Cheribon, It is called by the natives “Hooy Korrot,” a name applied also to 
C. heteroideus from which they do not consider it to be different (Bl). 
OssERVATIONS.—I have seen an authentic specimen of this variety which I 
‘cannot consider specifically distinct from C.  Aeferoideus, One leaf had the rachis 
produced at the apex into a filiform very delicate cirrus between the terminal - 
pair of leaflets, I have seen also a specimen of the type O. feteroideus bearing a 
leaf. with a rudimentary cirrus.
