12 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. C. rostratus. 
slightly confluent by their bases, thinly laminar, narrowly lanceolate, reddish brown, 
10—15 mm. long, often obliquely inserted, others, many more, very small and 
bristle-like, approximate by their ‘bases, brittle and deciduous, leaving after their 
fall small raised finely muricate interrupted ridges; the mouth is obliquely trun- 
cate, unarmed, bordered by a narrow membranous brittle rim, and prolonged 
into an axillary perishable ligula. Leaves rather large, pinniferous part about 80 
em. in length; the petiole 18 to 20. em. long, 6—7 mm. broad, very slightly 
flattened with round margins and beset all round with unequal, at times shortly 
seriate prickles ; rhachis subterete or very obsoletely trigonous, armed on the dorsum 
with ternate, and higher up and especially on the cirrus with. 5-nate or half- 
whorled claws; petiole and rhachis covered partially with tobacco-coloured detach- 
able scurf. Leaflets 6—7 on each side of the rhachis, alternate or subopposite, 
rigid-papyraceous, cuneately rhomboidal, radiately plicate-pluricostulate, green above, 
ashy gray or whitish beneath; the base acute, non-ansate; the upper margins irre- 
gularly lobulate undulate, erosely toothed and deciduously ciliolate; the apex 
triangular-acuminate ; the intermediate leaflets are the largest, 20—27 cm. long, 
8—9 cm. broad; the lowest pair smaller’ and narrower. Spadices sessile, erect ; 
spathe lanceolate-elliptical, 28 cm. long, 5 cm. wide (in one specimen), strongly 
flattened, natrowing equally to both ends; the apex triangular and prolonged into | 
a narrow linear beak, the margins very sharp, entire, the body rigid-papyraceous, 
cinnamon brown, covered partially outside with a detachable thin tobacco-coloured 
seurf. Male panicle much divided into short, very slender, floriferous branchlets. 
Male flowers very small, 2'5 mm. long, trigonous-ovoid, obtuse; calyx very small, 
shallow trigonous. Female panicle strict; the main axis slender, sinuous, bearing 
gradually . smaller fastigiate branches, each of which is very slightly divided into 
small floriferous branchlets bearing only 2—3 femalé flowers (each as usual accom- 
panied by a neuter); spathes with a short tubular part produced at one side into 
a long subulate point; the spathels very shortly infundibular and produced at one 
side into a triangular spreading point; involucrophorum and involucre shallowly 
eupular,:3-toothed. Female flowers 5 mm. long, a little over 3 mm. in diameter, 
ovoid, trigonous-pyramidate in tneir upper part; the calyx very short, shallowly 
eupular, 3-toothed ; the corolla considerably longer than the calyx, parted to a little 
above the base into 3 deltoid, aeute segments, its undivided part being very short; 
filaments connate below with the base of the corolla, triangular in their free 
part and bearing small sagittate rudimentary anthers; ovary globose, covered with 
large suborbicular fimbriate scales; stigmas sessile elongate, thick, spreading and 
recurved. Neuter flowers very similar to female ones, only a little more slender, 
more acuminate and a trifle longer, having. like those, the lower part of the 
corolla urceolate, but wanting the ovary, and having the cavity lined with the 
bases of the filaments of the stamens; the free part of the filaments elongate and . 
filiform ; the sterile anthers are slender and sagitiate. The perianth is apparently 
explanate under the fruit; this was seen by me only when very young. 
HaBrrAT.—Dutch South Borneo. I have flowering specimens from Bandjermasin 
(No. 17 in Herb. Hort. Bot. Bogor. and Beccari) and others sterile from the same 
place collected by Heyne (19 bis and 30 in Herb. Hort. Bot. Bogor.) Sterile 
specimens, which exactly correspond to K. rigida Bl. were also collected by Hallir
