l. siphonospathus ) BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 471 
A cultivated male specimen forwarded to me from Buitenzorg is more robust than 
the wild ones seen by me in herbaria; it has a sheathed stem 14 mm, in diam.; 
the sheaths are armed with more robust spines; the petiole is very short, almost 
smooth; the pinniferous part is 80 cm. long with about 10 leaflets on each side, o 
which some are as much as 30 cm. long and 3 em. broad; the cirrus is 50-60 cm. long. - 
According to Blume some of the leaves (seemingly those of the lower part of the 
plant) are not cirriferous and terminate in two confluent leaflets. 
C. melanoloma is a very well-marked species which keeps a green colour in 
herbaria. It is chiefly distinguishable by its very similar male and female spadices; 
the slender stem; the sheaths armed with scattered spines, otherwise smooth and like 
the spathes and spathels not scabrid; the rather small leaves with not numerous lanceo- 
late or oblanceolate 3-5-costulate inequidistant not fascicled leaflets; the costae naked 
on both surfaces; the fruit elongate-ellipsoid, beaked; the scales with an almost black 
margin and tip.

Description.—Scandent, slender or of moderate size, more or less covered in the 
younger parts with a rubiginous removable scurf. Sheathed stem 1-4 cm. in diam. 
Leaf-sheaths gibbous above, armed with very thinly laminar confluent and seriate or 
even scattered, opaque, schistaceous-brown or light coloured, 1-3 cm. long spines. 
Ocrea extraordinarily large, rigid and thickly papyraceous, even 20 cm. long and half 
sheathing the younger part of the terminal shoot, densely armed like the sheaths, 
Leaves rather large and elongate, 1-1:5 m. long in the pinniferous part and terminated 
with a leng and rather robust cirrus; petiole more or less elongate, usually prickly 
_all round, but chiefly in the upper surface and at the margins, biconvex, except 
at the base, where flattish above; rachis more or less prickly in the upper surface, 
where  bifaced (obsoletely at first and acutely towards the summit); in the lower 
surface armed at first along the middle with small, remote solitary black-tipped 
claws, which higher up are ternate and then digitate and very sharp, in number 5-7 on 
the cirrus; the half or three-fourth whorls formed by these large claws often alternating 
with smaller whorls of more delicate ones ; leaflets very numerous, subequidistant , 
very closely set, 15-20 mm, apart or sometimes with longer spaces interposed, papy 
raceous, rather firm, green and subconcolorous on both surfaces, linear or linear- 
lanceolate slightly attenuate towards and suddenly  plicate at the base, very 
gradually acuninate into a long subulate filiferous tip; almost all of the same size
