C. Griffithianus] BECCARI, MONOGRAPH OF THE GENUS CALAMUS. 149 
with narrower segments; stamens as long as the corolla, with filaments highly 
connate and forming a long campanulate urceolum which reaches and even surpasses 
the middle of the corolla and is crowned with 6 triangular teeth; anthers broadly 
sagittate ; stigmas thick, lamellose, recurved. Neuter flowers finely striately veined 
externally, very similar to and about as long as the male ones (6 mm. long) but 
a good deal thinner; the calyx at first tubular and shortly 3-toothed, then cleft 
almost to the base into 3 lanceolate parts; the corolla slightly longer than the 
calyx and divided down almost to the base into 3 linear-lanceolate acute segments ; 
stamens with the filaments subulate, united by their bases and shortly inflexed at 
the apex, almost as long as the petals; anthers linear, abortive, versatile ; 
rudimentary ovary narrowly elongate, 3-dentate, slightly shorter than the stamens, 
Fruiting pertanth not pedicelliform. Fruit ovate-oblong or subglobose-obovate, very 
suddenly and conspicuously beaked or rostrate, 20-22 mm. long and 14-16 mm. in 
diam. ; scales chestnut-brown, in 18-24 longitudinal series, narrowly channelled along 
the middle, dull and under a strong lens finely scabridulous with slightly paler 
finely erose margins and short obtuse point. Seed, when freed from the dry (once 
fleshy) coat, lenticular, 14-15 mm. long, 12-13 mm. wide, 7 mm. thick, somewhat 
convex, sinuately rugose and superficially pitted on the .back, with a small, round, 
shallow, chalazal fovea in the centre ef the flattish raphal face; albumen equable ; 
embryo basilar.—All parts of the male and female spadix, including the flowers 
and fruits, of a uniform brown chestnut colour when dry. 
Hasitat.-—-The Malay Peninsula near Malacca (Grifith; Ridley No. 842); near 
Perak (Scortechini); at Larut in open jungle on hilly rocky localities between 60 
and 250 metres above the sea (King’s collector No. 3040 Herb. Hort. Cale.) ; in 
Selangor (Ridley Nos. 3417 and 3478). 
OssERVATIONS,—I have derived my description from Scortechini’s incomplete 
specimens and from the No, 3040 of the Calcutta Herbarium. In some of 
Scortechini’s specimens the spines on the petiole (probably of a leaf from a young 
plant) are excessively long (7-15 cm.) and the rachis in the upper angle is not 
spinulous. O. Grifithianus differs from O. castaneus in its smaller dimensions, ascendent 
stem, less densely and  seriately armed leaf-sheaths, but chiefly in the petiole 
which is nearly cylindric upwards, and in the leaflets with 3 nerves, which are 
bristly underneath, while in C. castaneus the mid-costa only bears bristles there 
and the petiole is plano-convex in transverse section. The leaflets in C. Grifithianus 
are also distinctly disposed in large groups and probably in C. ' castaneus are 
equidistant, but of this last species I had not the opportunity of seeing an entire 
leaf. The number of longitudinal series of the scales of the fruit seems a very 
variable character in this species as is also the more or less roundish shape of 
the fruit. 
Some specimens of a Calamus from the western side of the Malayan Peninsula 
sent to me by Mr. H. N. Ridley undoubtedly belong to C. Grifithianus; conse- 
quently I suppose that the C. castaneus from Tahan woods quoted by that author 
in his memoir on the “Flora of the Eastern Coast of the Malay Peninsula”
