300 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. spathulatus. 
phorum subdiscoid, shortly pedicellate ; involucre flat, discoid, entire, irregularly orbicular ; 
areola of the neuter flower tuberculiform. Fruiting perianth pedicelliform; the calyx 
cylindraceous, smooth and callous at the base, divided down to the middle into 3 broad 
semiovate rather obtuse lobes; the segments of the corolla slightly longer than the 
calyx, lanceolate, acute, striately veined outside; the filaments of the stamens forming 
an urceolate cup, which is crowned by 6 elongate triangular teeth. Fruit broadly 
ovate-elliptic, about 12 mm. long and 8 mm, broad, suddenly contracted at the 
apex into a small acute beak; scales in 18 series, reddish-brown with a darker 
( almost blood-red ) shining marginal line, rather convex, faintly channelled along the 
middle; margins erosely toothed, Seed with equable albumen. 
Hazirat.—British New Guinea on Mt. Obree at about 2,500 m. elevation, 
Discovered by Mr, W. A. Sayer in the summer of 1887. The specimens were sent 
to me by the Baron Ferd, von Mueller. 
Opservations.—The description of this species is derived from a specimen consist- 
ing of only two leaves and one spadix with immature fruit. The spadix is 20 cm. 
long with two partial inflorescences, and the terminal portion is wanting. ‘The two 
leaves are without the basal portion of the petiole; one is 20 cm. and the other 
23 cm. in length, ‘The affinities of this species are somewhat uncertain. In the 
short not cirriferous leaves with few leaflets ( of which 4 approximate at the summit ) 
it approaches the species of the group of C. javanicus, but in spadix it has a general 
resemblance to the species of Group XII ( C. heteracanthus, adspersus, etc.) mainly on 
account of the secund arrangement of the flowers and of the subpedicellate involucro- 
phorum. The characteristic marks are: the short not cirriferous leaves with very few 
equidistant unicostate lanceolate leaflets of which 4 are approximate at the summit, the 
rigid short spadix, the spikelets with secund flowers, the discoid shortly pedicellate 
involucrophorum. | 
PrarE 148.—Calamus Cuthbertsonii Becc. The entire specimen described above. 
128, Cazamus sPATHULATUS Becc. in Hook. f. Fl. Brit. Ind. vi, 459 and in Rec. 
Bot. Surv. Ind. ii, 215. 
Descrretioy.—Slender, apparently scandent, at first sight glabrous, but in fact 
covered throughout, except on the leaflets, flowers and fruit with very small rusty 
scales which are scattered on the sheaths, rachis and primary spathes, and denser on the 
secondary spathes and spathels. Sheathed stem 10-12 mm. in diam. Lenf-sheaths flagelli- 
ferous, pale-yellowish (as are the other parts of the plant when dry) very thickly 
coriaceous, gibbous aboye, densely armed with short, 3-8 mm. long, solitary, scattered 
or sometimes slightly eonfluent spines, which are swollen or bulbous and light-coloured 
at the base and with an ascendent narrowly triangular, underneath flat, black tip. 
Leaf-sheath flagella very long, flattened and acutely two-edged in the basal part, 
densely aculeolate upwards, Leaves short, in ‘one specimen (Lobb’s) 50 cm. long, 
including a slender filiform aculeate terminal cirrus; another specimen (Hervey’s) has 
& leaf subcirriferous and bears at the summit at different levels 2 unequal leaflets the 
uppermost of which is laterally aculeate on the rachis side; petiole very short, flat
