£.. ornatus.) BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 367 
‘apiculate at one side; spikelets very robust, 10-18 cm. long with 10-20 flowers on 
each side; the upper ones shorter, thick and rigid, inserted at the mouth of their 
respective spathe, horizontal or more or less recurved, and slightly arched; spathels 
very shortly and broadly infundibuliform, narrow at the base, truncate, entire, 
slightly apiculate at one side; involucrophorum inserted inside its own spathe at the 
base of the one above, cupular, posticously two-keeled; involucre exsert from the 
. involuerophorum, somewhat unilaterally cupular, rather deep, shining inside, entire; 
areola of the neuter flower large, ovate, very sharply bordered. Female flowers flatly 
bifarious, about 5 mm. long. Fruiting perianth distinctly pedicelliform, the calyx 
polished in the part included in the involucre, with 3 broad triangular lobes; the 
segments of the corolla a good deal narrower and as long as the lobes of the 
calyx. Fruit large, ellipsoid sub-obovate, very suddenly and shortly conically beaked, 
3-3°5 cm. long; scales in 15 series, deeply channelled along the middle, with a 
short rather obtuse point and an erosely toothed margin. Seed when freed from 
the once fleshy integument with a very irregular and uneven surface; albumen 
equable; embryo basal. 
Hapitat.—Of this very variable species ranging from Java, Borneo, Sumatra, 
the Malayan Peninsule, and the Philippines, the following geographical varieties may 
be distinguished. 
CALAMUS ORNATUS var. JAVANICUS (BI.) Becc. 
Description.-—Leaf-sheaths almost unarmed, Leaves of the upper part of the plant 
with distinctly 5-costate leaflets; 3 costae spinulous above. Fruit scales spadiceous. 
Hasrrar.—Java; occurring on the limestone hills more frequently than elsewhere. 
It has been found also in Bantam on the hills of Seribu, on the mount near 
Tjampia and in the forest of the lower part of mount Salak (Bl.). : 
It is one of the largest known species. Its Rotang, which is very long and 
robust, is often employed as a cable stretched across rivers for moving ferry boats. 
The seed, enveloped by an acid grateful and refreshing pulp, is eaten by the 
Javaneese, which, along with the roots bruised in water, make a potion used to 
alleviate the pains of labour (BI.). 
C. ornatus receives in Java the name of ' Huy Suttie,” *'Seutti" or “Seti” and 
in the Western provinces especially that of “Huy Kassuri.” 
Some sterile specimens collected in Java by Hasskarl and preserved in the Leyden 
Herbarium bear the name of “ Huy karuk-rok." 
OnsERvATIONS,—l have seen of this, otherwise easily recognisable species, a 
portion of a male spadix and of a radical leaf of Blume’s authentic specimen, 
My knowledge of the fruit of the Javan form is derived only from the figure of 
Martius, and the descriptions of Blume, as I have seen no specimen of it. The 
radical leaves of C. ornatus differ from those of the upper part of the stem in the 
longer subterete petiole, which is armed with long and slender spines, and in the 
rachis less powerfully furnished on the back with rare, solitary, straight, more or less 
deflexed spines terminating in a flabelliform more or less deeply partite leaflet.
