in 15 longitudinal series, slightly squarrose, dull cinnamon-brown, darker towards 
the point, very slightly grooved along the centre, the point scarious, slightly 
produced, and, like the margins, finely erose-ciliate. ^ Seed ovoid-elliptical, slightly 
flattened, rounded at both ends, 8 mm. long, 6 mm. broad, 5 mm. thick, coarsely 
and deeply pitted, radiately rugose around the chalazal fovea which is round and 
Conspicuous in the centre of the raphal side; albumen superficially and coarsely 
ruminated ; embryo lateral, near the base, 
Hasitat.—Dutch N. W. Borneo: Gunong Kenepai, Residency of Sambas, (Hallier 
No. 1917 in Buitenzorg Herbarium. Specimea with fruits.) A specimen in Buiten. 
zorg Herbarium (No 16328) with a female spadix in flower, collected by Teijsmann 
in Borneo, probably in the same locality, also belongs to this variety. Another 
specimen (No. 16329 in Buitenzorg Herbarium), also collected by Teijsmann, evidentiy 
in the same locality, appears to be conspecific with No. 16328. It consists of 
the upper end of a young plant, has non-cirriferous leaves, and bears slender, 
rather elongate: and clawed leaf-sheath flagella, but no spadices. To this specimen 
is appended the native name ‘“ Rotang Marauw.” 
OBSERVATIONS.— This variety is the representative form in N. W. Dutch Borneo 
of the type found in Sarawak, but differs from the latter in the more slender stems; 
and in the leaves with narrower, more inequidistant, aud often geminate leaflets. 
SurpL, PrarE 62.—Calamus mattanensis var. Sabut Bece. Portion of the 
sheathed stem; apical portion of a leaf; spadix with fruits and detached seeds (on 
the right side of the plate) from Halliers No. 1917. Lower portion of a leaf 
and an entire female spadix in flower (on the left side), from Teijsmann’s 
No. 16328. i 
173. Caramus OxLsYanus. Teijsm. & ‘Binn. Add :—Ridley, Mat. Fl. Mal. 
Penins. ii, 208. 
Ridley gives to this plant a height of 20 feet, but to the stem a diameter of 
only half an inch, which to me seems too little. He describes the leaves as being 4-5 
feet long, adding that he has never seen any leaves of 10-11 feet in length, as 
stated by Griffith; he also states that on Griffith’s label, in the Herbarium of the ` 
British Museum the vernacular name is written “Rotan Pujare", not “Rotan 
Pajare." The quite mature fruit is 12 mm, in diameter. |
