there with a small apicuUim which penetrates into tho pedicelliform perianth. The
dry fruits vary from 3-3-5 ctu. in length and 20-23 mm. in breadth ; those
oroserved in alcohol measure evon i cm. (including tho beak and the basal apiculam)

dark spadiccous, with darker not very distinct iiitramarginal line; when dry almost
black, channelled along the middle, rather obtuse or slightly prolonged into a point;
margins erosely toothed. Seed, when fresh, enveloped by an abundant pulp, 22 by
14 mm., when dry and freed from the integument 15-18 mm. long aud 12-13
mm. broad, very irregular, suborbicular or obloug in outliue, with a very uneven
sarfaco; ilattish on the back, rather convex aud boldly tubercled on tho raphal side
with a narrow and deep chaiazal fovea there; albumen equ.ible ; embryo basal.

DEBCRIPTION.—Fruit ellipsoid, 3-5 cm. long 23 mm. broad, very suddenly and
shortly conically beaked ; scales in 15 series, deeply channelled along the middle,
reddish brown with a narrow black margiuant line. Seed oblong very obsoletely
and irreguiiirly 4-angular, 18 mm. long, 15 mm. broad, 13 mm. thick, when freed
from the crustaceous, once fleshy integument.
HABITAT.—Tiie Philippines in Central Luzon, Loher No, 1387 in Herb. Kew.
OBSEKVAI-IOSS.—I have seen of this only a portion of a fecnale inflorescence with
mature fruit, but I was struck by the form of its seed, which corresponds with
Blanco's deseriptio:i " una semilla oblonga con i ángulos confusos," a form which I
have not met with in any other Caiamvs. The fruit is said to be eaten by the
natives, and this is a proof of its large size. The other characteristics oí C.
maximus in Blanco's description correspond also fairly well with thoso of 0.
arnatus. The identification of 0. maximus with C. ormius Bl, docs not, however,
alter the nomenclature of this species as the name ormtus is more ancient than that
given to tho same plant by Blanco.
CALAMUS OESATUS var. MITIS Becc. in Kcc. Bot. Surv. Ind. ii, 21I).
DEsnaiPTioN.—¿ea/'s/ícaí/is strongly gibbous above, armed on the ventral side
mainly near the mouth with a few large broad laminar spines, naked elsewhere.
Leaves subcirriferous; rachis armed with robust solitary geminate or ternate claws;
leaflets gradually decreasing in size towards the summit, those of the cirriform
portion of the rachis 3-4 cm. long with a brush of black bristles at the apex;
the largest leaflets distinctly 5-co8tate, usually with the mid-co«ta only spinulous

and the side nerves naked or with very few spinules. Male spadix as in the
typo. Fruits unknown.
HANITAT.-Borneo ; in Sarawak at Penindgiao {Beccari P. B. No. 085—Nov. 1895)
and at the foot of Mt. Mattang {Beccati P. 13. No. 1937). In Sarawak it receives
the name of " Rotang Samambu." This Calamus was also gathered in Borneo by
Low, who assigns to it the Malay name of " H. Selyan," but his specimen is not
accompanied by any special indication of locality.
OBSERVATIONS.—The specimen No. 983 of the Bornean plants consists of portions
of a male spadix in flower and in portions of radical leaves, whicli do not differ
in any way from the corresponding parts of the Javnn form.
The specimen No. 1937 consists of a leaf of an adult plant with its leaf-sheath
7 cm. in diameter.
Low's specimen in the Kew Herb, is a less robust plant than those quoted above.
The leaf-sheath is fiagcllifevous and ouito unarmed. Tlie summit of a leaf is
terminated by two leaflets connate by their bases, one decurvcnt or inserted higher
up than the other.
PLATE 154.—CALAMUS OENATUS var. MITIS Becc. Leaf-shenth with the base of a leaf
and of a flagellum leaflet (upper surface) with portion of the rachis ; subcirriferous
summit of a leaf from the upper part of aa adult plant from Becc. P. B. No.
1937. Partial inflorescence of a male spadix, from Becc. P. B. No. 985.
