C. macrochlamys-) BECCARL MONOGRAPH OF THE GENUS CALAMUS. 959 
chartaceous and not reduced to filaments, and in the larger leaflets. It is also allied 
to C. macrochlamys, but this has lanceolate and distinctly grouped leaflets. 
It is a somewhat variable plant. Number 242 of Lauterbach has the upper and 
very young part of the sheathed stem 14 cm. in diam, furfuraceous and armed 
with a few small spines; its flagella have the first spathe almost unarmed; the ocrea 
is 13 cm. long and is furnished with some very slender spiculae, which perhaps dis- 
appear with age. Another specimen of a leaf from a sterile and probably young plant, 
collected by Dahl at Ralum (Herb. Berol.) which I consider also as belonging to 
Q. ralumensis, has a portion of a sheath armed more than usual with short scattered 
horizontal spines and the leaves with a petiole which is 45 em. long, roundish, 
slightly channelled above, and rather strongly armed with short spines, and the leaflets 
subequidistant ; another specimen of the same gathering has also some short spines on 
the sheaths, and the leaf with a petiole 15 cm, long, flattish above and round beneath, 
where armed only along the middle with light-coloured claws ; the leaflets are more 
or less distinctly grouped, with vacant spaces 6-7 cm, in length, but otherwise not 
differing from those described above. C. Jongipinna seems to me nothing more than 
the male plant of C. ralumensis. 
Puare 89.—Calamus ralumensis Ward. An entire partial male inflorescence with 
very young flowers from the lower portion of the spadix; the summit of a leaf 
from underneath; an intermediate portion of the same leaf from above.—From the 
type-specimen of €. longipinna, Laut. and K. Sch. in Herb. Berol. 
Prate 90.—Calamus ralumensis Warb, Terminal portion of a plant with an entire 
ocrea and the base of a leaf, intermediate portion of a female spadix in flower, 
from Lauterbach No. 212, Ralum in New Pommerania in Herb. Berol.; intermediate 
portion of a leaf from underneath and terminal portion of a female spadix with 
young flowers, from a specimen of Warburg in Herb. Berol.

C. Hollrungii (not of Becc.) K. Schum. & Laut. Fl. Deutschen Schutzg. in 
der Südsee, p. 209. 
Descriprion.—Apparently scandent and of moderate size. Sheathed stem about- 
2 cm. in diam. Leaf-sheaths (in the small portion seen by me) unarmed, strongly 
gibbous above. Ocrea extraordinarily large, auriculiform, recalling the ears of the ass, 
up to 35 cem. long, enfulding the younger part of the stem, covered with fuscous- 
furfuraceous scurf, chartaceous, exsuccous, rigid, later split longitudinally on the outer 
side, not dissolving into fibres, furnished mainly near its margins with very small 
confluent spinules (which are disposed in oblique lines) or with small raised approxi- 
mate very finely spinuliferous crests. Leaf-sheath flagella almost unarmed and somewhat 
flattened in their lower portion. Leaves rather short (about 90 cm. long), not cirri- 
ferous; petiole rather short (11-12 cm. long) almost biconvex, unarmed and with 
rather obtuse margins; rachis smooth and acutely bifaced above from its base, very 
densely armed beneath with numerous solitary not large dark-tipped claws; leaflets 
not numerous, very conspicuously approximate into 4 opposite bundles of from two to 
four pairs each, with vacant spaces 12-20 cm. in length between each bundle; the
