make use of the specific name of fascicularis, which had been already taken by 
e. fascicularis Roxb., proposed the name of C. Fernandezi in memory of Griffith’s 
intelligent collector in the Malayan Peninsula. 
IV.—Teysmann and Binnendijk, in the Catalogue of the Buitenzorg Garden 
for 1866, mention C. Ozleyanus as a native of Malacca and Bangka, which was 
afterwards described and figured under that name by Miquel (l. c.) in 1868. In 
this I at once recognised the Rotang Pajare, chiefly on account of the peculiar 
arrangement of the leaflets. 
V.—C. Oxleyanus has nothing to do with a Daemonorops, being a well 
characterised species of Calamus; consequently its oldest name of fasciculatus cannot 
be retained; no more can that of C. Fernandezi, this last being more recent 
than the name C. Oxzleyanus. 
C. Oxleyanus is a highly characteristic species, being erect and at the same time 
being furnished with a powerful climbing apparatus, viz., the strongly clawed cirri; 
perhaps only with age the plant acquires a climbing habit. It is also distinguish- 
able by the long petioles, and especially by the aggregation of its leaflets in remote 
groups of even 10-12, on each side, where the leaflets are equidistant and in one 
plane and not pointing different ways. 
I have derived my description chiefly from the cultivated specimens which I 
have received from Buitenzorg: these have decayed male spadices and female ones 
with young fruit. Ridley's specimen has a portion of a female spadix with growing 
ovaries. I have not seen the mature seed.

DzscRiIPTION,—Seandent, slender. Sheathed stem about 15 mm. in diam. Leaf- 
sheaths gibbous above, cylindraceous, obliquely truncate at the mouth, quite unarmed 
green, sprinkled with very small punctiform brown scales. Ocrea very short, liguli- 
form and narrowly bordering the mouth of the sheath, Leaves about 80 em. long in 
the pinniferous part, the cirrus slender, with approximate half-whorls of small black- 
tipped claws; petiole 8-20 cm, long, flat above and round beneath with acute 
margins, smooth or very sparingly spinous; rachis smooth above, irregularly armed 
beneath along the middle and at the sides with small black-tipped claws; these soli- 
tary near the base and ternate higher up; leaflets numerous, grouped in many small 
alternate or sub-opposite fascicles of 2-4 on each side of the rachis, the fascicles 
separated by vacant spaces 5-10 cm. long; in each fascicle the leaflets are very approix- 
mate by their bases and divergent, narrowly lanceolate, a good deal narrowed to 
the acute base, gradually acuminate at the summit into a finely subulate tip, thinly 
papyraceous, green and concolorous on both surfaces, 20-30 cm. long, 15-20 mm.
