494 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (ÇC. Hartmanni 
HasrraT.— British New Guinea, where discovered on the Fly River in 1890 by 
Sir William Macgregor. 
OBSERVATIONS.—1 have seen of this only the upper portion of a leaf ( which was 
60 cm. in length ) and 3 detached partial inflorescences. It is difficult to point out 
the affinities of this species, almost all New Guinean Calam? being very imperfectly 
known. Characteristics of this species are the slightly inequidistant, elongate, 
3-costulate leaflets; the short and rigid partial inflorescences with spikelets inserted 
through a distinct and long pedicel inside their respective spathes; and the fruit 
with very light-coloured, narrowly channelled and strongly gibbous scales. 
In the spikelets with a pedicelliform part included in their respective spathes 
and in the non-cirriferous leaves this approaches the species of group II. 
PLATE 230.—Calamus Macgregorii Becc. Summit of a leaf, upper surface; 
portion of a leaf, under surface; 3 partial fruiting partial inflorescences; seeds, one 
longitudinally cut through the embryo, one from the raphal side, another from the 
opposite side.—From Herb, Beccari. 
198. Catamus HaRTMANNI Becc. sp. n. 
Description.—Non-scandent. Stem as thick as a walking cane, 2:5-3 metres high. 
Leaf-sheaths . . . . Leaves non-cirriferous, in one specimen about 60 cm. long 
including the petiole, this 15 cm. in length, obtusely trigonous, striate, glabrous, 
opaque, slightly arched, very narrowly channelled along the middle on the upper 
surface, feebly armed beneath (and in its lower part also at the very obtuse 
margins) with weak, hooked prickles; rachis almost from the base bifaced with a 
rather acute and smooth salient angle above, roundish, unarmed and striate beneath ; 
leaflets not very numerous, 14 on each side in one specimen, with a bilobed 
terminal one, inequidistant, usually approximate in couples on each side with short 
vacant spaces interposed, papyraceous, rather firm, glabrous and subconcolorous on 
both surfaces, very slightly paler beneath, narrowly oblong or oblanceolate, tapering 
lower down towards a rather acute base, very suddenly contracted at the summit 
into a snort, acuminate, bristly-spinulous tip, slightly concave-convex, finely and 
acutely 3—5-costulate with a few secondary nerves interposed; all nerves naked 
on both surfaces and rather distinct also in the lower one; transverse veinlets very 
sharp, very approximate and continuous across the blade; margins very remotely 
and inconspicuously spinulous; the largest leaflets, those near the summit, 14 cm. 
long, 3 em. broad, more concave-convex than the others: the terminal cuneately 
narrowed towards the base, formed by two connate midway up: the lower ones 
gradually smaller: the smallest, the lowest, 4 em. long, 8-10 mm. broad.-—Other 
partis unknown. ! d |
