D. oblongus] BECCARI, THE SPECIES OF DAKMONOROPS, 147 
Os sERVATIONS.—D. oblongus is, in Java, the representative species of JD, Hystriz 
It is very closely related to the latter but apparently specifically distinct by not 
very striking yet numerous characteristics; of these, the most conspicuous are the 
more élongate cyclindraceous fruit; the shorter spines at the mouth of the sheaths; 
the leaflets, though bristly on five nerves beneath, have the bristles not very 
close together, and do not form a continuous line as in D, Hystrix; further the 
female flowers of D. oblongus have the calyx almost flat, and therefore several 
times shorter than the corolla, while in D,  Hysíriz the calyx is shortly cupuliform, 
and the corolla four times as long as the calyx; the involuere protrudes beyond the 
involuerophorum farther than in D. Hystriz, and the areola of the neuter flower is 
more evolute, eoncave and niche-like. 
The specimens of D.  oblongus upon which Blume, Martius and Miquel have 
worked, consisted of mixed up parts of more than one species, a fact which caused 
many errors. The inspection, however, of most of the authentic specimens, and 
the study that I have made of very complete specimens of the true D. oblongus, 
gathered from plants cultivated at Buitenzorg, has enabled me to disentangle the 
intricate synonymy of this species. I have thereby discovered that D. platyacanthu 
Mart. and D hirsutus Bl. are in a great measure the same as D. oblongus. The first 
description of C. oblongus Reinw. appeared in Martius large work in the first edition 
of the page 207 of Vol. IIL; this species must, therefore, be considered as establisned 
on the peculiarly elongate fruit figured by Martius in plate 160 f. IV, 1, 2. 3, but 
the leaf-sheath attributed to it, and represented in f. V of the same plate 
160, is really that of Calamus adspersus. Martius D. platyacanthus is wholly C, 
oblongus, and the spadix reproduced by him in pl. 160 is really tbat of this 
species, but with young fruit. To D. oblongus belongs also the leaf-sheath repre- 
sented in f, III of that plate, but without the * peculiar spines at its mouth, for 
these had been mutilated in the specimen used for that plate, as I have been able 
to prove by the authentic specimen. 
Daemonorops hirsutus Bl. is apparently D. Hysirix growing in Sumatra as to 
the leaves (Rumphia ii, pl. 135, f. A. B. C.) and C. oblongus as to the fruit 
(Rumphia iii, pl 135 D. E. and pl. '? D.) 
D, hirsutus var. brevifolius is apparently made up of the fruit of D. oblongus, and 
the leaves of D. íérichrous. 
Puare 59.—Daemonorops oblongus Mart, Upper part of a leafsheath and base 
oi the petiole; an intermediate portion of a leaf (upper surface); male spadices, one 
before the anthesis, the other after it. In centre of plate, a portion of female 
spadix in flower; a fruiting panicle: two detached spikelets with very elongate 
fruits. All parts from plants cultivated at Buitenzorg in Herb. Beccari.
