238 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (ÇC, heteroideus 
own; involucre cupular, truncate, entire, slightly exceeding the involucrophorum, 
entire or undulate at the margin; areola of the neuter flower lunate, rather large, 
sharply bordered, Female flowers horizontally bifarious, small, 3 mm. long; the calyx 
with a rather flat and callous base, not distinctly veined, with 3 road acute teeth; 
the segments of the corolla as long as but narrower than the teeth of the calyx. 
Fruiting perianih shortly pedicelliform. Fruit subglobular, about 10 mm, in diam., 
suddenly contracted into a narrow and rather long beak; scales in 15 series, slightly 
channelled along the middle, light-coloured or substramineous with a paler, scarious, 
finely erosely toothed margin, with a triangular not very appressed or subsquarrose 
point, Seed globular. * 
HasrraT.— Java. The authentic specimens of this species do not bear any indication 
as to the exact locality where they were collected by Reinwardt; those referred by 
Blume to his variety rup/iis are said to come from the Preanger on the south coast of 
the island.  Zollinger's specimens No. 2639 (in Herb. Boiss. and Deless., according 
to the collector, ought to come from the foot of Mount Lamongan in the province of 
Probolingo in East Java, but probably they were taken from plants transported to the 
garden at Buitenzorg, since, regarding the quoted locality, the collector adds :—“ ex 
H. B, (Horto Bogoriensi) Eadem sp.?" Martius says that this species occurs also 
in Borneo and Celebes, but I have seen no specimens from these countries, and I 
think the case hardly possible. The native name in Java is *'Rotang Tjetjeret ” 
(Zollinger). 
OxsgRvations.—C, Reinwardiit is closely related to C. heteroideus, from which it 
differs in its larger size and chiefly in the fruit which is almost spheric, but at 
the same time distinctly beaked and with fewer scales. When the spines of the 
leaf-rachis are elongate and deflexed, as very often is the case, the leaves recall 
those of C. viminalis, but in C. Reinwardiit the spines are solitary, while they are 
often ternate in C. viminalis. The figure 15 representing the fruit of C. Reinwar dii 
in Martius’ plate 112 probably belongs to C. heteroideus ; it was this figure which 
induced me to believe that no difference could be found between C, Reinwardtii and 
€. heteroiqeus as I had not seen the real fruit of the first, when I published my 
Systematic Enumeration of the species of the genus Calamus in the Records of the 
Botanical Survey of India.
