HiMiiT - J a v a . The authentic specimens of this species do not bear any indication
a, to the exact locality where they were collected by Eeinwardt; those referred by
Blumo to his variety nftiUt are said to come from the Preanger on the south coast of
the island. Zollinger's specimens No. 2639 (in Herb. Boiss. and Deloss.«, accotdmg
to the collector, ought to come from the foot of Mount Lamongan in tho province of
Probolin-o in East Java, but probably they were taken from plants transported to the
garden °at Bnitenzorg, since, regarding the quoted locality, the collector adds:-"ei:
H B (Horto Bogoriensi). Eadem sp.?" Martius says that this spcoies occurs also
in Borneo and Celebes, but I hare seen no specimens from these countries, and I
think the case hardly possible. The native name in Java is " Kotang Tjetjeret'
(ZolHnger).
OaaiEviTioHS.-C. Edmrliii is closely related to 0. heUroidat, from wliich it
dificrs in its larger sije and chiefly in the fruit which is almost sphsoric, but at
the same time distinctly beaked and with fewer scales. When the spines of the
leai-racbis are elongate and deflexod, as very often is the case, the leaves recall
those of C. mminalis, but in C. Riinwardiii the spines are solitary, while they are
often ternate in C. viminab. The fignte 15 representing tho fruit of C. Reinwardtii
in Martins' plate 112 probably belongs to C. Miroiiem ; it was this figure which
induced me to believe that no difference could be found between C. lUinnardm and
C Mtiroiiem as I had not seen tho real fruit o! the first, when I published my
