166 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [D. verticiifaris 
its juice is said to be similar to that of the ''Mamina tree” (Carumbium 
amboinicum Miq.) The Rotang is useless. 
D. Calapparius has been rediscovered in Amboina by Hombron (Herb. Mus. 
Paris) and more recently by De Vriese (Herb. Leyd.). 
OssrRvATIONs.— Hombron collected this species during the voyage of the 
** Astrolabe” and ''Zelée," between the years 1838-40. Hombron’s specimen consists 
of only an apical portion of a very young leaf and of one fruit. The latter is 
somewhat larger than that described above, but otherwise identical; it is as much as 
28 mm. in diameter and its seed is 20 mm. thick with the chalazal fovea apical, the 
surface unequal, and furrowed along the raphal side. 
,D. Calapparius is easily distinguishable by its comparatively very large fruit, and 
conspicuous, pit-like, deep chalazal fovea, situated near the top of the seed, and 
opposite to the embryo which is basal. Generally in the seeds of Daemonorops the 
chalazal fovea is placed in the central part of the raphal side, or is obsolete, 
~ I discovered, in the ancient collections of the Museum of Florence, a small branch 
of the original Palmijuncus  Calapparius of Rumph with mature fruits, apparently 
the same branch which is figured in the “Herbarium Amboinense," and which was 
sent by Rumph himself in the year 1682 to the Grand Duke of Tuscany (see 
* Martelli : Le Collezioni di G. E. Rumph, p. 163). I have received from the 
Leyden Herbarium a portion of the type specimen of Calamus amboinensis Miq. which 
has enabled me to positively identify it with Rumph’s Paimüuneus Calapparius. 
I have derived my description from those of Rumph and Miquel, and as to the 
leaflets and fruit from Miquel’s type specimen of C. amboinensis in the Leyden 
Herbarium, that of Rumph not being now available. Calamus (Daemonorops) 
amboinensis var. spinosior Miq. perhaps represents a different species from 
D. Calapparius, and probably some of the characteristics attributed to C. amboinensis 
as given in Miquel’s description do not belong to it, but to the variety 
spmosior, Miquel in his description speaks of 2 spadices, one large, the other small ; 
in the first the axial parts are glabrous, and in the second, which I have seen, 
these parts are furfuraceous and finely scabrid, and the fruit is perfectly spherical 
exactly as in Rumph’s type specimen of Palmijuncus Calapparius.
