longer than broad, slightly flattened, very boldly tubercled or superficially lobulate, 
9-7 mm. long, 4 mm. broad; when it is freed from the thin crustaceous (in 
the dry condition) black integument it bas the surface polished and of a spadi- 
ceous colour; the chalazal fovea is punctiform, inconspicuous and superficial; albumen 
homogeneous, Embryo basal. 
Hasirat.—N, E. Celebes: Prov. of Minahassa near Kajuwatu at about 50 m. elev., 
Kooriers No. 183958, vernacular name “ Pondos taisi” and **Pondos aret raindang”, 
and No, 184138 from the same locality, native name * Pondos wasal,” 
OssruvaArIONs.— Very similar to 0. mollis Blanco of the Philippines of which it is 
apparently the representative form in Celebes. It differs from C. mollis by its very 
regularly set leaflets, which bear very long bristles on 3 slender coste on the 
upper surface, but only on the mid-costa below, and have the margins spreadingly 
and distinctly ciliate, (not spinulous) The spikelets are also longer than in 
C. molis; the fruit is slightly smaller, with more numerous and smaller scales, and 
smaller seed, than in the latter.

A specimen with a female spadix collected near Zamboanga in Mindanao by 
W. J. Hutchinson, July 1906 (Forestry Bureau Manila No. 4819) does not differ from 
other specimens from Luzon and Leyte that I have seen, It is therefore, apparently, 
a constant form, although very closely related to ©. mollis. 
51. Catamus Merzranus Schlecht. 
I have seen in the Berlin Herbarium another of Hohenacher’s specimens of this 
little known species, but it is hardly more complete than the others. The sheathed 
stem is 1 em. ia diameter. The leaf sheaths are very similarly armed as in C. rwalis 
with yellowish, feeble spines, 5-15 mm, long. The leaves have no  petiole; the 
rachis, in its lowest part, is slightly concave on the upper aud convex on the lower 
surface, while the lowest leaflets are inserted along a longitudinal furrow on each 
side of it. 
59. CALAMUS PsEUDO-RIVALIS Bece. 
Of this species I have described (p. 222 of this volume) the fruiting spadix only, 
the other parts being at that time unknown. Now I consider as belonging to it some 
more complete specimens collected in the year 1904 by Mr. C. G. Rogers in 
Baratang Island, one of the South Andamans (Nos. 48, 49 in Calcutta Herbarium). : 
The specimens of No. 49 are more spinous in every part, especially on the leaf- 
sheaths and petioles, than those marked No. 48, which have these parts quite 
unarmed. I do not however think it necessary to consider these last Specimens as 
belonging to a distinct variety for, by experience, I know that the degree of spine- 
scence is a very misleading and inconstant character, if it is not accompanied by 
other peculiarities,
