erose. Fruiting pertanth obconical, the fruit on that account looking as if narrowing 
to the base, and attaining 2 cm. in length. Seed globular, 1 cm. in diameter; 
when divested of the dry adherent crustaceous, apparently once fleshy integument, 
it has a pitted surface, and an elliptical deep chalazal fovea on the raphal side; 
albumen bony not deeply ruminated. Embryo basal. 
Hasirat.—Borneo. This fine and distinct palm was first described from sterile 
specimens collected by me in the forests near Kuching in Sarawak. It has been 
later found again in flower by J. Hewitt (Kew Herb.), along the Barram River in 
the N.-W. of the Island, and in fruit by D. Hallier at Amai Ambit in Dutch 
Borneo (No. 3387 in Herb. Hort. Bot. Bogor.). 
OnsERvATIONs.— The species is characterized by its large size; by its leaf-sheaths 
being covered with minute seriate spiculae ; by its conspicuously discolored rhomboidal 
leaflets, those of both ends smaller than the intermediate ones; by its spadix sessile 
erect. having a very large spathe ; by its ovoid female flowers having the corolla 
divided past the middle into deltoid segments ; by its neuter flowers being very similar 
to and only slightly smaller than the female ones; by its globose, very faint =f api- 
culate fruit suffulted by an obeonie MEATO A fruiting perianth. 
The sterile specimens from Sarawak are very variable as to the size of the leaf- 
sheaths (from 7 to 17 mm. in diam.) at times almost unarmed, the spinules being 
apparently deciduous ; the leaflets vary from 18 to 30 cm. in length, and 6 to 14 cm, 
in diameter. In Hewitt's flowering specimen the sheaths are 2 cm. in diam., and are 
provided, in addition to the small spiculae, with some laminar spines; the largest 
leaflets are 30 cm. long and 10 to 12 em. broad. In the fruiting specimen from 
Amai-Ambit some of the sheaths are 3 cm. in diameter and covered with minute 
subseriate spines ; the largest leaflets are 40 cm. long and 17'5 cm. broad. 
Prate 3.—Ceratolobus discolor Becc. Upper portion of a stem bearing the base 
of a spathe attached laterally to the upper part of a leaf-sheath ; the end of the spathe 
represented in the preceding figure; intermediate portions of a leaf; one branch of the 
female spadix. From Hewitt's specimen in the Herbarium at Kew. 
PLATE 4.—Ceratolobus discolor Bece. Portion of the sheathed stem bearing the 
lowest branehes of the fruiting spadix (the upper and terminal part of the spadix is 
wanting). Intermediate portion of a leaf. From Hallier’s specimen in the Herbarium 
at Buitenzorg. =

DzscniPTI0N.—Of middling size, 6—8 m. long. The upper part of the sheathed 
stem, in adult fertile plants, 2—3 cm. in diameter.  Leaf-sheaths gibbous above, when 
young thinly fugaciously mealy-furfuraceous and very densely clothed up to the base 
of the petiole with very minute, rigid, erect, brown hairs, disposed in very approximate 
interrupted irregular series, later deciduous and leaving the surface of the sheaths 
scabrid by their permanent bases, arranged in slightly raised finely imbricate ridges ; 
occasionally a few larger rudimentary spines appear scattered among the hairs; the
