138 . ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. K. feroz. 
From the description given by Miquel it would have been impossible to 
recognise this species, which was based upon very incomplete specimens, consisting 
only of the terminal part of the flowering plant. Of these specimens (No. 3593 
Herb. Bog.), however, I received from the Utrecht Herbarium a fragment, which 
has rendered the identification of the plant described by Miquel, with that Sag 
at Buitenzorg, and described above by me, quite certain. 
PLare 88.—Korthalsia Teysmannii Mig.—Upper end of a fruiting piant: one of 
the leaves immediately below the inflorescence ; a segment of the intermediate part 
of a leaf from a full grown plant ; portion of the fruiting spadix. From the speci- 
mens sent to’me by Treub under the name of K. robusta, Bl. (Herb. Beccari). 
Pirate 88.—Korthalsia Teysmannii Mig.—(K. grandis, Ridley). Upper part of a 
leaf-sheath with its ocrea, and base of a leaf, and an intermediate portion of it; 
from Ridley's co-ttype specimens of K. grandis in Herb. Beccari.

Description.—One of the largest. but the first description of this species was 
derived from specimens apparently belonging to not fully grown plants (P. B. 
No. 1913), which have the stem when covered with the leaf-sheaths 10—20 cm. 
in diameter. The leaf-sheaths are finely and fugaciously rusty  furfuraceous, thin 
and more or less disintegrated into fibres on the ventral side, and rather powerfully 
armed all round with straight, broad-based, rather short (5—12 mm. long) spreading 
spines, solitary or often more or less confluent by their bases. The ocre@, in the 
above-mentioned specimens, are 4—9 cm. long, closely sheathing and also rather 
thickly armed with spines similar to those of the sheaths, coriaceous in their lower 
part, but membranous and ragged or more or less disintegrated into a fibrous net- 
work above, and along the ventral (external) side. The leaves are large and bear 
several cuneate-rhomboidal leaflets, 11—25 cm. long, 6—9 cm. broad, glaucescent 
beneath, and provided with flattened anse. In one specimen, which I consider as 
representing the adult and fertile stage of this palm taken from a plant cultivated 
at Buitenzorg (introduced from Borneo) the sheathed stem is about 4 cm. in diameter ; 
the leaf-sheaths are armed on the ventral side only with strong, flattened, broad- 
based spines, 10—15 mm. long, and usually obliquely inserted; the ocrea is about 
10 em. long, dry and perishable, especially on the external side, armed with spines 
exactly like those of the sheaths or even larger, some being 2 em. long and 10 mm, 
broad at their bases, and also obliquely inserted. The leaves are very large; the 
petiole (in one specimen) is flattish above, convex beneath, 20 cm. long, 15 mm. 
broad and has no distinct callus at its axilla; the pinniferous part is 1°50 m. 
long, bears several leaflets on each side, and ends in a long and robust clawed 
cirrus. The leaflets are rigid-papyracecus, almost equally green jon both surfaces 
or slightly paler beneath than above, cuneate-rhomboidal; generally the intermediate 
leaflets of every leaf are larger than those of both ends, have 11—13 equally strong 
main nerves, ending in as many double-toothed sharp, subulate points, of which the 
central is longer than the others; the largest (intermediate) leaflets are 30—35 cm. 
long, 12—15 em. broad; the basilar are about 30 cm. long, and 6—9 cm. broad ;
