154 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. K. grandis. 
The diagnostic characters of K. squarrosa are: the. subeylindrical. not entirely 
clasping, truncate ocres (not ass-ear like); leaflets cuneately rhomboidal or rhom- 
boidal, green above, white beneath; the anse rather short (5—10 mm. long) ; 
the spikes thick and squarrose ; the spathels large, loosely imbricating; the floral 
bracteoles covered with paleaceous, not woolly, hairs; the flowers, 13 mm. long 
having the style produced beyond the throat of the corolla. 
Pirate 103.—Korthalsia squarrosa Bece.—Small portion of the sheathed stem with 
an almost entire leaf and the entire ocrea (from Mernill’s No. 5384); spikes still 
keeping some of their flowers, from Curran’s No. 4185. 
DouBrruLL, INPERFECTLY Known or UNRECOGNIZED SPECIES. 
KORTHALSIA GRANDIS Ridley, Mat. Fl. Mal. Penins. ii, 217. 
Description.—A specimen of K. grandis Ridley, presented to me by Mr. Ridley 
himself, has the sheathed stem 5 cm. in diameter, the ocrea 13 em. long, truncate, 
rigid Pergamentaceous, partially disintegrated into fibres above and on the ventral 
side, armed with few, but large, short, flattened spines; the leaves are exactly alike 
the intermediate ones of the adult plant of A. Teysmannii and the leaflets are 
also of the same size, form, and colour. . Ridley states that the spadiz has long 
and thick tomentose spikes, with the wool nearly as long as the bracts (and in 
this also it agrees with K. Teysmannü), but the fruit is not described ; we there- 
fore lack the most important and reliable character wherewith to Hifi ontinto K. 
grandis from K. laciniosa as well as from K. Teysmanni- and K. ferox. Consider 
ing, however, that several of the palms growing in Singapore are identical with 
those of east Sumatra, the home of K. Teysmannù, the conspecificity of K. grandis 
with that palm appears probable. .

KorrHaLsia MacHaponIs Ridley, Mat., Fl. Mal. Penins. ii, 216. 
Of this very inperfectly known Korthalsia Ridley writes: “Stem slender, ochrea 
cylindric, 14 inch long, thorny; petiole a foot long, very thorny, with short thorns 
crowded, white, with a scurfy meal when young; leaflets alternate, remote, 12, 
the two lowest smallest, the terminal ones connate broad, the others cuneate, 
rhomboid bidentate with a long point, 6 inches long, and 3 inches wide, no petiole ” 
(ansa ?—Beco.) " 
"Perak: Kamuning (Mackado).—A young plant sent by Mr. Machado. It is very 
different from K. scaphigera. 
This may be an early stage of K. feror var. malayana Boos. 
KonTHALsIA HISPIDA Becc. Malesia, il, 72. 
Description. —Sheathed stem 10—12 mm. in diameter.  Leaf-sheaths armed, es- 
pecially on the dorsal side, with short back spines. Ocrea 20—22 em. long, dry. 
papyraceous, in the shape of a very narrow and long horn, gradually narrowing
