144 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. K. flegellaris. 
rusty-furfuraceous, as is the petiole, clawed below. Leaflets numerous. 8—15 on each 
side of the rhachis, broadly linear or oblanceolate-cuneate or very narrowly and 
long-cuneate, irregularly truncate at apex or with a triangular acute and sharply 
dentate end, conspicuously scurfy-ferrugineous below, pluricostulate-plicate, 20—30 and 
at times even to 50 cm. long, and from 1 to 3 em. broad; the basal leaflets in 
every leaf being often considerably narrower than the upper ones. The upper leaves 
of the adult plants have shorter and more distinctly cuneate leaflets, 20—25 cm. 
long, and 3—3°5 em. broad near the upper end, which is triangular and accumin- 
ate and more or less deeply and sharply toothed, the teeth being subulate and nearly 
pungent. The uppermost leaves, those at the base of the inflorescence, are much 
reduced in length, have a short petiole, a short cirrus, and leaflets briefly cuneate, 3°5— 
4 em. broad, and only 10—-15 cm. long, and are more deeply plicate than the lower ones, but 
equally sharply toothed in their upper triangular end. Ansce of the lower leaves 
5—10 mm. long, but in the uppermost leaves they attain 2 em. in length, and 
are very slender and strongly flattened. Jnfloresence simply branched, about 60 
em. long or more. Spathes tubular, closely sheathing, unarmed, the mouths truncate, 
branches arched, spreading, 15—25 cm. long, bearing 4—8 spikes. The spikes have a 
distinctly tomentose appearance, are thickish, 6 mm. in diameter (without the flowers) 
and S—9 cm. long; spathels almost entirely immersed in the wool of the flower- 
bracteoles, and protruding only with their short apices. The flowers in the 
specimens examined are in too bad a condition for an exact analysis. Frudts—seen 
only when very young—are shortly beaked. , 
Hasitat.—Malay Peninsula, Sumatra, Billiton and Borneo. This species was 
first described by Miquel from specimens collected by Diepenhorst at Priaman in 
Sumatra; Malay name “ Rotan dahanan.” Of the authentic specimens one was sent 
to me from the Herbarium at Utrecht, by the late Prof. Rauwenhoff (No. 2584 
Herb. Bogor.). From the same source I have seen specimens in the Herbaria of 
Leyden and Calcutta. It has been found in Sumatra at Palembang ( Heyne No. 19, 
Herb. Becc. ex Herb. Buitenzorg. Specimen with radical entire leaves); in the 
Malay Peninsula in the District of Perak (Scortechini in Herb. Becc., specimen 
with very long and narrow leaflets), at Assam Kumbang plain (Wray No. 3127 
specimen with very young fruits); in Johore on Mt. Austin (Ridley No. 12591— 
this number was referred by Ridley to K. rubiginosa); in Billiton (Heyne No. 2 in 
Herb. Bece. ex Herb. Bogor.—sterile specimen with long and narrow leaflets). In 
Borneo it seems a rather common plant, in Sarawak in Mt. Mattang near Kuching 
‘Bece. P. B. No. 1912 ;—this is the type of K. rubiginosa Bece.;—the specimen 
belongs to a not full grown plant, and has very narrow and long leaflets); 
similar to P. B. No. 1912 are the specimens collected by De Vriese also in 
Borneo, which were by Miquel referred to K. angustifolia; and Heyne’s No. 2528 
from Pontianak, and_Nos. E and E bis from. Bandjermain Buitenzorg Hebarium. 
OBSERYATIONS.—À very fine plant, owing to its large leaves having 
numerous leaflets, always conspicuously discolorous of a deep green above and 
intensely rusty-furfuraceous beneath, but very variable in size and shape, from 
linear to more or less cuneate, but in every case sharply toothed in their upper 
margins. K. rubiginosa Becc. in undoubtedly the not yet full grown stage of
