K. teysmannit. KORTHALSIA. 137 
several secondary branches, 20—40 cm. long; spathes tubular-infundibuliform, pro- 
duced above to a triangular acute limb. usually smooth or, in the lower part of 
the panicle, slightly prickly. Spikes horizontally spreading from a robust pedicellar 
part, alternate, 3—4 on each branch, relatively large, of a conspleuous tomentose 
appearance, 11—12 cm. long, and when without the flowers. 10 mm. in diameter 
throughout immediately from the base; the spathels are low. reniform, considerably 
broader than high, not or very obsoletely apiculate, united by their margins, and 
almost invisible. outside, being hidden by the very abundant wool of the flower- 
braeteoles. Flowers . . . In the fruiting perianth the calyx only remains and 
is split down to the base into 3, broadly ovate, acute, finely-striate segments. Fruit 
obovate-turbinate, flattish above, but having a short conical beak in the centre; 
it is gradually attenuate at the base, 20—24 mm. long, 17—18 mm. broad ; scales 
in 16—17 longitudinal series, with the apices not very appressed or sub-squarrose ; 
the largest scales are 5 mm. broad, slightly convex, broadly channelled along the 
centre, of a yellow straw colour in the posticous part, produced anticously into 
a thin, triangular, membranous, reddish-brown apex, and conspicuously laciniate- 
ciliate on the margins. Seed obovoid, rounded at both ends, 14—15 mm. long, 1l 
mm. broad, the surface slightly uneven, rimulose or very obsoletely tubercled, 
grooved along the lower half on the raphal side ; intrusion of the integument very 
large; albumen deeply ruminate ; embryo placed a little below the middle on the 7 
antiraphal side. | ! 
HanrrAT.—Originally described by Miquel from specimens gathered by Teysmann 
in the interior of East Sumatra at Muara dua in the Province of Palembang; 
native name ‘ Tengkurungo." Found there again by Grashoff (No. 425 Buitenzorg 
and Beccari Herbaria) It was cultivated several years ago in the  Botanieal 
Garden at Buitenzorg, whence the late Dr. Treub forwarded to me in 1885 good \ 
fruiting specimens (those described above) under the name of K. robusta Bl. 
Recently sterile specimens, which, however, I consider confidently as referable to 
K. Teysmannii, were collected again in Sumatra in Lampong by Heyne No. 317 in 
Buitenzorg Herbarium. A  Korthalsía growing in Java on the volcano Salak, of 
e^ 
which specimens from sterile plants were sent to me from the Buitenzorg Herbarium 
(Heyne Nos. 9, 40, 42, 53) and others collected by  Koorders (No. 345808) on 
Gunong Djanti, near i risi Residency of Preanger are also, I think, referable 
to K. Teysmanni. 
~ ` If K. grandis Ridley is, as I presume, the same as K. Teysmannii the 
geographical disiribution of the latter would be extended to Singapore. (See K. 
grandis Ridley among the imperfectly known species.) 
OxnsERVATIONS.—It is perhaps the largest species of the genus; very closely 
related to K. laciniosa, from which it is barely distinguishable when in a sterile 
condition. In K. Teysmamnmi, however, the ocree are of a more rigid texture, and e 
less worn-out by age and more spinous than in K. laciniosa; but the main 
differences lie in the fruit. that. of K. Teysmanni being CARATE larger than 
that of K. laciniosa, more distinctly turbinate, clothed with larger scales, which 
also are prolonged into a membranous conspicuously ciliate triangular apex.
