336 Flora of the Malayan Peninsula. 
Differs from Korthals’ specimen only by the presence of peripheric lysigen- 
ous canals. 
65. Piper maineayti, Hook. f. Fl. Br. Ind. V.80(1885). Branches 
glabrous, fuscescent when dry, the spiciferous 1-5 mm. thick; 
collenchyma libriform in distinct bundles; several peripheric lysi- 
genous canals; a continuous zone of sclerosed cells tightly surround- 
ing the peripheric fibro-vascular bundles. Leaves moderately long- 
petioled, glabrous; limb thickly coriaceous, 10:5—13 cm. long, 
5'3—6'5 em. wide, elliptic-lanceolate, the base equilateral: 5-pli- 
nerved, the central nerve emitting 2 ascendent nerves, the uppermost 
from 3°9—5°5 cm. above the base, and having on each side of it 
one ascendent nerve free from the base; petiole up to 8°5 mm. long, 
sheath basal. Peduncle a little longer than the petiole, finely 
tomentose as are the rhachis and receptacles. Spike: 3 nearly 42 
mm. long, densely velutino-puberulous ; the receptacles stipitate, 
loose, rounded, 1:5 mm. in diam., densely velutino-puberulous 
outside and inside, 3—5-androus; anthers ovate, 4-valvate, shorter 
than the filaments: ¢ 5:3 cm. long; receptacles sessile, rounded, 
densely velutino-puberulous outside and inside. Berry globose, 
about 6 mm. in diam. 
SINGAPORE AND Maxacca: Maingay K.D. 1334, 1336. 
The leaves are like those of P. firmum, but the spikes, by their pubes- 
cence, are very different from those of that species. 
66. PIPER RARISPICUM, C. DC. in Records Bot. Surv. Ind. VI. 27 
(1912). Branches glabrous, blackish when dry, the spiciferous 1 mm. 
thick; collenchyma continuous, libriform; a central and many 
peripheric lysigenous canals. Leaves moderately long-petioled, 
glabrous; limb 10°5—13 cm. long, 5°8—7 cm. wide; ovate, acutely 
and rather shortly acuminate, the base rounded and slightly inequi- 
lateral; 7-plinerved, the central nerve emitting 2 ascendent nerves the 
uppermost from 14:°5—16°5 mm. above the base, and having on each 
side of it 2 nerves free from the base, the inner ascendent the outer 
subascendent, much shorter and thinner than the others: petiole 
145—19 mm. long. Peduncle slender, glabrous, 29 mm. long. 
Spike: 3 rarely seen, 5°9 cm. long; rhachis puberulous ; receptacles 
stipitate, elliptic, velutino-pubescent outside and inside, diandrous ; 
anthers obovate, 4-valvate, about 0°5 mm. long, the oblong filament 
of same length.
