ceolate, sometimes elliptic-oblong, shortly acuminate at apex, or 
sometimes nearly obtuse, acuminate acute or almost rounded at 
base ; dark green when fresh, olive-green when dry, glabrous on 
both surfaces; margins entire; 8—25 cm. long, 3—10 cm. broad; 
midrib moderately stout, raised on both surfaces; main nerves 
12—20 pairs, thin but prominent and raised on both surfaces, curv- 
ing slightly to near the margin then rather abruptly to break up 
along it in small loops; transverse nervules very many, often 
branched or irregular, enclosing the areolate reticulation; petiole 
1°5—2 cm. long, swollen at base. Spikes slender, about 10—15 em. 
long, cinereous-pubescent, in long-peduncled terminal or axillary 
panicles, 3 very many, ? few, some androgynous the ° below 
the & above, sometimes the @ from the past year’s wood with 
stout rhachises, showing late development. Flowers: 3 solitary or 
in clusters of few together ; bracteole small, ovate, obtuse ; perianth- 
lobes 6, free, ovate-obtuse, very small, villous ; stamens 12, with 
slender filaments and minute globose anthers; pistillode very villous, 
pale, sometimes small: 2 in groups of usually 3, bracteoles 1 or 
more asin 3 ; perianth asin 3 but even smaller ; staminodes like 
minute stamens ; styles 3, spreading, villous at base. Fruits in 
thick woody spikes reaching to 20 and even 25 cm. long, when quite 
young depressed globose with prominent tubercles and more or less 
pedicelled, when older more or less lobed and constricted, the 
tubercles flatter, the pedicel less, when mature obovoid or globose, 
almost sessile, usually slightly constricted in 2—3 lobes, up to 2cm. 
high, 3 cm. long and 2—2-°5 cm. broad; cupule thick-walled, 
brittle, minutely grey-pubescent, bearing externally 3—5 irregular 
transverse rows or groups of short pyramidal tubercles, dehiscence 
irregular or not at all; ripe nuts 1—3, when 1 ovoid, when more 
ovoid-complanate, appressed sericeous except the rugose base which 
occupies one-third of the whole. A. DC. Prodr. XVI. ii. 113: Hook
