subterranean, but the imported stems now in cultivation at 
Kew, and shown in plate 8242, are similar in habit to those 
of other species of Cycas except in being more slender and 
in having usually a decidedly thickened base, 
Cutivation.—At Kew this species is not unlike C. 
pectinata in behaviour, the leaves being practically annual. 
It would appear therefore that the conditions most favourable 
for its healthy growth are a liberal allowance of root-room, 
a good loamy soil, a plentiful supply of water whilst the 
leaves are being formed, and a tropical temperature with 
abundant sunlight. In winter the soil about the roots 
should be kept drier. : 
Description.—Stem sometimes subterranean, 8 in.—2 ft. 
in height, 13 in. thick above, sometimes 4 in. thick at the 
base. Leaves 2-3, terminal, erect, 8-10 ft. long, their lower 
third beset with short rather flat yellow spines, elsewhere 
bearing two rows of subdichotomous pinnules 8 in. long and 
13 in. apart, their segments green above, paler beneath, 
3-1 in. wide, usually again divided. Male cone narrow- 
cylindric, on peduncles | in. long with a few narrow triangular 
acute bracts, the cones 6-7 in. long, 14 in. thick, with yellow 
glabrous subspathulate scales, orange at margin, } in. long, 
4 in. wide at the shortly apiculate apex. Carpophylls 3 in. 
long, with narrower yellow base and obovate-rhomboid green 
terminal limb 1} in. wide, deeply pectinately fringed.
