covered with dense brown tomentum, the points of the 
comb-teeth and the inner face of the upper ones being more 
or less smooth, Lamina approaches to that of C. revoluta, 
deeply pectinate, laciniz subulate, tapering into spinous points. 
Fruits 2 to 4 alternating under the lamina, roundish, ob- 
long, more or less angular from pressure, rich yellow, and at 
the apex, bearing a perforated mammilla. 
Cycas revoluta. Thunb. agrees with (judging from Sir J. 
Smith fig. Linn. Trans. VI. t. 29, 30) C. pectinata in head of 
fruit, but the packing is not so close as to conceal all the 
fruit, as in C. pectinata, Then the hairs of the carpel, and the 
shape of the lamina are different, the pectines are irregular 
in direction, and deeper, some overlapping each other, lastly 
the fruit is hairy and red. 
Cycas spberica is distinguishable in the Botanic Gardens, 
by a more feathery look of the crown, due to the pinna being 
less thick and opaque, none of the specimens have attained 
the size of C. circinalis, two males of which are very fine, 
and several times branched.

The upper part between the pinnule of either side is 
dark green, nearly the colour of the pinnule, and has 
stomatose spots. The under } ditto is of the colour of the 
under half of the leaves, yellow green, and without stomata, 
although these organs only exist on the under surface of the 
pinnule.

* C. spheerica is distinct also in the shape of the male or anther scales.
