CYCADS. 
The Cycads resemble the palms in their iinbranched trunks 
and croAvning mass of folage, but in structure their naked seeds 
or oxiiles ally them to the Pines and Ferns. 
They are of two sexes: the male plants bearing cones of 
staminate flowers not unlike those of a spruce tree; the female 
naked ovules in the angles of small rusty downy leaves. 
Economically they are of value from the rich starchy char- 
acter of the pith and seeds, and their fronds are much used for 
decorations. 
Their popular name — sago palms — is a misnomer as they 
do not produce the sago of commerce.
