434 CYCADE.^. [part ii. 



ORDER CLXXVIL— CONIFER-E. (See Chap. XII. P. 205.) 



The male and female flowers are both pro- 

 duced in catkins, and both consist only of scales. 

 The pollen of the male flowers is very abun- 

 dant, and is discharged freely in fine weather. 

 The female flowers form cones, consisting of 

 numerous scales, at the base of each of which 

 are two winged seeds. The timber abounds in 

 resin. 



ORDER CLXXVIir.— CYCADE.E. (See Chap. XII. P. 229.) 

 These singular plants have thick timber-like 

 trunks, yet they can hardly be called trees, as 

 they increase in height by a single terminal 

 bud. The leaves are pinnate, and they unroll, 

 when they expand, like those of the ferns. 

 The male flowers are in cones, and the female 

 ones either in cones, or produced on the margin 

 of contracted leaves. The principal genera are 

 Zamia and Cycas, and one species of the latter 

 yields a kind of sago ; the true kind being a 

 product of a species of Palm.
