in the foregoing. The bract is smaller, lioweTer, aad the 

 scale attached to it soon becomes very large, thick, and 

 woody (Figs. 389, 290, and 391). The bract and scale in 

 this case have nearly the same relative proportions when 

 young as they have in the mature

In other cases, as in Gallitris 

 quadrivalvis, the axis is short, 

 and the phyllomes {d, Fig. 294) 

 which bear the ovules are only 

 four in number (Fig. 294, Ks,

It appears m the axil of a foliage/} 



leaf, and is a scaly axis, resembling a small cone (C, Fig. 

 284). The lower scales do not, however, bear ovules, and 

 at the top of the axis is a single naked ovule {D and E, Fig. 

 284). This simplicity is carried a step further in Oinhgo, 

 where the female flowers are merely naked axes, which bear 



no bracts or scales, 

 and produce but two 

 ovules at their sum- 

 mits (Fig. 395, sh).* 

 The female flower 

 of Cycas revoluta is 

 a rosette of phyl- 

 lomes, which bear 

 some resemblance to 

 foliage leaves, being, 

 however, smaller,

* The morpliology of the flow(irs of Oiiikgo, as liere jriven, is by no 

 means satisfactory. Instead of the ovules being borne upon naked 

 axes, it is probable that they are in reality upon foliar organs— i.e., 

 either modified leaves, somewhat as in Oycas, or upon elongated homo-
