belong to the type called Catkins, and become Strobiles 

 only when the seeds are approaching ripeness. The 

 word Cone is employed with almost the same meaning 

 as Strobile, though in general almost restricted to the 

 fruits of the Coniferce, while the latter word also in- 

 cludes the fruits of the Hop, and of a few other plants.

 Scales separating, showing woody Bracts expanded into a

The Strobile is the result of the fertilisation of several 

 flowers (there is usually one in the axil of each of the 

 bracts of which it is composed) ; but the flowers are in 

 most cases completely hidden from sight by the bracts. 

 The latter become much enlarged as the seeds are

ripening. They remain thin and membranous in some 

 plants, e.g., Hop (see Fig. 547). Among the Coniferce, 

 they usually become woody and hard ; in some, e.g., 

 Cedrus (see Fig. 548), they remain comparatively thin; 

 but in others, e.g., Gupressus (see Fig. 549), each bract 

 expands towards the tip into a broad, shield-like plate.

In the genus Juniperus, the bracts become soft and
