Sub-class II. Gymnospermous. 



Ovules produced superficially on a scale (bract or open ovary) ; fertilized by the direc 

 application of the pollen to the apex of the nucleus, which the pollen-tube penetrates. 

 Flowers unisexual (except in WehvitscMa). 



223. CONIFERS. Stem branched, exo- 

 genous, with slender pith and no proper 

 vessels (vascular tissue proper). Leaves op- 

 posite whorled or fascicled, simple; nerves 

 simple. Perianth 739 



223a. GNETACE.E. Stem branched, exo- 

 genous, or tissues confused, with slender pith 



and proper vessels. Leaves or opposite; 

 nerves branched (except Welwitschia). Peri- 

 anth of bracts or scales ....
