BRANCHLETS OF CHARES 

 (RAMULI). 



phlceopodes = branchlets 

 with the lowest seg- 

 ment corticate. 



gymnopodes = branchlets 

 with the lowest seg-

 above corticate. 



podophora= bearing sexual

 node. 



podosteira = baving the 



lowest free node sterile. 



* As explained on page 25 we cannot regard the branchlets as leaves, hence 

 we have substituted 'clema' for ' phylla' in this and the following terms.
