Sooner or later the apices of some of these leafless shoots turn upward, 
develop leaves, and become typical leafy branches upon which are borne 
the reproductive organs. 
Goebel thinks that the leafless branches arise from the apex of the 
young leafy shoots, but remain dormant until the shoot has elongated,

so that they seem to be of basal origin. This is contrary to Leitgeb’s con- 
clusions for Haplomitrium , where he says there is no terminal branching, 
and that all the branches are intercalary in origin. 
The writer has not made a critical study of this point, but from a 
somewhat careful examination of a number of much-branched rhizomes he
