I quite agree with 

 Collins and Hekvey 

 that the original speci- 

 fic name of this plant 

 ought to be adopted 

 because montagne,1.c. 

 p. 166, only honoris 

 causa, replaced the spe- 

 cific name given it by 

 Delile and called it 

 A. Delilei. 



The plant grows 

 in tufts formed of 

 creeping rhizome-like 

 terete stems from which the beautiful ostrich-feather-like erect shoots 

 arise. 



The creeping stems (Fig. 347a) are very irregularly ramified. 

 The branches consist of two kinds, either branches with continuous 

 growth or branchlets with definite growth and without ramification. 

 The branches grow out either to decumbent, creeping branches, con- 

 tributing in this way towards the ramification of the basal part, or

 erect shoots, b, end of a branchlet with rhizoids.
