DESCRIPTIONS OF THE SPECIES 
297 
Kunze makes three species, viz. : 
11. G. polypodioides Sm. 
12. G. glauca Sw., with varieties 
| A. normalis. 
|B. nudiuscula. 
13. G. argent ea Klf. 
He remarks, however, that G. polypodioides appears to 
belong to G. glauca , and that G. argentea is intermediate 
between them. Later authorities maintain G. argentea as a 
variety of G. polypodioides , and omit G. glauca ; but Baker 
recognises only one form. Some specimens have longer pin- 
nules, some are more glaucous, and some have the rachis quite 
set with woolly, ferruginous shag, while others are naked ; but 
all these conditions can be found in one clump, and are caused 
by surrounding circumstances: and though in dried specimens 
they may appear distinct forms, still in growth they cannot be 
separated.
