July, 1915. The Queensland Naturalist.

both in colour and form. Each plant only sends up one 
pair of fronds a year, one fertile and the other sterile. At 
the end of last November, in company with Mr. White 
and Mr. Young, I took several specimens at Wellington lk)int. 
The fronds which were then on the plants soon died away, 
and they have each just sent up their two new fronds. It is 
easily grown in fairly light well-drained soil. 
Now, I feel sure that this paper is getting monotonous, 
and though I have by no means exhausted the list of cul- 
tivable ferns of Southern Queensland, I will bring it to 
a close. Still, it would be quite incomplete did 1 not allude 
to the deservedly popular Adicmtmn or Maiden Hair family. 
Of these A. Aethiopicum is undoubtedly the best one to 
grow, as not only is it the easiest to grow, but it compares 
most favourably with many of the imported glass-house 
varieties. It may be obtained on the slopes of the ridges 
at the back of Mount Cootha, but it grows in much greater 
profusion on the ranges near to 'Foowoomba. 
Adiantum Fonnosum, the giant Maiden Hair of the 
scrub also grows well under cultivation, but must have more 
shade than the other variety. It. however, is not so easily 
transplanted, as its so-called root runs some six or eight 
inches under the ground, and almost always amongst rocks. 
This, added to the fact that it is softly brittle, makes it a 
labour of patience — I might almost say a labour of love — 
to obtain sufficient to make a good showing. But when once 
it is established it grows very luxuriantlv. 
Adiantum hispidulum is the most commonly met with 
form of this genus, and grows in almost every dry gully. 
It is very hardy, and can, therefore, be readily transplanted. 
Very often, especially when exposed to the sun, its young 
fronds are very red or pink.
