differences, I have thought it best to adopt the following 
. arrangement. 
In general habit the Cyathee may be viewed as analogous 
to those species of Phegopteris and Lastrea, having terminal 
vernation, and large compound fronds rising from an erect 
caudex, and as some have naked sori, and others a lateral 
indusium not differing from that of Lastrea, the arboreous 
habit and elevated receptacles are, therefore, the only points 
that technically distinguish them, but, in some cases, even 
» the elevated receptacle fails. 
The apparent obliquity of the rmg of the sporangia in 
Cyathec has been already explained at page 4l.

Cyathea sp., Hook. Sp. Fil. 
Vernation fasciculate, erect. Oaudex slender, 3 to 5 feet 
high. Fronds simple, pinnate, or pipinnatifid, 2 to 8 feet 
long, smooth, glossy, pinns articulated with the rachis. 
Veins pinnately forked; venules free. Sori medial. Re- 
ceptacles globose. Indusiwm calyciform, ultimately deeply 
laciniated.

Ons, With regard to this genus Mr. Brown remarks in 
the “ Prodromus Flore Nove Hollandis," that, besides the 
genuine species of Cyathea, characterised by having the sori 
peated on the fork of the veins, there are others from 
Malacca, which have the sori seated on the middle of the 
. veins, which distinction I find normal to at least three 
 Speeies. It is, however, observed that in several species 
of true Cyathea the sori are seated a little above the
