differences, I have thought it best to adopt the following 

 arrangement. 



In general habit the Cyatlicce 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 ring of the sporangia in 

 Cyathece has been already explained at page 41.

 Cyatliea sp., Hook. Sp. Fil. 



Vernation fasciculate, erect. Caudex slender, 3 to 5 feet 

 high. Fronds simple, pinnate, or bipinnatifid, 2 to 8 feet 

 long, smooth, glossy, pinnae articulated with the rachis. 

 Veins pinnately forked ; venules free. Sori medial. Re- 

 ceptacles globose. Indusium calyciform, ultimately deeply 

 laciniated.

OBS. With regard to this genus Mr. Brown remarks in 

 the " Prodromus Florae Novas Hollandia3," that, besides the 

 genuine species of Cyaihea, characterised by having the sori 

 seated 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 

 species. It is, however, observed that in several species 

 of true Cyathea the sori are seated a little above the
