268 UNDERWOOD: REVIEW OF THE GENERA OF FERNS 
Hort. Kew, alias sp. ineditas continet." 2. Allantodia* (149) 
based on A. australis and A. tenera. 3. Doodia (151) based on 
D. aspera, D. media and D. caudata. 4. Stegania (152) based 
on eight species of which S. Paterson? is first named ; the species 
are included under Lomaria by Baker. 5. Alsophila (158) based 
on A. australis, 6. Platyzoma (160) based on P. microphyllum. 
In a footnote under Alsophila, Hemitelia (158) is proposed for 
Cyathea multifiora Swz., C. horridaand C. Capensis, and in a second 
footnote for Polypodium Ilvense and P. hyperborea, Woodia (sic) is 
proposed.

Humboldt and Bonpland (see 1810 under Willdenow). 
1810 
Willdenow published the fourth edition of Systema Plantarum 
of which Vol. 5 contains the ferns in which 43 genera and 1008 
species are recognized; the new generaare: I. Ceterach (136) based 
on three species of which C. offtcinarum is first named, a changed 
form of the name of a genus, long before adopted from Tourne- 
fort by Adanson; 2. Pleopeltis H. & B. (211), based on P. an- 
gusta ; and 3. Polybotra H. & B. (99) based on P. osmundacea. 
1811 
Desvaux (Berliner Mag. 5:) established the following genera : 
. Didymochlaena (393) based on D. sinuosa Desv. from 
India orientalis. 
2. Gymnogramma (304) based on G. rufa (Pteris rufa) from 
Jamaica and twelve other species. 
- 3. Cincinalis (311) based on C. ferruginea Desv. of the Antilles 
and eleven others. 
4. Cyclophorus (300) based on C. adnascens (Poly. adnascens 
Swz.) and five others. 
These were repeated in the Jour. de Bot. 1813. 
* The inconsistencies of English systematists are forcibly illustrated here; this 
„genus of two species has been returned to Asplenium while the generic name has been 
transferred to 4. Brunoniana, and the genus ascribed to be eee Cf. Synopsis
