274 UNDERWOOD: REVIEW OF THE GENERA OF FERNS 
1828 
J. E. Smith (Engl. Flora, 4: 258) established the genus Cyszea 
founded on C. fragilis and three other British species, and thus 
introduced the practice of arbitrarily discarding a name already 
established, “a retrenching of the genus Cystopteris Bernhardi as 
compounded of another already established, Pteris, neither the 
genus or [sic] its name having ever been received, such a neces- 
sary correction can cause no inconvenience." It is a sufficient con- 
demnation of this egotistic assumption to note that the name 
Cystea has received the merited oblivion it deserves and only its 
mummy remains in synonymy to remind us that justice in nomen- 
clature is sometime sure to come! 
1828 
Wallich ( fide Sprengel : Gen. Pl. 724) established Arthrobotrys 
as a subgenus of Aspidium based on A. Thelypteris and several other 
species. Pfeiffer dates the genus 1831. In his catalogue (1832) 
he established Actinostachys based on Schizaea digitata. 
1828 
Blume (Fl. Javae, 2:*) established Pleurogramme (69), based 
on Taenitis linearis Kaulf., T. pinnata Kaulf. and T. graminifolia 
Hook.; Chetlogramme (70), based on T. lanceolata Kaulf., 
angustifolia Spreng., T. furcata Willd., and T. tricuspidata Spreng.; 
Loxogramme (7 3), as a subgenus of edini based on G. lanceo- 
lata Swz., G. coriacea (Kf.) Spreng., G. avenia Blume, and G. in- 
voluta pos: Under Polypodium he also establishes the § Gontio- 
phebium (132), based on P. cuspidatum, P. subauriculatum and ? P. 
pallens ; and § Cfenopteris (132) based on seven species of which 
P. Celebicum is first named. 
1829 
Kaulfuss (Flora, 12': 341) established the genus Physematium 
based on P. molle from Mexico, a genus, perhaps, needlessly sepa- 
rated from Woodsia. 
* The copy of this folio in the Columbia University bears the double date ** 1828- 
36” but the genera are usually assigned to the earlier date whether correctly we 
cannot say.
