266 UNDERWOOD : REVIEW OF THE GENERA OF FERNS 
This is a case where a proper exception may be made to the rule 
of accepting the first name cited under the genus as the type, since 
a definite type was previously mentioned by the author of the 
genus in the description. 
1804 
Sprengel (Anleitung, 3:) described several species in various 
previously established genera of which he recognized thirty-two, 
but established no new ones. 
1806 
Bernhardi (Schrader's Neues Journ. 1?*:) published the follow- 
ing genera: I. Cystopteris (26) based on Aspzdium fragile, A. mon- 
tanum, and A. bulbiferum; 2. Hypolepis (34) based on Lonchitis 
tenuifolia Forst. ; 3. Allosorus (36) based on “Alle Adianta spuria 
SW. Lier enipiebis (38) based on Polypodium dichotomum ; and 
4. Ornithopteris (40)t founded on certain Osmundae ‘ welch einen 
gyrus spurius besetzen," of which O. hirsuta and O. adtantifolia 
are mentioned. 
1806 
Swartz published his Syzopszs Filicum which was the first com- 
pleted systematic review of the ferns of the world.{ Swartz’ 
* The ** Adianta spuria’’ of Swartz (Schrader’s Journ, 1801) are A. viride (Pteris 
viridis Forsk.), A. microphyllum imer. E tos y A. abe reed us da de

panting of the genus Cheilanthes in Swartz’ Synop. Fil. (p. 126) and the printing of the 
index (p. 425), which says ** A//osorus Bernh. est' Cheilanthes.’ TIn so close and com- 
plicated a case as this it would seem reasonable to let the genus Cheilanthes stand, es- 
pecially since Pteris viridis Forsk., the first named species under A//osorus, is not a 
Cheilanthes. For the same reason A//osorus must hold for a good genus 
spec 
which a lack of system in systematic work has br 
T This is also disposed of in the index of Swartz Sosa Filicum as ** Ornith- 
—À Bernh. est Anemia.’’ It would seem that this antedates Anemia and may stand, 
parti: as its type is in a different section of the composite genus which has hitherto 
been divided perhaps with good reason. 
1 Poiret did not complete his account of the ferns whi Lamarck 
in i783 in the iu ngu Methodique until 1808. ac described rig PER species; 
Swartz described 716 species besides cun e with 68 
Lycopodiaceae.
