Nomenclatural Notes. 
1. Chedlanthes gracilis (Fée) Metten. This specific name, 
adopted in the A. A. A. S. “Check-list,” dates only from Fée’s 
Genera Filicum, 1850-52, while the name Cheilanthes gracilis was 
applied by Kaulfuss (Enum. 209. 1824) to the Preris gracilis of 
Michaux (Pellaea gracilis of Check-list, Pellaca Stelleri of Britton 
and Brown’s Flora). Moore, to avoid producing a homonym of 
Kaulfuss’ name, in transferring Fée’s Myriopteris gracilis to Chet- 
_ lanthes, called it C. Feei, which is the oldest available name for this 
species. Cheilanthes lanuginosa Nutt. was not published until the 
following year. The synonymy of this species thus stands as fol- 
lows: 
CuertLvantueEs Freer Moore, Ind. Fil. xxviii. Mr. 1857. 
Myrwopteris gracilis Fée, Gen. Fil. 150. 1850-52. 
Cheilanthes lanuginosa Nutt.; Hook. Sp. Fil. 2: 99. 1858. 
Chetlanthes gracilis Metten. Abh. Senck. Nat. re 3: [re- 
print 36]. 1859. Not Kaulf. 1824. 
2. Epifagus (Epiphegus) Nutt. This name is clearly antedated 
by Leptamnium Raf. Rafinesque’s name was published in Febru- 
ary, 1818. The date of publication of Nuttall’s Genera is not ex- 
actly known, but it must have been later than the middle of May 
of that year. The title was deposited to secure copyright on 
April 3; the preface is dated May 27; and it is quite certain that 
the work was all issued at the same time. It is true that Barton, 
in his Compendium Florae Philadelphicae, published before the 
end of the same year (1818) repeatedly cites Nuttall’s work, but 
in his preface he acknowledges Nuttall’s kindness in permitting 
its use, and it is by no means certain which work was offered to 
the public first. In any event, it appears to me, the priority of 
Rafinesque’s names, published in the January and February num- 
bers of the American Monthly Magazine, is unquestionable. The 
Synonymy of this monotypical genus is given here.
