* The name Aspidium of Dioscorides is found as one of the synonyms 
of Alyssum Diosce. 1. 3, c. 95, and later as a synonym for Atractylis—Cmnicus 
sylvestris. 
+Dryopierts of Dioscorides, Pliny and Theophrastus is Aspleniwm 
Adianium nigrum Linn. The use of the name for the genus in question 
is therefore objectionable as used by Adanson and tmust be relegated to 
synomymy on the basis of historical pricrity. See Fée, A. de Théocrite. 
(Ds OQ. Swata” Ids, Mu (Cralees Icoyel, Aa aire ‘ 
tThelypteris of the Valerius Cordus and the other pre-Linnaeans is 
Pieris aquilina Linn, and essuming this plent to be the type of the genus 
Pieris, similar reasons to those of the preceding note invalidate the name. 
Likewise F2'ix is to be rejected as a name both for this and any other genus 
of ferns as it is but a latin form of the Greek P.er?s and was so used by 
Vergil and others. See Fée, A. Fl. de Verg. p. 56. According to Bauhin 
The'yp-eris of Theophrastus, Pliny end Tioscorides refers to A:hyrium. 
Fiix femina (Linn.) Roth or Aspenium Fiix jfemina (Linn.) Bernh. 
Regarding the name Lenchitis as a name for the genus there seers to be 
corsiderable doubt. See J. E. Smith Fl. Graec 2: 273, though Tourne- 
fort seems to have adopted the name, Inst. Rei Herb., 538. (1700).
