not, tLciefore, be ignored auy more than other volumes of a 

 botanical nature. The latin names are either uninomials, bi- 

 nomials, or polynoniials. The work contains no generic descrip- 

 tions as such but the Latin names are accompanied by descrip- 

 tions supi)leniented, in some instances, by illustrations, so that 

 there is no (pieslion as to the identity of the plant described, thus 

 making- the publication effective according to Article 35 of the 

 Vienna Code. On pages 171 & 172, in the order given herewith, Hill 

 described two si)ecies ; Male Fern, Filix mas and Female Fern, Filix 

 Focinina. The male Fern is the species known as such at the pres- 

 ent time. The Fenmle Fern is the one that was i)ublished by Linne as 

 Ptcri,^ aqnUiud. The names Filix mas and Filiw foemhia as here 

 used by Hill must be considered as true binomials and not in any 

 sense as generic names as employed by him a year later in the 

 British Herbal. Since the binomial has been effectively published 

 it follows that each element of the binomial, that is to say, that the 

 generic name and the specific name each has been effectively pub- 

 lished and the proper citation for the genus is Filix (Fuchs) Hill, 

 Family Herbal 171, 1755.
