a) A specific or subspecific name is a hyponym when it 



has not been connected with a description identifiable 



by diagnostic characters or by reference to a type 



figure, specimen or Iocality. 



Examples. — Gentiana hybrida Raf. Med. Rep. II. 5: 353 

 (1808), is a hyponym, as no diagnosis is published; Lechea fur- 

 furacea Raf. New FI. Am. 1 : 92 (1836), is a hyponym, as its de- 

 scription is not identifiable. 



b) A generic or subgeneric name is a hyponym, when it 

 is not associable, at least by specific citation, with a 

 binominal species previously or simultaneously publi- 

 shed; or when its type species is not identified. 



Examples. — Adodendrum Necker, Elem. (1790), and Pon- 

 gelion Adans. Farn. PI. 2: 319 (1763), are hyponyms, because 

 their authors neither named a binomial species nor cited a 

 species which had previously received a binomial name; Nudilus 

 Raf. Atl. Jour 176 (1833) is a hyponym, as its type species, 

 N. paradoxus, has not been identified. 



Part III. Orthography and Citation. 



Section I. Orthography. 



1. The original orthography of names is to be maintained, 

 except in the following cases; the change not to affect 

 priority. 



a) Manifest typographical errors may be corrected. 



Examples. — Scoria Raf. is a misprint for Hicoria; 

 Rumhora Raddi is a misprint for Rumohra, named for C. de 

 R u m o h r. • 



b) Adjectival names of species and subspecies agree in 

 gender with the generic name with which they are 

 associated. 



Examples. — Polygomim articiilatum L. — Polygonella 

 articulata (L.) Meissn. ; Sisymbrium amphibium palustre L. 

 = Roripa palustris (L.) Bess. 



c) Generic names derived from personal names should 

 be feminine, and if originally of other forms should 

 be corrected. 



Examples. — Lippius S. F. Gray, Kantius S. F. Gray, 

 Pallavicinius S. F. Gray, should be changed to Lippia, 

 Kantia, and Pallavicinia and yet date from 1821 when ori- 

 ginally published. 



d) In the case of names proposed in works in which 

 v and j were used as vowels or u and i as conso- 

 nants they should be corrected to agree with modern 

 usage. 



Examples. — Euonymus, not Evonymus; Naias, not 

 Najas; Neuropteris, not Nevropteris ; Rivularia, not Riuu- 

 laria (Rivvlaria); Jungia not iungia. 



2. Generic names should be written with initial capital 

 letters. 



Examples. — Desfontainea, not des Fontainea ; Durvillaea 

 not D'Urvillaea. 



3. If capital letters are to be used for specific names they 

 should be only for substantives and for adjectives deri- 

 ved from personal names.
