tlie use of the same name foi' anj' subsequently published genus or species, 

 respectively. 



"Bale 6. — Publication of a genus consists only (1) in the distribution 

 of a printed description of the genus named ; (2) in the publication of the 

 name of the genus and citation of one or more previously published species 

 as examples or tj'pes of the genus, with or without a diagnosis. 



" linle 7. — Publication of a species consists only (1) in the distribution 

 of a printed description of the species named ; (2) in the publishing of a 

 binomial, with reference to a previously published species as a type. 



" Hide 8. — Similar generic names are not to be rejected on account of 

 slight differences, except in the spelling of the same word. 



"Rule 9. — In the case of a species which has been transferred from 

 one genus to another, the original author must always be cited in 

 parenthesis, followed by the author of the new binomial. 



" Hale 10. — In determining the name of a genus or species to which 

 two or more names have been given by an author in the same volume, or 

 on the saine page of a volume, precedence shall decide." 



Among the alterations in nomenclature are a few which affect 

 oiir British list. This will, we fear, distress our good friend Mr. 

 Clarke ; but it seems probable that in the next London Cataloyue 

 the following changes will be necessary* : — 



Juncoides Adans. (1763) for Luzula DC. (1805). 

 — Unifolium Adans. ,, ,, Maianthemum Wigg. (1780). 



Gyrostachys Pers. (1807) ,, Spiranthes L. C. Rich. (1818). 

 -Peramium Salisb. (1812) ,, Goodyera Br. (1813). 

 ^Savastaua Schrauk. (1789) ,, Hierochloe Gmel. (1747).- 

 _^Dondia Adans. (1768) ,, Suaeda Forsk. (1775). 



SucBchi maritima becomes Dondia innritiina Driice — a name which 

 Mr. Druce published in his much-criticised paper in the Annals of 

 Scottish Xat. Hist, for 1896. We demur, however, to the super- 

 session of Elodea Michaux (1803) by Philotria Raf. (1818), which 

 is rendered necessary by the application of Rule 8 ; and w^e cannot 

 think that botanists will agree to accept Rule 5, under which we 

 suppose it is that Nartlierimn becomes Abunui. We think some 

 hesitation is justifiable as to the adoption of Lcptorchis Thouars 

 in place of Liparis. Prof. Britton refers to " Nouv. Bull. Soc. Plilom. 

 [sic] 314," meaning 317, where Thouars spells the name Leptoikis, 

 but excludes the two American species (one of which is L. Loeselii) 

 from it. Kuntze adopts the name, and, vwre sua, sweeps into the 

 genus a vast number of species by the simple process of substituting 

 Lejitoichis for Liparis. On the other hand, Jackson does not recog- 

 nize the genus, and we believe there is some doubt as to the actual 

 position of this and the other names given by Thouars. 



We are sorry that Prof. Britton has felt compelled to yi^d to 

 "the general desire" for what are called " English names," and 

 regret still more that a mistaken purism leads bim to reject so old 

 a name as "Dog's-tooth Violet" for Lri/thronimn, on the ground 

 that it "is calculated to mislead as to the nature of the plant." He 

 even goes so far as to say "the species are erroneously called Dog's-

antedates D. stdlatnm Thuill. (1799).
