138 THE JOUKNAL OF UOTANY 



Muell. but as Himantandra is invalid, the genus should be known 

 as Galbulimima. The synonymy and distribution of the sj)eeies 

 liitherto described are as follows : — 



GrALEULTMiMA BACCATA. F. M. Bailev in Queensl. Dep. Agric., 

 Bot. Bull. ix. 5 (1894) -Queensl. Fl. 19; ComiDr. Cat. Queensl. PI. 25.

Names which are suggested in advance for groups which might 

 possibly be recognized in the future may be known as '• nomina 

 provisoria." The publication of snnilar names is deprecated in 

 Recommendation XIX : " Botanists will do well to avoid publishing 

 or mentioning in their publications unpublished names which they do 

 not accept." 



16. A wrong determination cannot he treated as a valid name, 

 nor serve as the hasis for a new combination. — A similar Kule has 

 been proposed by Schinz and Thellung : " Ein Name soil nicht als 

 giiltig (oder zur Bildung neuer Kombinationen prioritatsberechtigt) 

 anerkannt werden, wenn er sich auf die unrichtige Verwendung eines 

 bereits bestehenden, fiir die Nomenklatur der betreffenden Gruppe 

 massgebenden Namens bezw. auf eine falsche Bestimnmng grundet, 

 selbst wenn jener altere homonyme Name heute nicht mehr als 

 giiltig verwendet wird " ( Vierteljahrsschr. Nat. Ges. Ziirich, Ixvi. 513). 



Numerous instances of wrongly-applied names of species are cited 

 by Schinz and Thellung. Some examples of incorrect application of 

 generic names may be given. 



Munro erroneously referred seven South African species to Ach- 

 neria Beauv. (Harv. Gen. S. Afr. PL ed. 2, -149; 1868). Bentham 

 reduced AcJineria Beauv. to Eriachne M. Br., from which it had 

 originally been segregated, and treated the South African species as 

 constituting an independent genus, for which he unfortunately 

 retained the name Achneria, attributing it to Muni-o. '• Achneria " 

 in this sense has been accepted in the Flora Oapensis, and hj Dalla 

 Torre et Harms. But Munro did not propose a new genus ; had he 

 done so he would have given it a new name. What he did was to 

 identify the group with Achneria Beauv. As this identification is 

 admittedly incorrect, the genus must be re-named, and may be known 

 as ArEACHNEiiiA (nom. nov.). 



J. D. Hooker erroneously referred to Alepyrum P. Br. a New 

 Zealand plant which he had j^reviously described as Gaimardia 

 pallida (Fl. N. Zeal. i. 268; 1855). When Hieronymus mono- 

 graphed the family GentrolepidacecB, he treated Alepyrum P. Br. as 

 a synonym of Ceutrolepis, and based a new genus on Gaimardia 

 pallida. Instead, however, of proposing a new name for the genus 

 he called it Alepyrum Hook. f. ex parte, non P. Br. (Abh. Nat. Ges. 

 Halle, xii. 217; 1873). Baillon replaced Alepyrum pallidum in 

 Gaimardia, and made it the type of a new section, Alepyria, so- 

 named to avoid confusion with Alepyrum P. Br. (Jkdl. Soc. Linn.
