can clearly be made out and recognised, and, if the picture is a good 

 one, all the characteristics of the plant can be observed. But a 

 picture can never show the special characteristics alone, which raise 

 the genus above the other of its affinity. A genus only gains 

 priority by a verbal diagnosis, and nomina nuda and seminuda are 

 to be rejected ; therefore the following works cannot claim a right 

 of priority :— Rumphius, Herbarium Amboinense (1741-1755) ; Bur- 

 mann, Flora Indica (1768); Patr. Browne, History of Jamaica (1750); 

 Lamarck, Illustration des Genres pro parte, &c. 



Ad III. There are to be conserved Adenia as well as Adenium, 

 Acnista as well as Acnistm, Alectra as well as Alectryon, Apios as 

 well as Apium, Rubia as well as Eubus, Belli* as well as Bellium, 

 thlnris as well as Chlorea and Chlora, Glypfum as well as G/t/plus 

 and Glyphia, Calopoynn as well as Calopoyonium, Atropa as well as 

 A tropin, Galax as well as Galaxia and GaUtctia, Danae as well as 

 Danais, Drimia as well as Drimys, Glechoma as well as Glechon, 

 Hydrothri.r as well as Hydrotriche, Micranthm as well as Micrantheum, 

 Microtea as well as Mcrotus, Phttystemma as well as Platystewon, 

 Silvaa as well as Silvia, &c. ; we doubt that there is any scholar 

 who will confound them. On the contrary, Tetraclis and Tetracleit, 

 Oxythece and Oxytheca, Epidendrum, and Epidmdrov, Oxijcoccm and 

 Oxycoecos, Asterocarpus and Astrocarpus, Peltostema and Peltistema 



are only different modes of spelling the same word, and the newer 

 one is to be refused, if they name different genera. 



• i Ad * IV * Tlie im P ulse that led to the acknowledgment of the 

 right of priority was only the vivid desire to create a stabile nomen- 

 clature. If we see that by the absolute and unlimited observance of 

 the principle we probably gain the contrary of what we intended, 

 we, who have ourselves made the rules of priority as a law, have 

 the right to amend the latter. Therefore we present a list of genera 

 that have more than a merely scientific interest, or that are very 

 large, and we propose to conserve them in spite of the rules of 

 priority, in order to avoid a general confusion by the change of 

 many thousand names. °
