 logus plantarum hispanicarum, etc. ab A. Blanco lectarum, Parisiis, Jul. 1850 in folio). — Non-effective 

 pulilication at a public meeting: Cusson announced bis establisbment of tbe genus Physospermum 

 in a memoir read at the Société des Sciences de Montpellier in 1773, and later in 1782 or 1783 at 

 the Société de Médecine de Paris, but its effective pulilication dates froni 1787, in the Mémoires de

 a complète specific or varietal name, liut without diagnosis or référence to a former

 of name on a ticket issued with a dried plant without printed or autograjjhed diagnosis.

 applies only to plates published before January 1, 1908.

 synonym of Micropteryx Poeppigiano Walp. in Linnaca XXIII, 740 (1850) is not a valid pulilication ;

 O. F. Cook in U. S. Dep. Agr. Bull, n« 25, p. 57 (1901); Nepeta Sieheana Hausskn. which appears 

 without diagnosis in an exsiccata (W. Siehe, Bot. Reise nach Cicilien, n» 621, 189()), is not valid. 



Art. 38. A genus or any other group of higher rank than a species, nained 

 or announced without being characterised conformal)ly to article 37 cannot be regarded 

 as effectively published {iiomen niidiim). The mère indication of species as belonging 

 to a new genus or of gênera as belonging to a higher group, does not allow us to 

 accept the genus or group in question as characterised and effectively publisheil. An 

 exception is made in the case of the generic names mentioned by Linnaeus in the 

 Species Plantarum éd. 1., 1753, names which we associaîe with the descriptions in 

 the Genera Plantarum éd. 5.. 1754 (See article 19).
