64 EEYTHEA. 



Messrs. John M. Coulter and J. N. Rose, who Lave worked 

 together to large advantage on the Umbelliferse of the 

 United States, have been making incursions into fields 

 beyond our borders. In " Contributions from the United 

 States National Herbarium," Vol. III. No. 5, they present a 

 report on Mexican Umbelliferae, mostly from the State of 

 Oaxaca, recently collected by C. G. Pringle and E. W. 

 Nelson. The material afforded by the collection " enabled 

 [them] to establish 4 new genera and 27 new species." The 

 new genera are Coaxana, Deanea, Neogoezia and Neonelsouia. 

 The derivation of the first of these names is not given. While 

 this is not a matter of moment the origin of a name is always 

 of interest. The new species belong mostly to Museniopsis, 

 Eryngium, Arracacia and Angelica. The generic characters of 

 Museniopsis are laid down anew and the distinctions drawn 

 between this genus and Eulophus, Arracacia and Velaea. In 

 the same number the rare Angelica verUcillaia, Hook., is 

 figured which Mr. Rose refers to Ligusticum. Two new 

 western species are figured and described: Ligusticum 

 Eashvoodae from Colorado and Velaea glauca (hitherto 

 considered as a glabrous form of V. Kelloggii) from Oregon. 

 This report certainly contains no scant harvest and is one of 

 the most important of recent contributions to the knowledge 

 of American Umbelliferae. Nevertheless, we wish that 

 Messrs. Coulter and Rose might devote their combined 

 energies primarily to the elucidation and illustration of the 

 species north of the Mexican boundary, for there are wide 

 fields ungarnered and few workers fitted for the task. 



In the Bulletin of the Torrey Club for January, Dr. John 

 K. Small offers two new genera of Saxifragaceae, viz., 

 Jepsonia, founded on Saxifraga Parryi Torr., and including 

 Saxifraga malvsefolia Greene, and Saxifragopsis, the type 

 being Saxifraga fragarioides Greene. In the same number 

 Prof. E. L. Greene describes as new Saxifraga fallax from 

 Lassen's Peak and renames S. umbellata Greene (not of 

 Hook. f. & Tlioms.), as S. aprica.
