Valerianacece. 



Valeriana Arizonica. — Glabra, semipedalis; caulibus e rhizo- 

 matibus repentibus crassiusculis erectis pra^ter radicalia 2-4-phyllis ; 

 foliis succulentis, radicalibus ovatis integris subintegerrimis (pollicari- 

 bus) paucisve secus petiolum longiorem 2-4-lobulati.s, caulinis subses- 

 silibus 3-5-partitis ; cyma glomerato-congesta ; corolla semipollicari 

 tubulosa, tubo in faucem sensim ampliato limbo quint iiplo longiore. — 

 Arizona; in mountains near Prescott, Palmer, 187G ; Santa Catalina 

 Mountains, at 7,000 feet, Lemmon. In character somewhat between 

 V. Sitchensis, Bong., and V. paucijiora, Michx. ; with the elongated 

 corolla of the latter. 



Valeriana sorbifolia, HBK., is an accession to the North 

 American flora, a form of it, mostly with unusually large and broad 

 leaflets, having been collected in a cafion of the Huachuca Mountains, 

 S. Arizona, by Lemmon, 2713, 2728. 



Valerian ELLA. In Torrey and Gray's Flora of North America, 

 the long-flowered species from Arkansas, forming the section Sipho- 

 nella, were judged to effect such a transition to Fedla that, following 

 Gaertner and Valil, Valerianella was reduced to Fedia. This was not 

 well ; for Valerianella is not only the older name, but one of numerous 

 published species, while there is hardly more than one true Fedia. 

 But the junction under the name of Valerianella, Tourn., Ilaller, &,c., 

 must needs be made, and Plectritis, DC, should be included. There 

 is now a species of the latter which has a spurless corolla ; the rudi- 

 ment of the spur, in the form of a small saccate or conical protu- 

 berance, is not uncommon in several of our Valerianellas, notably in 

 V. amarella, V. Ndttallii, and even V. longijlora ; while the Betckea 

 section has the wings of the fruit replaced by nerviform rudiments of 

 the sterile cells. The limb of the coi'oUa is not quite regular in the 

 Siphonellce, is either nearly regular or decidedly bilabiate in different 

 species of Plectritis ; so that nothing but the diandrous instead of trian- 

 drous flower is left to characterize Fedia. Whatever view be taken 

 of- that genus, it is evident that the American forms {Siphonella, Plec- 

 tritis, Betckea, the latter already united) all fall into one genus.*
