Hab. Shores of Puget Sound, and interior of Washington Territory ; 

 southward to San Diego, California.— In the Botany of the Mexican 

 Boundary I remarked that perhaps all the species of this genus 

 with rugose nutlets may be forms of A lycopsoides. Whatever doubt 

 may yet remain on this subject, I believe that all the other species of 

 De Candolle's Profovmua, with the exception of A. vernicosa (which is 

 easily distinguished by its perfectly smooth, shining, and acute nut- 

 lets), may be reduced to a single one. The nutlets vary considerably, 

 and are sometimes scarcely at all rugose on the back. No doubt A. 

 Douglasiana of Alph. De Candolle is the same as A. spectabiUs of Hooker 

 & Arnott. Specimens of A. angustifolia (from Valparaiso, Matthews) 

 given to me in 1833 by Lindley, cannot be distinguished from what 

 has been called A. intermedia of California. No dependence can be 

 placed on the position of the stamens in the tube of the corolla, as I 

 have shown in the Botany of Whipple's Report, p. 124. 



7. PIPTOCALYX, Nov. Gen. 



Calyx cequaliter o-fidus, infra medium transverse deciduus, basi persistente 

 membranacea obtuse 5-dentata. Corolla tubuloso-infimdibidiformis, 

 fauce nuda. Stamina 5, inclusa: filamenta medio corollas inserta: an-

 convexce, angulo interno stylo in/erne adnatce. Stylus brevissimus ; 

 stigma capitellatum. — Herba Calif or nica, pusilla, ramossima, annua; 

 foliis linearibus ; floribus in cymulis foliosis brevissimis terminalibus.
