Onosmodium molle, Michx. In this, as I have observed in the too closely allied genus 

 Macromeria, there is, if I mistake not, a dimorphism of the flowers, aifecting the form and 

 length of the corolla and filaments.

Pentalophus longiflorus, a. DC. 



ECHINOSPERMUM PATDLUM, Lehm. 



EcHiNOSPERMUM (Lappula) Fremontii, Torr. (n. sp.) : "Stem erect, branching above ; leaves 

 oblong-lanceolate, clothed with stiff, incumbent hairs ; fructiferous pedicels erect ; disk of the 

 nutlets flattish, tubereulate ; prickles in a double series, slender, the interior ones longer than 

 the diameter of the nutlets — differs from E. patulum in its double row of prickles, and con- 

 siderable larger fruit : from E. Lappula in the much longer prickles and flattish disk, which 

 often has a number of small prickles along the axis. Colonel Fremont collected this plant in 

 his second journey (1844) on Pass creek, near the southern extremity of the Sierra Nevada." — ■
