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

 Macromeria, there is, it I mistake not, a dimorphism of the flowers, affecting the form and 

 length of the corolla and filaments.

Lithospermum angustifolium, Michx. 



Pentalophus longiflorus, a. DC. 



Echinospermum patulum, 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 flatfish, tuberculate; 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 ifattish 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." —
