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 flattish, 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 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.”—
