simple or nearly so, puberulent even when mature : leaves with 

 a glaucous hue, puberulent or often so only on the margins, 

 both leaves of the pair ascending on the upper side of the pros- 

 trate stem, causing it to appear one-sided, i. c, naked on the 

 lower ; root-leaves small or none ; lower stem-leaves spatulate- 

 oblong, sessile or with margined petiole, 4-7 cm. long, mostly 

 obtuse ; upper stem-leaves lanceolate, 7-10 cm. long, sessile by a 

 broad base ; the leaf-like bracts long-acuminate, gradually reduced 

 upwards to short -linear forms : inflorescence leafy-bracteate, 

 crowded, 10-15 cm. long, curved, ascending : cymes short-pedun- 

 cled, 3-7-flowered, symmetrically developed but appearing secund 

 by all the parts of the inflorescence being crowded over to the 

 outer or lower side of the prostrate-assurgent stems : sepals broadly 

 lanceolate or abruptly long-acuminate from a broad base, margins 

 scarious, moderately and irregularly serrate, somewhat shorter 

 than the corolla-tube proper : corolla moderately ventricose-am- 

 pliate, hardly bilabiate, sparsely white-bearded in the throat, about 

 3 cm. long, tube proper about one-third the total length, lobe- 

 rounded, spreading : sterile filament' flattened at apex, moderately 

 yellow, comose or even glabrous ; stamens from sparsely short- 

 hirsute to glabrous ; capsule firm-coriaceous, conical, two or three 

 times as long as the calyx. 



This plant has the general floral character of P. glabcr Pursh 

 and is certainly closely allied to it. It seems, however, that its 

 stout rootstock, the spreading prostrate habit of its numerous 

 stems, which are always puberulent, the oppositely secund flowers 

 and leaves mark it as specifically distinct. It is, possibly, some- 

 what local, occurring, so far as observation goes, only on river 

 banks, usually on the otherwise barren sandbars.

Emmenanthe scopulixa. 



Small, pubescent but scarcely glandular, cinereous-gree». 

 branched from the summit of a slender tap-root ; branches short, 

 ascending, two to several, 1-3 cm. long (often so short as to ap- 

 pear stemless): leaves ovate, elliptic or oblong in outline, fro" 

 crenately lobed to nearly entire, 5-12 mm. long, petioles usuaii} 

 exceeding the blade : flowers in short racemes (sometimes seem- 

 ingly solitary) from the axils of the leaves ; pedicels short, rare 

 exceeding the calyx in length : sepals linear, obtuse, less than
