Rydberg : Rocky Mountain flora <i41 



Colorado: New Windsor, 1894, Ostcrhout (type); McCoy, 

 1898, Shear & Bessey SJ02 ; Colorado Springs, 1896, Shear 5189. 



Monardella dentata sp. nov. 



Cespitose perennial, somewhat ligneous at the base ; stems 

 slender, light brown, about 3 dm. high ; leaves short-petioled ; 

 blades ovate, 1.5-2 cm. long, serrate-dentate, finely pubescent and 

 strongly punctate, obtuse, strongly veined beneath ; heads ter- 

 minal, solitary, about 1.5 cm. in diameter; bracts lanceolate, 

 obtuse, nearly 1 cm. long, finely canescent, strongly veined, 

 rather thick, of fully as firm structure as the upper leaves ; calyx 

 about 8 mm. long, grayish pubescent ; lobes lanceolate ; corolla 

 about 12 mm. long; its lobes linear, 4 mm. long. 



This has been mistaken for M. odoratissima, but is easily dis- 

 tinguished by the distinctly toothed leaves and the narrow firm 

 bracts. 



Colorado: Gray's Peak, 1872, Torrey. 



Solanum interius sp. nov. 



Annual, more or less branched ; stem 3-6 dm. high, usually 

 with narrow denticulate margins or wings, finely pubescent with 

 short white appressed crisp hairs ; leaves with short winged peti- 

 oles, sparingly pubescent above, usually densely grayish-strigose 

 beneath ; blades deltoid or rhombic, i~j cm. long, acuminate, 

 usually sinuately lobed or dentate with acute or acuminate lobes 

 or teeth ; peduncles 2-4 cm. long, strigose ; inflorescence corymbi- 

 form, rarely umbelliform ; pedicels in fruit about 1 cm. long, 

 recurved but scarcely reflexed ; calyx-lobes ovate, 2 mm. long, 

 abruptly acute, in fruit appressed or spreading ; corolla yellowish- 

 white ; lobes ovate, acute, 3-4 mm. long; filaments very short, 

 less than 0.5 mm. long, glabrous; anthers oblong, about 2 mm. 

 long, yellow, obtuse, opening by terminal pores ; berry greenish 

 black, nearly I cm. in diameter. 



This has gone under the name of S. nigrum throughout the 

 interior region where it is a native plant ; but the true 6". nigrum 

 of Europe has almost glabrous leaves with rounded lobes if lobed 

 at all, very obtuse sepals, subumbellate inflorescence and usually 

 reflexe.d pedicels in fruit. 5. interius is in reality more closely 

 related to 5. Douglasii, which, however, differs in the much larger 

 and bluish corolla. It is with some doubt I propose this species 

 as new, as several North American species were described by
