Rydberg : Rocky Mountain flora G85 



Hedeoma longiflora sp. nov. 



Perennial, with a slender taproot ; stems branched at the base, 

 decumbent or ascending, finely puberulent ; leaves spreading, linear- 

 lanceolate, lanceolate or oblong, 1-2 cm. long, grayish-puberulent, 

 subsessile ; calyx 7—8 mm. long, strongly ribbed, puberulent, some- 

 what saccate below ; teeth subulate, the lower 2 mm., the upper 1 

 mm. long; corolla about 12 mm. long, puberulent, with an ample 

 limb. 



This has been confused with Hedeoma Drummondii, but differs 

 in the broader leaves, which are divergent, and in the calyx, which 

 is distinctly saccate. H. Drummondii differs from the related 

 species in the narrow, ascending or suberect leaves and the narrow 

 calyx, scarcely at all saccate. H. longiflora has the long corolla of 

 H Drummondii and is distinguished thereby from H. sauc/a, H. 

 thymoides, and H. ovata, which have all been included in H. Drum- 

 mondii. It grows on cliffs and in canons of the Great Plains 

 region.

Madronella sessilifolia sp. nov. 



Perennial, with a short caudex ; stems stout, about 3 dm. 

 high, finely puberulent, densely so above ; leaves sessile or nearly 

 so, ovate or lanceolate, entire, obtuse, rather pale, finely puberu- 

 lent or in age glabrous ; bracts oval, ro— 12 mm. long, puberulent 

 on the back, ciliate on the margins ; calyx 8-9 mm. long, pilose, 

 striate; lobes lanceolate, about I mm. long; corolla 12-13 mm - 

 long, pubescent. 



The type was determined as Monardella odoratissima, but it 

 differs from that species in the pale foliage, the shorter and finer 

 pubescence, the broader leaves, and the less distinctly ciliate calyx- 

 lobes.
