680 Rydberg : Rocky Mountain flora 



This species has been variously named Cryptanthe Iciocarpa, 

 C. ambigua, and C. Torreyana. It differs from the first in the 

 2-forked groove, from the second in the smooth nutlets, and from 

 all in the large corolla. It is most related to C. Torreyana, 

 having somewhat similar nutlets, but is easily distinguished from 

 it by the large flowers and broad leaves. It may be the same as 

 the large-flowered form of C. Torreyana calycosa referred to by 

 Piper ; * but it does not have the elongated calyx-lobes of that 

 species and has three to four times as broad corolla.

Mertensia pallida sp. nov. 



Perennial, with a thick rootstock ; stem glabrous, very pale, 

 5-8 dm. high, leafy ; lower leaves oblanceolate, the upper narrowly 

 lanceolate, 5-8 cm. long, glabrous or minutely muriculate, ciliolate 

 on the margins, pale ; inflorescence narrowly paniculate ; pedicels 

 usually strigulose or sometimes the hairs represented only by the 

 somewhat pustulate bases ; calyx-lobes oblong, about 1 mm. long, 

 obtuse, ciliate on the margin ; corolla about 1 cm. long, the tube 

 about equaling the limb ; filaments about 1 mm. long, dilated and 

 at the apex broader than the anthers, which are about 2 mm. 

 long. 



This is related to Mertensia ciliata but differs in the paler nar- 

 rower leaves, the smaller corolla, and the usually strigulose 

 pedicels.
