the secondary veins obscure or indiscernible : flowers few, in a terminal 

 crowded cluster: calyx puberulent, its tube deep-red, 12-16 mm. long, 

 cylindric, with slightly dilated base and throat, lobes half as long, green 

 ish, triangular-lanceolate, callous tipped : petals thick, deep-red, obovate- 

 cordate, slightly exceeding the calyx-lobes : stamens barely exserted ; pol 

 len grains unusually large : stigma tardily well exserted: ovary and cap 

 sule minutely glandular-pubescent on the angles. 



This species belongs in the Z. latifolia group but can scarcely be con 

 fused with the typical Californian form of that species. 



Secured by A. O. Garrett, August 28, 1906, in Big Cottonwood Canon, 

 Salt Lake County, Utah ; type No. 2031. 



Mertensia micrantha sp. nov. 



Stems clustered, spreading, 2-3 dm. long, rather slender, glabrous or nearly 

 so: leaves dark green and seemingly glabrous but under a lens minutely 

 appressed-hispid on both sides, not pustulate, 3-7 cm. long; the uppermost 

 lanceolate, more narrowly so downward where they become smaller and 

 linear : panicle leafy, many-flowered ; flowers small ; calyx about 3 mm. 

 long, its lobes linear-lanceolate, ciliate-margined, longer than the cam- 

 panulate tube ; corolla about 10 mm. long, its limb as long as the tube, 

 narrowly campanulate, with short suborbicular lobes : the stamens in 

 serted in the throat and reaching to the lobes ; the filaments as broad or 

 broader than the anthers and nearly as long: style equalling the stamens. 



This seems to be a good species in the Lanceolatae and not very nearly 

 allied to any of the described species. 



It was secured by Dr. Francis Ramaley and Mr. W. W. Bobbins, on 

 Sugar-loaf Mountain, July 14, 1906. Type No. 1750. 



Douglasia Johnston! sp. nov. 



A depressed perennial, the caudex with few, slender, naked branches 

 not rising above the soil, each branch terminating in a close rosulate 

 cluster of leaves less than 1 cm. high and broad : leaves minute, 3-6 mm. 

 long, closely imbricated, glabrous except for a sparse marginal fringe of 

 white ciliae, mostly oblong, subacute, somewhat keeled : peduncles rising 

 singly from the center of each rosula, sparsely ciliate-hirsute as is also the 

 inflorescence : 8-10 mm. long : umbel crowded, few-flowered (3-8) : bracts 

 lance-linear, as long as the pedicel and calyx : pedicels nearly equal, very 

 short : calyx campanulate, its lobes lanceolate, subacute, as long as the 

 tube: corolla-lobes oblong obovate, as long as the tube, reflexed and 

 withering-persistent over the distended tube : stamens inserted just above 

 the middle of the tube, the large anthers extending to the narrowed ori 

 fice of the throat : capsule sessile, globose. 



This well marked species I believe is the first Douglasia reported from 

 Colorado. It was secured by Mr. Earl Lynd Johnston, August 16, 1906, 

 near the foot of Mt. Washington, on the trail to Chasm Lake, Long's 

 Peak. It bears the No. 339.
