 the two lateral ones ending in a solitary flower with naked ped-

 more solitary flowers in like manner. The corolla is 25 mm. 

 long, strongly bilabiate, with a densely bearded and purple dot-

This plant was first described by Greene in Bull. Cal. Acad. 

 1: no. 1S85, as M. TiliiigiRQgt\. Ten years later, in Journal 

 of Botany {V,\: 8, he ar.nounces that Kegel's plant is a member 

 of the Langsdorjfii group, and gave the name M. implcxus to 

 this plant. A year later he discovered that his implexus in- 

 cluded two distinct species, and in Erythea 4: 2, described M. 

 cora/liiiKs. We found this latter species in our implexus cover, 

 Heller joo^, collected July 23, 1903, three miles above Truckee, 

 Nevada county, California. The character of the rootstocks of 

 this species, well shown on the above mentioned specimen, are 

 extienieh- interesting and characteristic. 



Greene also calls attention to the character of the leaves of 

 J/. zV;^/>/^.iv/i', which he describes as "exceedingly thin membran- 

 aceous," and explains that this character belongs to AI. coralli- 

 nus and r.ot to implexus. 



Specimens were collected at the time the photogra|)h was 

 taken, and it is from these we get our notes. They are from Mt. 

 Rose, Washoe county, Nevada, elex-alion 9650 feet August 17, 

 1905, Kennedy iigo. Heller also collected it in a more reduced 

 form at the same place in September, 1909, no. ggdg. Another 

 sheet placed here is from the East Humboldt or Ruby mona- 

 tains, Elko county, August 11, 190S. elevation loioofeet, Hel- 

 ler gjS6. 



This species may be looked for in herbaria in that great 

 aggregate of forms and jierhaps species under the guise of M. 

 Langsdor^ii. So far as we know, it is not in cultivation, but it 

 would be difficult to find a plant more acceptable to lovers of 

 alpines.
