20 PLANTS BAKERIAN.E. 



differences in inflorescence, calyx and achene, preclude the 

 confusing of them. It is Mr. Bakers' n. 193. 1 



OREOCARYA HORRIDULA. Low inulticipitous perennial, 

 the not stout rather loosely leafy and floriferous steins 4 to 

 7 inches high, the whole plant strongly setose-hispid : obo 

 vate obtuse upper end of the leaf tapering spatulately to a 

 rather long and narrow petiolar base: racemose short 

 branches of the loose and short inflorescence linear-bracted, 

 but the bracts barely equalling the calyx; this in fruit J 

 inch long, its linear and narrow segments covered with 

 hispid hairs; corolla white, rather more than J inch long, 

 with narrow tube and small spreading limb: nutlets (only 

 one, usually) narrowly ovate, erect and straight, sharply 



1 The characters of two northwestern Mertensias may here be given : 

 M. SYMPHYTOIDES. Stout, erect, barely a foot high, leafy to the 

 summit and even throughout the broad cymose-panicled inflorescence 

 with large elliptic-lanceolate acute leaves, these of a bright green and 

 appearing glabrous, but sparsely somewhat tuberculate-scabrous, espec- 

 ially on the margin and the lower face : leafy cyme rather lax ; calyx 

 rather small, deeply cleft, the segments ovate- trigonous, acute, glabrous 

 except as to the margin, this very shortly and almost obscurely scabrous- 

 serrulate : corolla y 2 inch long, quite tubular,, the upper portion quite 

 cylindric and little shorter than the proper tube : nutlets rather coarsely 

 low-tuberculate. Known to me only from Emigrant Springs, in the lava 

 beds of Modoc Co., California, where it was collected by Mrs. R. M. 

 Austin, 20 June, 1894. 



M. STENOivOBA. Size of the preceding, quite as leafy, but the leaves 

 oblong-lanceolate, acute, thin and quite glaucous, sparsely scabrous, 

 most so marginally : inflorescence as in most species : calyx parted into 

 narrowly lanceolate- acuminate long segments, their margins sparsely 

 setose ciliolate : full grown nutlets scarcely half as long as the calyx 

 and sinuate-rugose. Based Mr. Flodman's n. 752 from the Bridger 

 Mountains, Montana (as to the specimens in my set), and named by Mr. 

 Rydberg "M. lanceolata, DC." But it can have no intimate connection 

 with Pursh's type on which the species was founded ; for that has a 

 " short calyx," while here that organ is rather extremely elongated.
