ASPERIFOLI^E. 19 



MERTENSIA CYNOGLOSSOIDES. Stems depressed, 1 feet 

 long, sparsely and very amply leafy, the herbage delicate 

 in texture and of a vivid green: lowest leaves oblong, 

 obtuse, 4 or 5 inches long, on slender petioles of equal 

 length, the cauline ovate-lanceolate, acutish, sessile by a 

 subcordate-clasping base, these also 3 or 4 inches long and 

 spreading, all very thin, glabrous beneath, sparsely but 

 strongly scabrous above and scabrous-ciliolate: racemes few 

 and sparse, long-peduncled, the upper part of the peduncle 

 and the pedicels sparsely setose-hispid: sepals small, lanceo- 

 late and ovate-lanceolate, obtusish, hispid-ciliolate, other- 

 wise glabrous: corolla light-blue, almost funnelform, the 

 short and rather broad tube quite exceeded in length by 

 the campanulate limb into which it gradually passes: nut- 

 lets white (perhaps immature), ovate, incurved at summit, 

 turgidly and very irregularly rugose. 



On moist ledges in the Black Canon, 20 June, n. 191. A 

 remarkably distinct species. 



MERTENSIA MURICULATA. Of the size of the last, nearly, 

 and like it almost prostrate, but of firm texture and glau- 

 cescent: lowest leaves elliptical, the blade 3 or 4 inches long, 

 the petiole shorter; cauline ovate and lance-ovate, 1 to 2| 

 inches long, sessile and partly clasping, all finely dotted 

 above with white pustules developing centrally a low, stout 

 white scabrous point, the margin scabrous-ciliolate with 

 short pustulate hairs: flower-clusters in all the leaf-axils, 

 long-peduncled, somewhat crowded, not obviously racemose: 

 sepals very short, deltoid-ovate to shortly triangular-lanceo- 

 late, obtuse, setulose on the back and strongly hispid-ciliate: 

 corolla short and funnelform: nutlets ovate, straight and 

 erect, lightly rugulose and minutely tuberculate. 



Habitat of the last, and manifestly allied to it, though its 

 firm texture, peculiar pustulate roughness, as well as the
