the scanty remains of the fruit of the former collection were analogous to that 

 of E. nanxim var. Terglovense, DC, well-formed fruit of the present collec- 

 tion is nearly as E. villosum is described and figured, having an Indexed mar- 

 gin with eiliate-spinulose teeth, thus lending confirmation to Dr. Hooker's 

 view. And the back is almost as concave as in an Omphalodtk. It will thus 

 apparently take the name of E. villosum var. aretioides. 441. Lithospermux 

 pilosum, Nutt. ; same as 295 of Parry. 442. Mhrtkxsia §7b?rica, Don., non 

 DC. Small form, exactly the Paltoonaria cttiata, Torr. Dr. Parry, as be- 

 fore (285), collected large forms, and now. some with the leaves more glau- 

 cescent beneath. 443. Mertensia alpixa, Don. Palmonarfa alpina, Torr. 

 Barely a span high. *~444. A very dwarf and hirsute form of the last, the sepals 

 strikingly ciliate with long hirsute hairs, from South Park. These two num- 

 bers, and additional still dwarfer specimens of Parry's No. 286, induce me 

 now to refer the latter (along with M. Drummandii) to M. alpina. 445 . M. 

 alpina, Don., var. ; the loosely paniculate, small-flowered form, Dr. Parry's 

 28 4, 'mixed in my set with M. Fendleri, Oray, Rev. Mertens., in fcfuppl. Enum. 

 PI. Parry, p. 46 (339) ; the latter, perhaps, runs into the former, but it is 

 readily known by the barely 5-cleft calyx ; the lobes only equalling or shorter 

 than the tube.

448. PoLEMONirM cJERrLECM, L. A very viscid-pubescent and glandular va-

 top,) Gejer's 530, and Fendlers 645. M Low and middle elevations.' 449. 

 P. ceruleum, L., answering to the plant of the Old World, except that Trie 

 seeds are more or less wing-margined at each end ; so it is the var. ? ptero-

 Hook. "High alpine, and at lower elevations." 452. P. pulghbllum,
