leaTy^stemmed form.* 310, A. dioica, Gaertn., and A. alpina (female, 1-3- 

 cephalous), mixed. GooTspecimens of A. alpina were separately collected on 

 Mount Flora by Dr. Parry, No. 422. 311. Gnaphalium < irictum, Gray in Bot. 

 Whippl., Exped. Pacif. R. R. Surv. 47p. (54) 110; a less strict and many-

313 (and 423 of Parry). Brickeli.ia grandiflora, Nutt. v var. minor : foliis 

 priffundius cordatis capitulisque mfnoribus ; involucri squamis acutioribus. 

 314. Nakdosmia sagittata, Hook., var. with very obtuse leaves, connecting 

 wTtli N. frigida. " Near Pike's Peak." 315. Liatris punci at a, Hook. 



316. Senecio lugens, Richards., a typical form, and others belonging to 5. 

 fast'ujiatus and S. exaltatu*, Nutt., but dwarf. "A common and variable

 326. A dwarf form of the same, nearly Parry's 21, and just Fendler's 477. 

 325. S. lugexs, the downy state, same as Parry's 23, one of the forms of S. 

 exaltatas, Nutt. 317. S. amplectens, Gray, Enum. PL Parry, p. 11, No. 56, 

 a species which, considering the various forms under which it now occurs, was 

 not very well named. A new specific character is appended.! It is a sub- 

 alpine and alpine species. 



318. 8. integerrimus, Nutt. A low form ; " alpine." 310. S. Solda-

 diate forms in Hall and Harbour's collection, must be regarded as a depauperate alpine variety or 

 8. amplectens. Dr. Parry gathered only two or three specimens, like those of the former year.

 the de- -er by naming this handsome and most distinct species, S. Grayi; but tne a. urcyi, 



Ilnok., f<f New Zealand forbids this. - -_. * . P ,„^ 



3 In Middle Park, Dr. Parry gathered one or two specimens of what appears to do a. nyaro* 



P iVenewo Bigelowii, (Gray in Bot. Whippl. Exped. Pacif. R. R. Surv. 4, p. (55) 111), var. Hallii: 

 foliis fere omnibus laneeolatis cum caule pilis articular pubeacentibus (demum glabratis), caulima 

 omnibus s< ilibus imisve in petiolum alatum contractis. S. megacephalus, rsutt., tnus tar round 

 only by Nuttall, has a similar pubescence, but more of it, and alao on the involucre ; the scales 

 of the latter are narrower, the heads are radiate and erect, and the plant is dwarf. 



f Senecio Fremoxtii, (Torr. & Gray, Fl. % p. 445) : totus glaber; caule simphci vel corymboso- 

 ramoso usque ad apkem folioso (5-15-pollirari) ; foliis oblongis vel obovato-spathulatis carnosu-
