NATURAL SCIENCES OF PHILADELPHIA. 67 



309. Antennaria Carpatiiica, var. pulcherrima, Hook. A remarkable and 

 leafy-stemmed form.* 310. A. dioica, Gsertn., and A. alpina (female, 1-3- 

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

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

 Whippl., Exped. Pacif. R. R. Surv. 4, p. (54) 110; a less strict and many- 

 stemmed form. "Wet places in the mountains." 312. G. decurrens, Ives. 

 " Subalpine ; rare." 



313 (and 423 of Parry). Brickellia grandiflora, Nutt., var. minor : foliis 

 profundius cordatis capitulisque minoribus ; involucri squainis aeutioribus. 

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

 with. If. frigida. " Near Pike's Peak." 315. Liatris punctata, Hook. 



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

 fastigiatus and S. exaltatus, Nutt., but dwarf. "A common and variable 

 species, at all heights and in all situations, flowering from June to September." 

 32b*. A dwarf form of the same, nearly Parry's 21, and just Fendler's 477. 

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

 exaltatus, Nutt. 317. S. amplectens, Gray, Enum. PI. 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. S. integerrimus, Nutt. A low form; "alpine." 319. S. Solda- 

 nella, n. sp.J "High alpine, among rocks ; heads generally single." They 

 are solitary in all the specimens I have seen. 320. S. cernuus, Gray, Enum. 

 PL Parry, No. 52. " A common species at middle and subalpine elevations." 



321. S. Bigelowii, var. Hallii.\\ "Subalpine; heads very drooping, ray less." 



322. S. Fremontii, Torr. and Gr. " Alpine ;" a well-marked species. Recently 

 collected by Dr. Lyall on the summit of the Rocky Mountains, in lat. 49. ^ 



323. S. triangularis, Hook., with shorter and finer teeth to the leaves, the 



* Antennaria margaritacea, Pi. Br., var. sithalpina: caule spithamseo ad subpedalem simpli- 

 cissimo, corymbo congesto fere capitate A singular, nearly alpine form, collected only by Dr. 

 Parry, No. 421. 



f Senecio amplectens (Gray, 1. c.) : lana fioccosa mox decidua glabratus ; caule semi-sesquipedali 

 e radice perenni apice nudo 1-3-cephalo; foliis membranaceis oblongis lingulatisve aut repando 

 aut argutissime dentatis nunc sublaciniatis, imis basi ansrustatis vel in petiolum alatum attemiatis, 

 superioribus sessilibus basi (nunc lata) semiamplexicaulibus; capitulis in pedunculo gracili 

 nutantibus ; involucro calyculato Iaxo ; ligulis linearibus elongatis (1-2-pollicaribus) aureis; 

 acheniis glaberrimis. 



Var. taraxacoides (S. Fremontii, \a.r.1 Gray, PI. Parry, p. 9, No. 28): vere alpinus, 4-5-polli- 

 caris, monoeephalus ; capitulo minori minus nutante (ligulis semi-subpollicaribus) : foliis omnibus 

 basi attemiatis pi. m. laciniatis. In the high and bare alpine region. This, judging from interme- 

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

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



J Senecio Soldanei.la (sp. nov.) : subcaulescens, nanus, glaberrimus, subglaucus, fere semper 

 monoeephalus: radice fasciculato-fibrosa ; foliis crassis subtus purpureotinctis, radicalibus imisque 

 orbiculalis nunc subreniformibus nunc basi trinervata in petiolum longuni seu longissimum pla- 

 num contractis srepius denticulatis (circiter pollicem diametro), superioribus 1-2 minoribus 

 oblongis spathulatisve petiolo brevi dilatato ; capitulo magno (8-9 lin. lougo etlato); involucro e 

 squamis laneeolatis scarioso-margiuatis 1G-20 cum exterioribus 7-9 angustioribus immarginatis 

 laxioribus vel paullo vel dimidio brevioribus; ligulis oblongis 16-18 (flavis circiter 4 lin. longis) 

 discum vix superantibus ; acheniis glaberrimis. " On Gray's Peak," Br. Parry, who complimented 

 the describer by naming this handsome and most distinct species, S. Grayi; but the S. Grvji, 

 Hook., f. of New Zealand forbids this. 



(J In Middle Park, Br. Parry gathered one or two specimens of what appears to be S. hydro- 

 philus, Nutt. ' 



|i Senecio Bigelowii, (Gray in Bot. Whippl. Exped. Pacif. R. R. Surv. 4, p. (55) 111), var. HaMi: 

 foliis fere omnibus laneeolatis cum caule pilis articulatis pubescentibus (demum glabratis), caulinis 

 omnibus sessilibus imisve in petiolum alatum contractis. S. megacephalus, Nutt., thus far found 

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

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



% Senecio Fremontii, (Torr. & Gray, Fl. 2, p. 445) : totus glaber; caule simplici vel corymboso- 

 ramoso usque ad apicem folioso (5-15-pollicari); foliis oblongis vel obovatospathulatis carnosu- 

 lis plerisque Iaciniato-dentatis omnibus sessilibus, superioribus pollicaribus vel sesqui-pollicaribus, 

 inferioribus decrescentibus, capitulis solitariis paucisve brevissime pedunculatis erectis; involucro 

 campanulato (semipollieari) parce bracteato; ligulis 10-16 luteis; acheniis puberulis.
