66 PROCEEDINGS OP THE ACADEMY OF 



Douglasii, ( C. Douglasii, Hook, and Am.) 352. Palafoxia Hookeriana, Torr. 

 and Gray, with smaller heads. 



285. Mach.ekanthera tanacetifolia, Nees, (Dieteria coronopifnlia, Nutt.) 

 286. Grindelia squarrosa, Dunal, with larger and with smaller heads. 287. 

 (and 425 of Parry,) Aplopappcs rpbiginosus, Torr. and Gr. 288. A. spixuloscs, 



DC. 289. ToWNSENDIA GRANDIFLORA, Nutt. 290. T. SERICEA, Hook. 



291. Aster (Oxytripolium) angustcs, Torr. and Gr. ( Tripolium angustum and 

 T. frondosum, Nutt.) 292. Linosyris (Chrysothamnus) graveolens, Torr. and 

 Gr. ; the form with small heads, and acute and viscid scales of the involucre. 

 It occurs, much better developed, in Parry's separate collection, No. 415.* 



293 (and 413 of Parry,) L. (Chrysothamnds) Parryi, n. sp.f A very distinct 

 species, which is said to abound in the Middle Park, South Park, and all 

 that district; the wonder is that it has not been detected before. The spici- 

 form or racemose and leafy inflorescence, and the large heads with lax and 

 taper-pointed scales, are characteristic. 295. L. (Chrysotkamnus) viscidi- 

 flora, Torr. and Gr. ; the variety with broadish and hispidnlous-ciliate leaves 

 (L. serrulata, Torr.) ; again collected also by Dr. Parry, under his number 49. 



294 (and 426 of Parry,) Guttierezia Euthamije, Torr. & Gr. 296. Macronema 

 discoidea, Nutt. " Blue River, west of the Rocky Mountain range." An 

 interesting rediscovery of a very rare plant. 



297. Pectis (Pectidopsis, DC) akgustifolia, Torr. Gravelly banks of 

 streams. 



298. Artemisia arctica, Less. (A. Norvegica, Fries) ; a more hairy form, 

 the same as Parry's 42, which I wrongly considered as a variety of A. 

 Richardsoniana. " Strictly alpine." 299. A. scopulorum, n. sp.,t a " strictly 

 alpine" species, allied to A. lanata, and to be compared with A. heterophylla, 

 Bess., which, however, is placed in the section Abrotanum, while this plant has 

 the woolly hairs of the receptacle as long as the flowers themselves, in which 

 respect it also differs from the very similar A. Richardsoniana. 300. A. Cana- 

 densis, Michx. 301. A glabrous form of the last, with small heads, too near 

 A. caudata and some forms of the next. 302. A. dracunculoides, Pursh, var. 

 brevifolia, and specimens with trifid leaves passing into 301. 303, 305, (also 

 411 and 412 of Parry). A. Ludoviciana, a form with small leaves, and also the 

 var. gnaphalioides. 304. A. frigida, Willd. 306. A. tridextata, Nutt. 

 " On the Blue River, west of the Rocky Mountain range." 307. A. filifolia, 

 Torr. (308. See Chenopodiaceae.) 



* No. 414 of Parry's separate collection is a glabrate form of tbe same common species, of which 

 only traces of the close and white down remain, and the leaves and heads are larger. 



t Linosyris (Chmsothamnus) ;Parryi (sp. nov.): fruticosa; ramis virgatis lanoso-dealbatis ; 

 foliis linearibus fere glabris BUbvisccsis, floralibus conterniibus capitula in tbyrsum angustum 

 congesta longe superantibus ; invi.lucro 10-15-floro cylindraceo panciscriali, squamis sublaxe 

 imbricatis albidis lanceolatis, omnibus (exterioribus ssepius folioso- interioribus scarioso-) attenuato- 

 acuminatis ; cordis tubo hirsutulo; acheniis linearibus cano-pubeseentibus. Leaves 2 to 3 

 inches long, 3-nerved, acute, plane, the larger ones 2 lines wide and tapering to the base. Thyrsus 

 narrow, often almost simply racemose or spiciform, sometimes more compound and branchy. Heads 

 about two-thirds of an inch long, foliose-bracteate; the bracts passing into the exterior and leafy- 

 tipped scales of the involucre. Receptacle, styles, viscidity, aroma, Ac, as in Chrysothamnus 

 generally. 



% Also No. 41 of Dr. Parry's separate collection of 1S62 (not of 1S61. which is A. borealis, a very 

 different species.) 



Artemisia (Absinthium) scopulorum (sp. nov.): casspitosa: rhizomate repente: caulibus sim- 

 plicissimis spithameeis: foliis albido-sericeis plerisque pinnati-3-5-sectis, eegmentis prajsertim 

 radicalinm tiipartitis, lobis cum foliis summis linearibus angustis; capitulis pluribus vel paucis 

 simplieiter racemoso-spicatis breviter pedicellatis erectis (lin. 2-3 latis), involucro hemisphserico. 

 squamis ovalibus extus dorso villosis margine lato scarioso atro-fusco cinctis; lana receptaculi 

 copiosa conllas superne longe pilosas adasquante. Var. monocephala ; caule 2-3-pollicari capitulo 

 Bolitario majori terminato; foliis etiam radicalibus simplieiter tripartitis vel partim 5-partitis par- 

 tim integerrimis linearibus. Stems sericeous-pubescent, sometimes glabrate below. Floral leaves 

 or bracts filiform, linear, entire, the lower surpassing the head. Pedicels a line or a line and a 

 half long, strictly erect. Flowers 30 or more, tipped with purplish. 



\ This is 410 of Tarry's separate collection, from Middle Park; and his 409, associated with th 

 above, is A. cana, Pursh ; these two being the Wild Sage of Lewis and Clarke.
