 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. (Chrysothamnus) 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. jffi5. L. (Chrysotiiamxus) viscidi- 

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

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

interesting rediscovery of a very rare plant. 



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

 streams. 



2 Off . Artemisia arctic a, Less. (A. Norvegica, Fries) ; a more hairy form, 

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

 Richankoniana. " Strictly alpine." 29, ^ A. scopulorum, n. sp.,J 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. Richard soniana. 300. A. Cana- 

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

 A^caudata and some forms of the next. 302. A. dracunoui.oides, Parah, var. 

 brevifolia, and specimens with trifid leaves passing into 301. 303, 205, (also 

 411 and 412 of Parry). A. Ludoviciana, a form with small leaves7*and also the 

 var. gnaphalioides. 304 . A. frigida, Willd. 306. A. tridentata, Nutt.§ 

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

 Torr. (308. See Chenopodiacese.) 



* No. 414 nf Parrrs separate collection is a glabrate form of the same common species, of which 

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