Hab. Gravelly soils on the banUs of streams, common in the valley of the Columbia. Douglas. — " Three 

 to five feet high." Stem dai-k-purple above. In the only specimen in my possession the leaves are very 

 remote, gradually smaller upwards, the margins near the base with many rather stout spines. The outer 

 scales of the involucre are lax and patent, nearly equalling^ the innermost ones in length. 



7. C.foliostis; caule erecto simplici (?) robusto striate sublanato, foliis erectis superne 

 numerosis flores excedentibus lineari-lanceolatis moUibus irrcgulariter sinuato-dentatis 

 spinis rigidiusculis inequalibus ciliatis supra parce hirsutis subtus arachnoid oo-tomentosis

 squamis linearibus appressis, pappo copiosissimo. 



Had. Prairies of the Rocky Mountains. I)nimmond.—T\ii% is a very remarkable species, of which 

 unfortunately only two specimens exist in the collection. The stems are sinj^nlarly erect and straij,^ht, and 

 the leaves also erect, 6-S inches lono^, the uppermost very numerous, considerably exceeding, and almost 

 concealing', the flowers.

1. S.alpina; foliis lanceolatis dentatis subtus lanatis radicalibus ovato-lanceolatis petio- 

 latis, floribus corymbosis congestis, involucri superne villosi squamis oblongis. De Cand,— 

 Serratula alpina. Linn,— Engl. Bot. L 599.-/3. densa; caule subdecumbente, foliis glabrius-

Hab. /3. Elevated parts of the Rocky Mountiuns. Drummond.^y. North of the Saskatchawau to the 

 Bear Lake, in lat. 66° North. Dr. Richardson: and extending to Behring's Straits. C/mwisso.— Two (and 

 if as I suspect, the following species should be united with it, three,) very remarkable states of this plant are in 

 the collection, and aU exceedingly different from our British 5. alpina, which is more robust, and has much 

 broader and more woolly leaves.-Var. /3. has the stem decumbent, the leaves copious, crowded, and as long 

 and broad in the upper as in the lower portion of the stem.-Var. y. is very similar in habit to my 

 specimens from Mont Cenis, and from Norway, (in the Uuio Itineraria, 1828,) but the leaves are almost 

 entirely glabrous and more rigid,

 cylindracei villosi lanceolatis acutis. Rich, in FranM. Ut Joum. ed. 2. App. p. 29.— S.

 between the Mackenzie and Coppermine Elvers, (2</ J<>«n>0 -Dn/J.cAar*o«.-Onespec>men only ex.sts 

 in the collection of the 2d Expedition, and this quite agrees with the character given by Dr R.chardson of 

 his S. monticola. It has narrower, more rigid and entire leaves, and a more hairy involucre than S. alptm.
