to the Rocky Mountains. 225 



Hab. Crevices of rocks along streams, within the Rocky 

 Mountains. 



Obs. Allied to P. paniculata. This and the preceding 

 species should perhaps be referred to the genus Lithospermum, 

 as now characterised by Lehmann. 



292. Lithospermum incisum, Lehm. asperif. ii. p. 303. 

 Batschia longiflora, Purshji. i. p. 132. Nutt.gen. i. p. 114. 

 Valley of the Loup Fork. 



293. L. canescens, Lehm. 1. c. Batschia canescens, 

 Michx.f. i. p. 130. t. 14. 



294. L. decumbens, strigoso-hispidum ; foliis oblongo-li- 

 nearibus; calycis laciniis linearibus, tubo corolla? paulo bre- 

 vioribus ; corolla? lobis ovatis integerrimis. 



Batschia decumbens, Nutt. gen. i. p. 114? 



Obs. Plant very hispid ; flowers in a terminal fastigiate 

 fascicle. I have great hesitation in adding the above syno- 

 nym of Nuttall. 



295. L. angustifolium, Michx. jl. i p. 130. About 

 Council Bluff on the Missouri. 



Obs. Plant 8-10 inches high, slender, with a few erect 

 branches, strigosely hirsute ; flowers minute ; seeds turgidly 

 ovate, smooth and polished. It diners from Michaux's plant 

 in some respects, and is perhaps a distinct species. Mr. Nut- 

 tall found it on the Arkansa. 



296. Myosotis scorpioides, L. Willd. sp. pi. i. p. 

 746. Along the Platte. 



297. M. nana, Villars. Tor. ann. lye. i. p. 33. Rocky 

 Mountains. On comparison, this plant appears to be identical 

 with the European species. 



298. M. suffruticosa, caule suflruticoso, ramosissimo, 

 hirsuto ; foliis lineari-lanceolatis, hispido-pilosis ; spicis ter- 

 minalibus, pluribus ; floribus pedicellatis ; calycibus clausis, 

 seminibus laevibus, depressis. 



Desc. Root thick, ligneous. Stem, about a span high, shrubby below, 

 much branched, pubescent and hirsute. Leaves an inch long, and 2 lines
