5. Bauhini, Schult. Long barren run-

 LTpper face of L. covered with strong 

 hairs. Stem nearly smooth. 



^- piloselloides, Walle. As the last, except 

 that the stem is covered with a stellate

 and e. G. 



j8. setigerum, Tausch. Bristles spreading. 



y. cinereum, Tausch. Fl. fewer and much 



smaller. 



B. Deepanoide^. 



The want of bristles on the obtuse phyUa- 

 ries, and the divaricate branching of the stems, 

 separate these from the Pilosello' ; besides 

 which, excepting in E. saxatile, they have no 

 stellate pubescence on the L. The first cha- 

 racter will also go far to separate them from 

 aU the other divisions retaining theii' root-L. 

 Stalks scaly near the flower, and phyUaries 

 tiled in many series. 



i. Root creeping. Stem nearly naked. 



17. staticifolium. Stem 1-5-flowered. 

 Stalks long, thickened upwards : these and the 

 Cal. mealy. L. linear, somewhat obtuse, haii'- 

 less. p. 6, 7. Gravel of torrents. Alps. 



ii. Root not creeping. Stem leafy at hase. 



18. porrifolium. Stem 10-30 -flowered, 

 branched from base. Branches slender, usually 

 2-flowered. L. lineari-lanceolate, acuminate, 

 hairless or ciliate at base. Cal. and Stalks 

 hoary with stellate pubescence. Outer Phyll. 

 squarrose. p. 7, 8. Rocky mountains, s. e. G. 



19. grammifolium. " Hairless, glaucous. 

 Stem branched, leafy. Branches long, straight, 

 erect, scaly at top. L. linear, quite entire,

21. saKatile of Jacq. Obs. "L. mem-

 Root-L. ciUate at base. Cal. naked. Stalks 

 scaly, p. Cale. rocks. Baden in Austria. 

 Aargau." — DC. Koch, in his last ed., joins 

 this to porrifolium, yVoM which it differs by its 

 much broader L., covered beneath vnth a stel- 

 late pubescence. 



C. VlLLOS^. 



The long haii-s of the Cal. separate these 

 ft-om the last division. From the Pillosella, 

 which are much more different in habit, it is 

 more diflScult to fix upon a distinguishing 

 mark, when the plant, as is sometimes the 

 case, offers only one or two flowers.
