or pinnatifid nearly glabrous, stalk branched scaly and thickened 

 upwards, inv. glabrous or hairy. E. B. 830. Leontodon Koch. 

 L. all radical, tapering at the base, often with long linear 

 spreading segments, usually somewhat hairy particularly on the 

 midrib beneath. Inv. nearly always hairy. Pappus brownish. 

 j3. A. Taraxaci (Sm. not Willd.}\ 1. glabrous, stalk mostly simple, 

 inv. shaggy with greenish-black hairs. E. B. 1109. y. sordida; 

 1. hairy, st. branched, inv. as in /3, plant very large. Meadows 

 and pastures. /3. mountains, y. Highland glens. P. VIII. 



38. TRAGOPOGON Linn. Goafs-beard. 



1 . T. minor (Fries) ; inv. about twice as long as the florets, 

 ped. slightly thickened at the very summit, 1. tapering into a long 

 slender point from a dilated base. T. major Hook, (not Jacq.) 

 St. 2 feet high, branched, erect. L. clasping the stem, gradu- 

 ally tapering into a very long acute point. Phyll. 8, in 2 rows. 

 Fl. yellow, truncate, 5 -toothed. Anth. dark brown. Marginal 

 fr. angular, striated ; angles squamosely toothed ; interstices 

 tubercular. Meadows and pastures. B. ? VI. VII. E. S. 



2. T. pratensis (L.) ; inv. equalling or shorter than the florets, 

 ped. slightly thickened at the very summit, 1. linear keeled dilated 

 at the base. E. B. 434. St. H 2 feet high, branched, erect. 

 L. clasping the stem, narrowing upwards and terminating in a 

 very long linear-acute point. Phyll. 8, in 2 rows. Fl. yellow, 

 truncate, 5-toothed. Anth. yellow. There are 2 forms of this 

 plant : (a) inv. equalling the fl., marginal fr. obsoletely striated 

 and squamosely-scabrous throughout; (6) inv. rather shorter than 

 the fl., marginal fr. (in my specimen) yellow slightly furrowed 

 and quite smooth. Meadows and pastures, less frequent than 

 the preceding. B. ? VI. 



f3. T. porrifolius (L.) ; inv. longer than the florets, ped. much 

 thickened upwards, 1. tapering slightly dilated just above the base. 

 E. B. 638. St. 34 feet high, erect, branched. L. slightly 

 broader just above the base then gradually narrowing to an acute 

 point. Heads twice as large as in the two preceding. Inv. 

 usually longer than the fl., sometimes only equalling them. Fl. 

 purple. Marginal fr. squamosely -tubercular throughout but par- 

 ticularly on the ribs. T. major is probably only a yellow-flowered 

 variety of this ; it has not been found in Britain. Moist mea- 

 dows. B. VI. Salsify. 



39. PICRIS Linn. 



1. P. hieracioides (L.); rough with forked and hooked bristles, 

 1. linear or lanceolate dentate or sinuated, upper 1. somewhat 

 clasping, heads solitary terminating the stem and branches, outer
