 Gn. 61, p. 327. R.H.S. 39:104. The plant is recom- 

 mended to "be grown in turf to which has been added

 Ivs. fairly densely clothed with short discolored glands, 

 intensely rank-smelling, yellowish green, rather soft, 

 often more or less curved, the margin not at all carti-

 obtuse or acute, gradually narrowed or contracted to a 

 petiole more or less equaling the blade, dentate, wavy- 

 dentate or entire: scape glandular, exceeding the Ivs., 

 bearing a several- to many-fld. umbel: bracts broad- 

 ovate: fls. 1-sided, nodding, fragrant, violet or red- 

 violet; calyx glandular, or even sparingly farinose, 

 narrowly campanulate, split to the middle with the 

 lobes acute or subacute; corolla-tube gradually broad- 

 ened from the cylindrical base, the throat sparingly 

 farinose, the limb funnelform almost J^in. across with 

 emarginate lobes : caps, more or less exceeding the calyx. 

 Mountains of S. Eu., in several forms. Gn. 61, p. 430; 

 69, p. 186; 73: 572. G.W. -15, p. 272. H.F. 1:242.

 Ivs. smaller and oval or oblong, entire or only lightly 

 toothed: umbel many-fld. R.H.S. 39:104. The P. 

 viscosa of commerce, according to Mac Watt, is chiefly 

 varieties of P. hirsuta. 



DDDD. Bracts broad and leafy: fls. bluish violet 



54. glutinosa, Wulf . Deciduous: 3-4 in.: Ivs. glandu- 

 lar-viscid, rather stiff, somewhat shining, punctate 

 above, the margin toward the apex subcartilaginous, 

 lanceolate-cuneate or oblong-lanceolate, gradually nar- 

 rowed to the short-petiole, obtuse, denticulate from 

 the middle, rarely subentire : scape exceeding the Ivs., 

 bearing a little head of 1-6 fls. : bracts broad, imbricate, 

 frequently brownish purple, broadly ovate, obtuse: fls. 

 fragrant, intense blue finally violet, rarely white; calyx 

 glandular, not split to the middle, with ovate obtuse 

 lobes; corolla-limb Yt-% in. across, funnelform, with 

 divaricate bifid lobes: caps, slightly shorter than the
