310 Key to the System of 



1405. Leaves deeply cleft into narrow lobes. 



Dwarf, often somewhat beset with minute jointed glandule- 

 bearing hairlets ; leaves acutely lobed or some lobeless ; 

 headlets of flowers small, on very thin and proportionately 

 long stalks ; involucral bracts comparatively few, blunt ; 

 fruits quite small, brownish, narrow, quadrangular, some- 

 what compressed ; pappus stellular. B. exilis. 



Leaves shortly cleft into broadish lobes. 



Dwarf, often beset with jointed hairlets ; lower leaves 

 pinnatifid, upper indented or some of them entire ; head- 

 lets of flowers rather small ; floral ray quite short ; fruits 

 angular, granular-rough, the marginal fruits ciliolated ; 

 pappus stellular. B. goniocarpa. 



Z.AGBNOPKORA. 



1406. Root producing elongated offshoots. 



Rather dwarf ; stems unbranched, slender ; leaves nearly 

 all basal, from obovate- to cuneate-elliptical, somewhat 

 indented or distantly denticulated, usually beset with, 

 short hairlets ; the stem-leaves mostly rudimentary and 

 bract-like; headlets of flowers quite small, singly terminal; 

 involucral bracts mostly narrow, in few rows ; expansion 

 of marginal corollas generally bluish ; perfect fruits com- 

 pressed, narrowed into a very short stalklet. 



L. BiUardieri. 



Root without any conspicuous offshoots. 



Somewhat tall ; leaves mostly basal, from lanceolar- to 

 obovate-elliptical, much indented, beset with jointed 

 hairlets ; stem-leaves quite small, entire ; headlets of 

 flowers singly terminal ; involucral bracts rather broad, 

 in several rows ; expansion of marginal corollas generally 

 bluish ; perfect fruits compressed, oblique-obovate, their 

 basal attenuation very short. L. Huegelii. 



SOIiENOGYNE 



1407. Stems robust, about as long as the leaves or shorter. 



Dwarf, often densely beset with minute hairlets ; steins 

 leafless, upwards slightly turgid; leaves radiate-spreading, 

 elliptic-cuneate ; headlets of flowers quite small ; in- 

 volucral bracts broadish, blunt ; marginal flowers very 

 small ; fruits considerably compressed. Figure 78.
