E. Ritro L. (Plate XVIII). Plant 1-2 ft. high, usually branched but some- 

 times simple and i-headed, white tomentose, not glandular. Leaves pinnatifid, 

 green and glabrous or cottony above, white tomentose beneath, lobes very spiny. 

 Scales of partial involucre glabrous. Flowers blue, in a more or less spherical 

 head. Each floret has a separate involucre. 



Stony slopes and waste places. July-August. 



E. sphaerocephalus L. A taller plant, erect, glandular. Leaves pin- 

 natifid, cottony beneath. Scales of partial involucre glandular-hairy. Flowers 

 whitish or very pale blue, in a very spherical head. 



Uncultivated ground in the montane region, rather rare. June-September. 



ARCTIUM L. BURDOCK. 

 A. LappaL. = A. ma jus Bernh., A. minus Bernh., and A. tomentosum

X. inapertum Willd. An erect whitish annual with spreading branches. 

 Leaves sessile, linear, entire, white tomentose. Heads solitary, ovoid, many 

 flowered. Involucral bracts glabrous, mucronate, the outer broadly obovate and 

 almost transparent. Flowers purple. 



Dry places and stony fields. June-August.

 Lagoubran. The involucre is cylindrical, the involucral bracts are not mu- 

 cronate, and the outer ones are dorsally tomentose. 



Dry places. June-September.

S. dubia L. A much branched, leafy under-shrub. Leaves white tomentose 

 beneath, linear and almost entire, sometimes sinuate. The white pappus is much 

 longer than the cylindrical reddish-purple involucre. Flowers purplish. 



Arid stony places, fairly common. May-July.
