19° SUB-ALPINE PLANTS 



spikes are at first ovoid and then cylindrical. Stigmas 3. Stamens

Pastures on siliceous soil up to 8000 feet. July, August. 



Distrihulion. — Southern Germany, Southern Austria, Central and 

 Western Alps ; Pyrenees, Spain. 



Phyteuma spicatum L. (Plate IV.) 



Stems 1-2 feet high, rather stout, usually glabrous, leafy below. 

 Root-leaves longly petioled, ovate heart-shaped, crenate-dentate ;

 serrate ; upper stem-leaves narrower, sessile. Involucral bracts 

 lanceolate, somewhat serrate. Flowers deepest blue, or sometimes 

 deep blue-violet, in globular heads an inch in diameter. Stigmas 3. 

 Very variable in size. 



Meadows and pastures from the plains to about 8600 feet ; often 

 very abundant, especially on limestone soil from 4000-5000 feet. 

 June, July. 



Distribution. — Central and Southern Europe, extending to the 

 Chalk downs of Southern England. 



Phyteuma Halleri All. 



The tallest and stoutest species. Stem 2-3 feet high, thick, 

 hoUow, leafy at the top. Radical leaves with very long petioles, 

 broadly heart-shaped, and irregularly or coarsely toothed ; upper

 Flowers in panicles, racemes, or spikes, or rarely solitary, and
