666 ANGIOSPERMAE—DICOTYLEDONES 



disk-florets are 11-12 mm. long, and the bells 3^4 mm. deep. Warnstorf describes 

 the pollen-grains as resembling those of C. Jacea, but as much as 75 ju, long and 

 44 /A broad. Purely female stocks with vestigial stamens in the disk-florets were 

 observed by Ljungstrom in Sweden.

1574. C. nervosa Willd. (Herm. Muller, ' Alpenblumen,' pp. 415-16.) — The 

 red heads of this species are 60-70 mm. in diameter. There are about 20 neuter 

 ray-florets, modified into tubes 22 mm. long, with 5 lobes 15-20 mm. in length. 

 There are about 100 disk-florets, each with a corolla-tube 8-9 mm. and a bell 

 5 mm. long. The flower mechanism agrees in other respects with that of C. Cyanus. 



Visitors. — Herm. Muller observed 5 humble-bees and 14 Lepidoptera in the Alps.
