feathery fruiting heads are both conspicuous and beautiful. 
Shelbyville probably is the only station in North America 
where T. major is known to occur; its involucral bracts are 
about 3 em long at time of flowering and 6 at full maturity of 
the fruiting head.

Nyman FI. Euro. (1878-1882) 433. This variety differs from 
the species only in not being glandular. In‘a preceding paper 
I united it with var. glabrescens Gunth., Grab. and Wimm. ; 
but at that time I hadn’t seen any living plants of it. The 
flower heads are 3.5 to 5 cm wide, flowers orange, achene lin- 
ear, about 2.5 mm long, involucre 13-20 mm high. Imlay City, 
No. 668414, August 15; Wiard, No. 6813, September 19; 
Geddes, No. 6790, September 12, 1923. 
The var. glabrescens has a smaller head, not over 3.5 cm 
wide, flowers lemon yellow, seeds elliptic, about 1.75 mm. long, 
involucre smaller, not over 12 mm high. 
The typical, glandular form of the species is quite common 
and widely distributed in southeastern Michigan. 
Hieracium Florentinum, All. This species, commonly called 
King Devil, covers the sandy or gravelly hillsides near Lake 
Linden in great profusion. No. 6590, June 25, 1923. It has 
also spread into rich muck lands of drained swamps near Calu- 
met where it is of gigantic size, 10-15 dm. high; No. 6598b, 
June 21, 1923. |
