74. Hieracium (Archi-Hieracia) spp. [Lit. Brit . 23 ; 
N.C.E. 1 , 3 c, 11 , 16 , 18 , 33 , 34 , 35 , 40 ; De Vries 2460 ; Loew 
1358 ; Arct. 36 ; Alps 2 , 34 ; Pyren. 17 .] By the kindness 
of Mr. F. J. Hanbury and the Rev. E. F. Linton, who 
examined our specimens of Hieracia, we are able to give 
names to a number of forms. The Clova mountains are very 
rich in these, and some of them we have studied. The 
following notes give our observations ; we have found it 
impossible to do otherwise than lump the forms together 
in enumerating the insect visits. Recognizing in the many 
forms of Hieracia incipient species, we find our chief interest 
in noting any characters which would promote segregation 
of the group by preventing indiscriminate hybridisation or 
crossing. A tendency to flower early or late, a separation in 
habitat, or a more complete self-pollination than is usual
