Hieracium, Linn. 239. 



The Hieracia will be treated separately in detail in the Appendix. 

 Mr. Riddelsdell recognises 36 forms — species and varieties — as 

 occurring in Glamorgan. The exposures of grits on the coal measures, 

 coal tips, railway embankments, and slag hills, offer suitable habitats 

 for these plants, and they should be systematically studied and 

 collected. A good reference collection is being formed in the National 

 Museum of Wales. There is no middle course between accepting the 

 results of Linncsus — Species Plantarum, 1753 — and the modern 

 work of a specialist like the Rev. W. R. Linton. There can be little 

 doubt that the segregates recognised by Linton stand the test of 

 experimental culture. As hybrids are rare, the forms cannot very 

 well be due to the recombination of characters in the offspring of 

 these. I have grown two closely allied forms from seed for two 

 generations, and influenced by the results, suspect that most, if not 

 all, of the recognised varieties are distinct and constant types. 



For the present, the records furnished by correspondents may 

 be summed up as follows : —
