that the form ‘‘is, as far as I know, unrecorded in Britain. This is 
a plant which last year I had confounded with H. amphibolum, but it 
is easily distinguished from that plant by the more leafy rigidum- 
like stem, and the numerous longish set# on the involucre.” Mr. 
Ley refers to H. melanocephalum Lindeb. plants from Goathland, 
yv.-c. 62; Upper Teesdale, v.-c. 66; Aberdare, county 41; Defynog 
and Callwen, county 42. They differ widely in facies "from one 
another, but all show their near relationship to H. rigidum Hartm. 
The Aberdare and Defynog plants are queried by Mr. ad? some of 
those from Aberdare are sent for comparison.—H. J. RippetsDELL.
