Frequent about Swansea and on the shores of this County. B.G. 

 In 1802, it was plentiiul on the sand-hills between Swansea and the 

 Mumbles, but has now become rare. It grows also sparingly on 

 the sea-side, between the Eastern Pier and the Crymlyn Burrows.

 p. 105. There appear to be no recent records for this plant. 



78. incana, R.Br. Hoary Stock. 

 Rare. Scarce. Native. Littoral. 



This plant apparently occurs on one almost inaccessible cliff on 

 the coast of Glamorgan, to the east of Southerndown, and is therefore 

 not to be confused with the plants recorded from the neighbourhood 

 of Swansea in the preceding note. The locality has been known to 

 the Rev. W. F. Evans, The School, Cowbridge, for some time. The 

 plants were shewn to me in 1900 or 1901 by my pupil, Mr. I. Buller 

 Pole- Evans, and two specimens were obtained with difficulty. These 

 and their offspring flourished in my garden at Penarth for three 

 seasons, and then were lost through the seedling plants being eaten 

 up by slugs. The plants resembled the Brompton stocks of our 

 gardens very closely, and changed colour under cultivation in the 

 second or third generation, perhaps as the result of crossing. They 

 were not at all like examples of M. sinuata collected on the opposite 

 coast of Devonshire. There were perhaps a hundred plants in flower 

 in the original locality on April i6th, 1906, all inaccessible except to 

 an expert cragsman provided with ropes. The colour was of a 

 uniform reddish purple, without any of that variability observed in 

 the specimens raised in my garden.
