H. S. Thompson. I think this is H. Desetangsii Lamotte. 
The generally acute sepals, the many translucent glands in 
the leaf, and the obsolescent or obsolete intermediate ridges 
on the stem all point to this. I have never seen the stem 
nearly so strongly angled (or ridged) as that figured in 
“ Butchpr and Strudwick,” plate 109. Salmon’s figure 
( Journ . Bot. 1913) gives a more correct representation, though 
the angles of the stem are not sufficiently indicated. — E. 
Drabble. Later : I still say that this is nearer to Desetangsii 
than to anything else. The sepals, especially in the buds, are 
broader and more obtuse than usual an the stem less strongly 
angled, though not less so than in Salmon’s plate. It is not 
dubium nor 'perforatum, and of course tetrapterum is out of the 
question. 1 cannot rule out a hybrid origin but am very 
loath to invoke hybridity without very strong evidence. — 
E. Drabble. 
Mr. W. R. Sherrin and I carefully examined this plant and 
came to the conclusion that it was probably H. perforatumx 
dubium, as it showed characters of both, but was clearly 
neither one nor the other. — E. C. Wallace. Mr. Fraser 
writes : — These plants have smaller leaves than my H. dubium 
from Kent, nor arc the stems so distinctly quadrangular. 
Some of the sepals are more or less acute. This variation 
does suggest hybridism, and the smaller leaves might suggest 
H. perforatum as the other parent, giving narrower leaves, 
more translucent glands (in some of the leaves) and some of 
the sepals acute. — E. C. Wallace. 
1 think from the scarcely quadrangular stem and the 
numerous pellucid dots of the upper leaves that this is H. 
dubium X perforatum. This hybrid, which 1 have raised 
artificially, formerly occurred on Wimbledon Common and 
probably appears frequently in nature. I suspect that H. 
Desetangsii Lamotte, whose characters are admittedly unstable, 
consists of forms of this cross. — H. W. Pugsley. 
Hypericum linariifolium Vahl. Near Dartmouth, S. Devon, 
1900. — Coll. E. J. Hanbury, Comm. J. W. White. This is 
the typical species, which grows also in Carnarvonshire. It 
differs considerably from var. approximatum Rouy, which 
occurs in Jersey. Vide Journ. Dot. liii, 162 (1915). — H. W. 
Pugsley. 
Hypericum elodes L. Whitmoor Common, Surrey Aug 7 
1930.— R. J. Burdon.
