564 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Epilobium collinum^ Gmel. Orig. Argentiere, Switzerland. 
Hort. Reigate, July 3, 1910. — C. E. Salmon. Much enlarged by 
cultivation ; and thus looking a great deal nearer to E. monianum 
than the wild plant, as I have seen it in the Alps. Mr. J. F. 
Pickard lately sent me for examination some rather poorly de- 
veloped specimens from Nant Francon, v.-c. 49 Carnarvon, which 
may belong here ; I could not come to a definite conclusion from 
the material received, but it should be searched for in that district. 
— Edward S. Marshall. 
Epilobiu 7 H rosami, Schreb., var. (See Report, 1907, p. 251.) 
I send a few specimens of an Epilobhwi^ to show the descendants 
in the third generation of an interesting plant I sent the Club 
in 1907. This plant was regarded by Mr. Marshall as perhaps 
a cross between E. roseum and E. lanceolatwti ; but the curious 
fact remains, that no tjipical E. lanceolatum has ever been known 
to grow near the place. The commonest willow-herb here is E. 
hirsutum, L. E. parviflormn, L., is also not infrequent. E. mon- 
tanum, L., is a common weed. E. tetragomwi, Curt, {adnatum^ 
Griseb.), occurs but very rarely. I suggest that the specimens now 
sent are E. lanceolatum x roseum in the third generation, re- 
verting back to the parent, roseum^ conspicuous for their small 
whitish flowers, and the identical serration of leaf as the hybrid ; 
but the narrow lanceolatiwi contour of foliage has disappeared, 
and that of roseum been reassumed. I shall continue watch- 
ing the progeny of the plants in this spot, and expect next 
year they will be quite normal roseujn. — J. Cosmo Melvill. 
I fear these plants and note by Mr. Melvill are not very con- 
vincing. In the first place, the identity of the original plant with 
E. lanceolatuju X roseum cannot be regarded as thoroughly estab- 
lished ; and secondly, as no actual breeding appears to have been 
done, we cannot be sure tliat the plants now sent are the de- 
scendants of the 1907 plant, whatever it was. E. roseian is in 
certain localities a common garden weed. — C. E. Moss. Thoroughly 
typical E. roseum ; no trace whatever of any other origin. — Edward 
S. Marshall. 
Apium nodifloru 7 n^ Reichb. fib, var. [ref. No. 68]. Luffness, 
Haddington, v.-c. 82, August 6, 1910. A large series which I 
collected in the marshes here under different conditions : most 
of them seem to come under longipedunculatum^ F. Schultz ; but 
some may be placed as ochreatu^n^ DC. As the series will show, 
the plants varied greatly according to the conditions in which they 
were found, and in some cases where the plant Avas growing amongst 
long herbage beside a ditch, the branches which extended out into 
the bare mud of the ditch varied so greatly from those which were 
amongst the long grass, &c., as to seem to come under a different
