SHORT NOTES ll5 



crowded, narrow leaves ; this, I feel sure, is one parent of the 

 other two. The second he has compared with my description of 

 Mr. Waterfall's Cheshire hybrid (pp. 75-6) ; and he is confirmed 

 in his original opinion that it is E. hirsutum X palustre. I fully 

 agree ; but the three sheets forwarded are considerably nearer to 

 E. hirsutum, in foliage and general appearance, than the Cheshire 

 specimen. A slightly immature capsule contains shrunken seeds. 

 Magenta or crimson would be a better word than rose to express 

 the floral colour. The third gathering consists of two rather 

 small plants, which Mr. Compton independently suggested might 

 possibly be E. adnatum x imlustre ; E. tetragonum ' L.,' Curt., 

 var. stc7iop]iyllum Druce [E. adnatum Grisebach, forma stenophylla 

 Haussknecht) grew at the spot. Their general habit is that of 

 an E. 2:)alustre with crowded, narrow, erect foliage ; but I am 

 convinced that they cannot be that species, pure and simple. The 

 leaves are erect, narrow, parallel-sided, more or less denticulate 

 (in E. pahistre they are always quite entire), and frequently some- 

 what adnate-decurrent ; they also approach E. tetragonum in 

 colour, texture, clothing, and especially in the venation of the 

 lower ones. There are slight indications of decurrent lines on the 

 slender, far less hairy stems ; and the flowers look fairly inter- 

 mediate. Capsules about half as long as those of the accompany- 

 ing E. imlustre ; their pubescence more scanty, not so grey, nor 

 so closely appressed. This is the first occurrence known to me of 

 E. palustre x tetragonum as British, in a wild state, though a very 

 different form of the hybrid occurred spontaneously in my garden 

 at Milford, Surrey, in 1894 ; it was inadvertently included in the 

 10th edition of the London Catalogue, The Dungeness specimens 

 may, perhaps, be due to a recrossing with E. palustre ; but I do 

 not think so, on the whole. — Edward S. Marshall.

The Thirty-first Annual Beport of the Watson Botanical Exchange 

 Club, 1914^1915. Cambridge : J. Webb & Co. 



This latest Eeport is, as usual, edited by Mr. George Goode, 

 the Hon. Secretary of the Club, the task of distribution for the 

 year having been undertaken by Miss Ida M. Eoper, who is also 

 one of the principal contributors of specimens. Miss Eoper 

 reports favourably both as to the quantity and quality of the 

 specimens sent in ; in the former respect Mr. J. E. Little, whose 

 notes seem to us especially interesting, stands as an easy first 

 with 691 specimens ; Mr. J. W. White comes next with 369 ; and 

 Miss Eoper, Mr. Spencer Bickham, and the Eev. E. S. Marshall 

 follow with 302, 287, and 283. The Eeport also contains 

 Dr. Vigurs's sketch of the late F. H. Davey, with the portrait 

 which we were allowed to reproduce in our January number. 



As in the case of the Botanical Exchange Club, the Eeport is 

 largely concerned with critical genera, the notas on which will 

 mainly interest specialists. There are, however, a large number 

 of observations of more general interest, and some of these,
