6 EPILOBIUM NOTES FOR 1889. 



It seems to vary almost indefinitely, especially in the North. Mr. 

 Miller sends several forms from Caithness and Sutherland, and Mr. 

 Beeby others from Shetland. I found a white -flowered state in 

 Glen Falloch, Perthshire, and one with flesh-coloured flowers near 

 Kingshouse, Argyle. 



Var. lapponicum Wahlenberg (ex parte) occurred very sparingly 

 in a small bog near Kingshouse, Argyle, at 2000 ft., with E. ana- 

 gallidifolhm, and I rather suspected it to be a hybrid. The stem 

 is short (5 or 6 inches in my specimens), stout, erect from a curved 

 base, few-flowered, nodding at the top, the lower leaves being 

 obovate, more than half as broad as long, glabrous, fleshy and rigid, 

 broadly rounded at the tip ; the upper ones almost veinless, sub- 

 glabrous ; the flowers small (| in.), white or pale flesh-coloured. 



E. alsinefolium Vill. Specimens brought from Clova, last 

 year, developed greatly in a shady corner of my garden, producing 

 leaves nearly an inch broad, and flowers quite I in. across, when 

 fully expanded ; but did not attain the luxuriance of a form found 

 by Mr. Hanbury and myself in one of the side-valleys of Glen 

 Etive, Argyle, which in some cases was 18 or 20 inches high. It 

 grew in a mossy rill, at 2G00 feet. 



E. anagallidifolium Lam., f. scapoides. In the same locality 

 with the last-named plant. Mr. W. F. Miller also gathered it in 

 1888, on Ben Lawers. In this state the capsule seems like a 

 prolongation of the stem, which has thus a scape-like appearance. 

 It is described as single-flowered, but some of my specimens are 

 three-flowered. 



I have been able, thanks to Mr. Hanbury, to carefully examine 

 Dr. Boswell's willow-herbs, and can confidently say that, although 

 he figures two plants in E. B., ed. 3, as " E. alpinum" and " E. 

 anagallidifolium" (I have not seen these figures recently), all his spe- 

 cimens under both names are the present species, with the possible 

 exception of a Braemar plant, which may be a hybrid. The same 

 remark applies to the various specimens in Herb. Brit. Mus., and 

 to the Perthshire set sent to me by Dr. White. 



*E. adnatum x Lamyi (E. semiadnatum, Borbas). Near Tilford ; 

 between Hambledon and Hascombe ; and hi a wealden copse near 

 Witley. Some of the specimens shew an approach to Lamyi, while 

 others are nearer adnatum. As a rule, the leaves have little 

 tendency to be decurrent by their blade, as in the latter species, 

 but are shortly petioled. On record from some half-dozen localities 

 in Germany, Switzerland, and Hungary. 



E. adnatum x obscurum. Sandy ground near Tilford; very 

 scarce. Quite a different form from that found last year near 

 Witley, having grown in a drier situation and on a lighter soil. 



E. adnatum x parviflorum (E. Weissenburgense F '. Schultz). In 

 the same locality as the last, and also very scarce ; approaching 

 adnatum in the flowers, and parviflorum in the leaves. I believe it 

 has only been gathered before in Britain by Mr. Briggs, though 

 known from twenty Continental stations. Several Plymouth 

 specimens are at S. Kensington. 



*E. hirsutum x lanceolatum (E, Surreyanum niihi), hybr. now
