8 EPILOBIUM NOTES FOR 1889. 



within four or five miles. The determination is clearly correct, 

 though there is a decided leaning towards Lmnyi. The Witley 

 plants were quite unmistakable, being exactly intermediate between 

 the two species. In both localities it was very scarce. 



'^E. Lamyi x obscurum ( E '. semiobscurum Borbas). Near Til ford, 

 and in an ash -plantation on the edge of the wealden near Witley 

 (seeds imperfect) ; both parents being abundant in each case. As 

 it would be natural to expect, this is a difficult hybrid to make 

 certain of, especially when it approaches obscurum ; but my own 

 determination is confirmed by Prof. Haussknecht. Its only 

 previously recorded stations are the Ettersberg, a hill near "Weimar, 

 and Elm, near Brunswick; the latter being very doubtful, as E. 

 obscurum, f. minor, was erroneously assigned by Borbas, who named 

 the Brunswick plant, to this hybrid. 



*E. Lamyi x parviflorum (E. Palatinum F. Schultz). Near 

 Tilford, with the parents. Bather variable, but easily dis- 

 tinguished. Recorded from six German stations. 



E. lanceolatum x montanum (E . neoyradiense Borbas). Scarce, 

 on sunny slopes near Witley, where the two species grow inter- 

 mingled in great profusion. There is a fine series in Herb. Brit. 

 Mus., collected in several stations near Plymouth by Mr. Briggs. 



E. lanceolatum x obscurum [E . Lamotteanum Hausskn.). In the 

 same station as the last, near Witley, but much more plentiful. 

 Here, like the prevailing states of the parents, it is a fine tall plant, 

 often four feet high. It usually occurs in a form nearer obscurum, 

 but distinguishable at a glance by its habit and colouring, and by 

 the stigma being rudimentarily four-lobed ; the flowers are always 

 pale rose, never white at first, as in lanceolatum. A second and 

 scarcer form is liable to be confused with montanum x obscurum. 

 Previously found in Britain by Messrs. Briggs and Trimen, near 

 Plymouth, and Mr. Druce, near Canterbury ; and known on the 

 Continent from three French and two German localities. In the 

 shady lanes I have not succeeded in finding any lanceolatum 

 hybrids, but only in the open. 



E. montanum x obscurum. This will certainly prove to be 

 very common. I have found it abundantly near Tilford, between 

 Hascombe and Dunsfold, in two spots near Witley, and in three 

 near Chiddingfold, always in company with both parents. It has 

 also been sent from Shirley, Derbyshire (leg. Rev. W. R. 

 Linton), and from Rhyader, Radnor, in a very strong form (leg. 

 Hanbury and Ley). In two stations I found specimens with the 

 leaves in threes ; and this verticillate form is in the Perthshire col- 

 lection from three different localities (Perth, Lake of Monteith, and 

 Strathord), shewing that the hybrid is probably frequent in the 

 county. Two states occur, a "f. umbrosa," and a "f. aprica," the 

 latter being always much tinged with red. 



E. montanum x parviflorum. Near Tilford, Chiddingfold, and 

 between Hambledon and Hascombe. Usually the flowers are larger 

 than those of either parent. Very variable in habit and luxuriance, 

 according to the conditions of growth. 



E. montanum x roseum {E. heterocaule Borbas). Near Worples-
