228 EPILOBIACEAE 



E. montanum is found in several varying forms, including 



Var. VERTiciLLATUM, Koch, Syn. 240 (1837), with leaves in whorls of 

 three instead of in pairs, which occurs in Wytham Wood, Unwell Wood, 

 and Bracknell. See Rep. of Bot. Exch. Club (1888) 219. 



A white-flowered form,/, albiflora, has been seen in Unwell Wood, &c. 



In shady places in Wytham and near Padworth, &c., the /. umbrosa, 

 Haussk., has been observed. Near Hurst a form or variety occurs, 

 with something of the look of E. coHinum, in which the upper leaves 

 are more deeply cut. A very large-leaved form, /. grandifolia, Haussk., 

 occurs near Early, &c. Near Bracknell, Kintbury, and Hermitage 

 a form occurs (/. oprica) which is similar to the so-called E. Duriaei, 

 figured in Journ. Bot. (1896) ; it is probably not uncommon in the 

 heathy districts, and has also been seen on chalk rubble near Beading. 



At Padworth E. fnontanum occurred with dark-red flowers, but not 

 difl'ering in other respects from the type. 



E. montanum affords several hybrids. 



X E. MONTANO-OBSCURUM, F. Schultz in Jahresb. Pollich. 1857 (?j&. 



aggregatum, Celakovsky), which has been noticed near Hermitage, near 



Hurst, and near Aldermaston. 



X E. MONTAKO-PARViFLORUM, Michalet in Bull. Bot. Soc. France, ii. 



(1855'] 734 (E. liinos^im, Scliur), which has been noticed nearUffington. 



X E. MONTANO-ROSEUM = E. moutanum, var. parvijlorum, Wahl. Fl, Suec 



i. 242 (1831), E. heierocaule, Borbas, which was found on waste ground 



near Reading, where both parents occurred. 



For a very interesting account of hybridization of this species, a paper by 

 Dr. T. Bell-Salter, which appeared in Phyt. (1852) 737-42, should be consulted. 



E. montanum occurs in all the bordering counties. 



E. lanceolatum, Sebast. et Mauri, Fl. Rom. Prod. 138 (1818). 



Top. Bot. 161. Syme, E. B. iv. 14, t. 500. Nyman, 247. 



Native. Septal. Hedge-banks and ditches on gravelly soil. Very 



local and rather rare, occurring in a very restricted area. P. 



July -September. 

 First found in Berkshire by the author in 1888. 



4. Keiinet. Mortimer. 



5. Loddon. Between Mortimer and Silchester, and between Mor- 



timer and Strathfieldsaye. 

 The/, umbrosa occurs near Strathfieldsaye in Berkshire. 

 X E. LANCEOLATO-OBSCURUM — (E. Lam.otteanum, Haussk.) has been 

 found by me near Mortimer, and Prof. Haussknecht assents to the name. 



X E. LANCEOLATO-ROSEUM. Discovered by me in 1888 near Mortimer 

 growing with both parents, and kindly named for me by Prof. 

 Haussknecht. 



E. lanceolatum is recorded for Surrey, Hants, and W. Gloucestershire.
