great plenty about the slate quarries, &c., in the Plym Valley. 

 Newnham. About Plympton. Bickleigh. 

 V. Brixton village, Winstone, on slaty refuse by CofReet Lake, and 

 elsewhere in Brixton parish. Near Lynham. Yealmpton. 

 Between Cornwood Railway Station and the village ; near tlie 

 latter at 400 feet. 

 YI. Kingston, in a lane close to the village, also by the road to Scots- 

 combe, and near Cling Mill. Holbeton ; half-a-dozen plants 

 in a lane leading thence towards Flete, 1874. Strood, and 

 elseAvhere near Ermington. About Ivybridge. On refuse from 

 the slate quarries between Ivybridge and Ugborougli and else- 

 where near Ugborough. 

 The profusion of this Epilobium in many parts of the area is a very 

 striking and remarkable botanical fact. Whilst so abundant over a con- 

 siderable extent of country, it is, however, rare or absent from certain 

 localities. It ascends to above 500 feet near Roborough village (District 

 III.), but grows mostly m low, warm situations, especially where slaty or 

 shaly soils prevail, though not confined to them. It may often be seen 

 growing abundantly on banks or ' cuttings ' by the railways. Like some 

 other species, it seems to be rapidly extending its range. In this neigh- 

 bourhood it would seem to have either remained unnoticed, or else to 

 have been confused with some of the other species of the genus, until I 

 directed attention to it in Phijt. vi. N.S. 287, bemg the volume for 1862. 

 It had, however, been preriously recorded for Devon in Watson's SupYth- 

 ment to tJie Cyhele Britannica, 1860 ; and there are specimens in Herb. 

 Borrer. at Kew, labelled, " Blackpool, near Stoke Flemmg, Devon, 1853," 

 doubtless collected by the late Mr. Borrer. The flowers difier obviously 

 in colour from those of E. montanuyn, being of a rosy or pinkish, not 

 purpHsh, hue ; they open of a pure white, but soon assume colour. The 

 plant begins to flower about the same time as E. montanum. 



291. E. roseum, Schreb. Small-flowered Smooth Willow-herb. 



Casual or Colonist. Very rare or extinct. June to September. 

 D. III. One plant by the side of the footpath in front of Stopford Place, 

 Stoke Damerel, August, 1863. One as a weed in the garden of 

 the chaplain's house, Devonport Dockyard, August, 1865. 



292. E. tetragonum, L. Long-podded Square-stalked Willow-herb. 



Native ; by damp roadsides, and in waste places. Rather common, 

 but with local tendencies. July to September, or later, 

 c. I. Between Antony and Tregantle ; rather sparingly, 1875. Near 

 the old slate quarry at Wivelscombe. Between Landrake and 

 Tideford, and at the latter place. St. Germans, by a road near 

 the railway station.
