a small tuft or very lax rosette. Lower leaves obovate or oblan- 

 ceolate, attenuated into a petiole ; stem-leaves sessile, elliptical or 

 strap-shaped, entire or faintly callously denticulate, nearly destitute 

 of cilia?. Flowers terminal, solitary, rarely 2 or more. Sepals 

 free, oblong, obtuse, ciliated, reflexed. Petals three or more times 

 as long as the calyx, oblong, ascending-spreading, bright yellow 

 dotted with red in the basal half, and with 2 callosities at the 

 base. Capsule wholly superior. 



In wet moors. Very local. Knutsford Moor, Cheshire ; Cother- 

 stone - Fell and Teesdale, Yorkshire ; Langton, Berwickshire ; 

 Walston, Lanarkshire ; Ochill HiUs, near Dollar, Clackmannan- 

 shire (Dr. Wyville Thomson). 



England, Scotland, Ireland. Perennial. Autumn. 



Stems branched below ground, and producing close to the 

 surface slender stolons, somewhat resembling those of Epilobium 

 obscurum, except in having the leaves alternate. Stems 3 to 8 

 inches high, simple below, rarely branched at the top. Hoot-leaves, 

 including the stalks, f to 2 inches long ; stem-leaves ascending, 

 I to 1 inch long, diminishing in size towards the top of the stem. 

 Flowers f inch across. Petals obovate, obtuse, 5 -nerved (the 

 central nerve giving off 2 forked branches from a little above the 

 base, as in S. oppositi folia), bright yellow thickly dotted with red 

 towards the base. Stamens shorter than the petals. Capsule, 

 exclusive of the short diverging beaks, f inch long, much longer 

 than broad, reddish-brown. The ripe seeds I have not seen, but, 

 according to Grenier and Godron, they are white and shining. 

 Plant yellowish-green, glabrous except the upper part of the stem 

 and sepals, and occasionally a few cilise on the margins of the 

 leaves.
