 Synopsis, p. 67. 



Root fibrous. Stems tufted, procumbent at the base, simple, or 

 with several short slender spreading leafy branches from below, pani- 

 culated above, round, smooth, or mostly clothed with soft spreading 

 hairs, four to eight inches high, much crowded with leaves at the base, 

 scattered above. Leaves linear lanceolate, mostly with a short bristle 

 at the point, flat on the under side, slightly convex on the upper, 

 somewhat fleshy, ciliated, with stout pale bristles, sometimes nume- 

 rous, more frequently scattered, rarely quite smooth or serrato-ciliated, 

 and below the apex is a glandular pore. Injlorescence a terminal 

 branched sub-corymbose panicle, with downy glutinous branches, 

 mostly of numerous flowers, sometimes but rarely there is only a soli- 

 tary terminal flower. Flowers a bright yellow, beautifully spotted with 

 orange : when the whole of the petals are of an orange colour, it is the 

 variety ^. crocea of Gaudin and others. Calyx of five ovate obtuse 

 spreading segments, united at the base, and when in flower appearing 

 inferior, but when in fruit it surrounds the capsule about the middle. 

 Petals oblong, obtuse, rather longer than the calyx, three ribbed, 

 spreading. Stamens witli awl-shaped filaments, nearly as long as the 

 petals. Anthers ovate, of two cells. Styles thick, with depressed 

 stigmas. Capsule somewhat globular, crowned by the styles. Seeds 

 iiumerous, ovate, triangular, rugose. 



Habitat. — Alpine districts, in damp places; abundant in the North 

 of England, Wales, Scotland, and Ireland. 



Perennial ; flowering from July to September. 



The yellow Mountain Saxifrage is an extremely pretty little moun- 

 tain plant ; its bright golden flowers elegantly spotted with red, gaily 

 decorate the damp places and margins of the rills, often in great abun- 

 dance, forming close patches ; and in similar damp places amongst 

 artificial rock work it flourishes well, and flowers freely.
