268 DECANDRIA— DIGYNIA. Saxifraffa. 



Chamaecistus Frisicus. Ger. Em. 1284./. 



In turfy bogs, very rare. 



In a morass about the centre of Knutsford moor, Cheshire, where 

 Dr. Kingstone first pointed it out to Dr. Richardson, early in 

 the 18th century, and from whence Mr. Okell of Chester sent 

 the wild specimen delineated in Engl. Bot. in August 1801. 

 On Cotherstone fell, near the junction of the Blackbeck with 

 the river Balder, Yorkshire, found by Mr. John Binks, some of 

 whose specimens were given me by Mr. James Backhouse. 



Perennial. August. 



Root tufted with numerous black fibres, sending forth from the 

 crown many short, simple, decumbent, leafy shoots, often 

 clothed with loose, rusty hairs. Stems solitary, simple, erect, 

 from 4 to 8 inches high, leafy, round, reddish, generally smooth, 

 sometimes shaggy with rusty hairs. Leaves scattered, lanceolate, 

 obtuse, entire, bright green, smooth, except a few occasional 

 soft marginal hairs ; tapering at the base into a smooth foot- 

 stalk, various in length. Flowers terminal, corymbose, usually 

 2 or 3, sometimes solitary ; their stalks hairy and glutinous, 

 with a linear bractea to each. Cal. spreading at the first open- 

 ing of the /lower, but soon becoming refiexed, being altogether 

 inferior, as in the first section ; segments oblong, concave, ob- 

 tuse, .5-ribbed, minutely fringed. Pet. twice as long as the 

 calyx, spreading, obovate, deep yellow copiously dotted with 

 red, having many simple unequal ribs, confluent above the base, 

 which ends in a short claw, and is marked with a nectariferous 

 furrow, bordered by two prominent pointed valves. Stam. 

 shorter than the petals. Caps, oblong, tipped with the short 

 angular styles, and broad, rounded, convex, downy stigmas. 

 Seeds numerous, ovate, ribbed, of a shining brown. 



A beautiful species, agreeing in its calyx and capsule with the 

 first section, but hardly allied, by habit or peculiar characters, to 

 any of the genus besides, except perhaps the following.
