26 POLYANDRIA— MONOGYNIA. Cistus. 



hairy, twisted in the bud. Pet. longer or shorter than the ca- 

 lyx, yellow, lanceolate, partly notched or serrated. Stam. some- 

 times very short, as if imperfect. Gennen densely hairy. Style 

 bent. Caps, with 3 very slight partitions. 

 Mr. Lightfoot in his herbarium has noted the depressions on the 

 backs of the leaves, which, with other marks, clearly determine 

 this as a species, though it has never been found but in Surrey.

Of a more dwarf habit than the last. Root woody, bearing many 

 procumbent, or slightly ascending, round, downy, simple, leafy 

 stems, each terminating in a simple downy cluster, of bright 

 yellow^oti;ers, expanding in sunshine only, when their stamens 

 if touched spread slowly, and lie down upon the petals. Brac- 

 teas lanceolate, smooth, fringed, one at the base of each flower- 

 stalk. These partial stalks are slender, hoary, various in direc- 

 tion, more reflexed as the fruit advances. Calyx smooth, or 

 scarcely at all downy, between the strong bristly ribs of its 3 

 larger reddish leaves ; the 2 outer leaves ten times smaller, 

 spreading, lanceolate, mostly acute, green, smooth on both 

 sides, their edges fringed with numerous bristly hairs. Germen 

 globose, downy. Capsule with very narrow receptacles, or im- 

 perfect partitions. The leaves of this species vary in breadth, 

 and are more or less revolute ; green above, besprinkled with a 

 few hairs ; densely downy, white, and hairy beneath. Their 

 usual form is linear-oblong, somewhat elliptical. Stipulas lan- 

 ceolate, acute, fringed, green on both sides, longer than the 

 footstalks. 



Ray says the flowers are very rarely white j they are sometimes 

 double in gardens. This is a variable species, but less so than 

 authors make it, Few plants are more difficult to define than 

 the smaller kinds of Cistus. The roseiis and mu tabi lis of J acqmn
