ICOSANDRIA POLYGYNIA. 117 



156. GEUM. 



1. G. urbanum, leaves ternate, radical ones somewhat lyrate ; 

 stipulas rounded, cut; flowers nearly upright, small, yellow; 

 styles naked. Common Avens. 



Hab. Woods and hedges, frequent. May-Aug. 7/ 



Formerly in high repute for all relaxations of the bowels ; 

 and, from its astringent and tonic power, deserves to be 

 revived. Its taste is aromatic and austere Dr GOOD. 



2. G. rivale, radical leaves interruptedly pinnate, somewhat ly- 

 rate ; stipulas ovate, acute, cut ; flowers drooping, large, with a 

 purplish-brown calyx and tawny brown petals ; styles ' hairy 

 above the curvature. Water Avens. 



Hab. Sides of rivulets and ditches, and in boggy woods, 

 common. June, July. 11. 



The variety /3, considered a hybrid plant by some, but erro- 

 neously, is found in the woods at Netherbyres, according 

 to Mr BAIRD, and has occurred to us in the immediate 

 neighbourhood. In it the stalk supports a showy rose-like 

 flower, consisting of numerous red striated petals, with- 

 out any calyx, the segments of which have been converted 

 into leaf-like bracteas. From the centre of this another 

 flower, generally of the usual conformation, arises, and its 

 stalk bears near the base 3 lacineated bracteas, very much 

 resembling in colour and texture the true petals; but 

 monstrosities are never constant in character, and two 

 specimens will seldom be found to correspond precisely. 



157. COMARUM. 



1. C. palustre, downy ; leaves pinnate, the lower with 7 or 5 

 elliptical serrated leaflets, the upper with 3 ; flowers dark pur- 

 plish red, the petals much smaller than the calyx. Marsh Cinque" 

 foil 



Hab. Spongy bogs and marshy places, frequent. Below

 wood-hall, Dr Thompson. Longridge dean, &c. July.
