60 POLYANDRIA— POLYGYNIA. Caltha. 



/3. In similar situations, but much less frequent. Sent from Cum- 

 berland to Mr. Forster, in whose garden it remains unaltered. 



Perennial. March, April. (3. Mmj. 



Root thick, and somewhat tuberous, with many simple fibres. Stem 

 12 or 18 inches high, erect, round, hollow, leafy, branched, fur- 

 rowed. Leaves variously heart-shaped, crenate ; the lowermost 

 on long, somewhat triangular, /oois^a/Ars, largest, most rounded, 

 and with blunter notches 5 upper nearly sessile, alternate, more 

 triangular, acutely crenate. Stipulas membranous, withering. 

 Fl. several, from 3 to 5, large, bright yellow, on alternate soli- 

 tary stalks. Pet. 5, an inch long, roundish-oval. The flower- 

 buds pickled serve for Capers, which they resemble, except in 

 having numerous germens. A double variety is frequent in 

 gardens. 



/3 is in every part but half the size of the common sort j the stems 

 are more reclining, each bearing 1, 2, or SJlowers, whose petals 

 are but half an inch long, yet I can find no decisive specific cha- 

 racter. Possibly this variety may render the following species 

 somewhat doubtful ; but they require careful examination in a 

 wild state. The cut of Tabernaemontanus does not at all re- 

 semble our /3 in the foliage. 



2. C. 7'adica?is. Creeping Marsh-marigold. 



Stem reclining, creeping. Leaves triangular, somewhat 

 heart-shaped, sharply crenate.

By the sides of lakes and rivulets in Scotland. 



First observed in Scotland by the late Mr. Dickson. Near Forfar. 

 Mr. G. Don. About the Pentland hills, and in Roslyn woods -, 

 Dr. Greville : more common in some spots near Edinburgh, 

 than C. palustris ; Mr. Arnott : marshes near Collace, Perth- 

 shire -f Mr. Maughan. Hooker. 



Perennial. Maij, June. 



This is scarcely half the size of our common C. palustris. The re- 

 cumbent stems send forth roots from several of the lower joints, 

 creeping to a considerable extent. Leaves from 1 to 2 inches 

 broad, more triangular than heart-shaped, sharply crenate ; the 

 radical ones on very long s\ei\der footstalks. Petals the colour 

 of the foregoing, about half as large, more obovate, or sometimes 

 obliquely wedge-shaped. Germens 7 or 8. A double variety of 

 this is cultivated about London.
