RANUNCULUS REPENS. L. Creeping crowfoot. 



Calyx spreading ; flower stalks furrowed ; sci- 

 ons creeping ; leaves compound. L. 



' 



The flowers of this and the two last are very similar, and 

 confounded under the common name of Butter cups. An at- 

 tention to the calyx and flower stalks readily distinguishes them. 

 In this the leaves are mostly ternate, lobed and toothed, often 

 marked with a light spot at their sinuses. The plant sends out 

 long, prostrate stems or runners, which sufficiently distinguish 

 it from the others. Flower stalks furrowed as in Ranunculus 

 bulbosus, calyx spreading as in Ranunculus acris. Petals 

 bright yellow, often emarginate. Shady places. Flowering aii 

 summer. Perennial . 



RANUNCULUS FLUVIATILIS. River crowfoot. 



Leaves all dichotoraous, capillary ; stem float, 

 ing. Willd. 



Syn. RANUNCULUS FLU IVANS. Poir. 



This is undoubtedly a distinct species from Ranunculus 

 aquatihs, having its leaves all capillary in the stillest water. 

 Its flowers are yellow. Stem long, smooth, furnished at regu- 

 lar intervals with nearly sessile leaves, divided by regular forks 

 into innumerable capillary segments. The flowers only 

 emerge from the water, Peduncles smooth, furrowed. Calyx 

 leaves fleshy, concave. Petals smaller than in Ranunculus bul- 

 bosus. Nectaries tubular. Fruit in ovate heads, the seeds 

 ending in a long, sharp point. In a pond on Brighton road and 



elsewhere in deep water. June. 







172. MAGNOLIA. 



MAGNOLIA GLAUCA. L. Beaver tree. 



Leaves elliptic, obtuse, glaucous underneath ; 

 petals obovate.
