RANUNCULACE^. -q 



nished with a conspicuous two-cleft appendage on the short claw, 

 scarcely exceeding the sepals in the later flowers, which the speci- 

 mens alone furnish. Achenia 2 lines or more in length, including 

 the stout and rather conspicuous subulate beak, which is more or less 

 recurved, in shape very broadly semiovate or dolabriform, compressed, 

 scarcely margined, smooth, aggregated into a globular head of half an 

 inch in thickness when full-grown. 



This coarse and stout, pretty well-marked species may be compared 

 with the Mauritanian Ranunculus sericeus, Poir., figured by Delessert; 

 but that has the divisions of the less dissected leaves sessile, much 

 narrower sepals, and an oblong head of smaller and short-pointed 

 carpels. In ours the achenia are remarkably large for the size of the 

 flowers.

R. parce hirsutus, nunc glabratus; caule ramoso elongato decumbente; 

 ramis in paniculam laxam foliosam diliquescentibus ; foliis caulinis 

 trisectis, divwionibus petiolulatis vel sessilibus ovatis bi-tri-lobatis, lobis

Stem apparently attaining several feet in length, slender, much 

 branched above, reclining or ascending, hirsute with a scattered 

 pubescence, in general appearance nearly glabrous. Leaves trisected, 

 membranaceous, minutely and sparsely hairy, but appearing nearly 

 glabrous; the lower cauline on long petioles; their divisions ovate, 

 short-petioled or sessile, 2 or 3 inches long, sharply serrate all
