Greene's species as based on more adequate and normal 

 material. 



Ranunculus terrestris sp. nov. A small, delicate perennial, 

 growing in damp or swampy places, from a fascicle of thick but 

 long and slenderly tapering fleshy-fibrous roots; leaves on 

 delicate, almost filiform petioles; petioles of the basal leaves 1-4 

 inches long, those of the cauline leaves 1/4 to 1 inch long or 

 sometimes the terminal pair of leaflets sessile, somewhat 

 sparsely pilose-hairy; the lamina broadly ovate or deltoid, 

 rarely lanceolate, sometimes almost round, usually obtuse at 

 the apex but sometimes rounded, very rarely acutish, perfectly 

 entire, 1/4 to 3/4 inch long, the larger ones rounded at the base 

 delicately membranous, glabrous; stems several from the 

 fascicle of fleshy roots, somewhat pilose-hairy, simple or with a 

 few very rudimentary branches, prostrate for most of its length 

 erect or ascending at the terminal part, very rarely having a 

 few delicate rootlets from the prostrate nodes; the erect termi- 

 nal part usually with a pair of approximately opposite leaves, 

 which are sometimes sessile and very much reduced, bearing a 

 single small waxy-yellow flower 8mm. wide when fully open; 

 petals 5 oblong or orbicular, twice the length of the sepals; 

 achenes small, glabrous, moderately compressed, with a slender 

 beak 1/2 to 1/3 the length of the body. 



Differing from Ranunculus flammula var. reptans in the 

 distinctly wider leaves and in somewhat longer styles. 



Since Greene's plant is here regarded as merely an abnormal 

 form of this proposed new species we would include it as a 

 synonym. 



The type has been deposited in the Herbarium of the Uni- 

 versity of Oregon as: — Wynd, no. 2086, Red Blanket Creek in 

 the southwest corner of Crater Lake National Park. Other 

 specimens in the University of Oregon Herbarium which have 

 been examined and referred to this species are those of Sheldon, 

 no. S12457, Lake Valley, Lane County, Oregon, July 17, 1903.
