214 PHANEROGAMOUS PLANTS. 



4. Ranunculus orthorhynchus, Hook., 1. c. 



Hab. Nisqually, Puget Sound. — The hairs of the stem are rigid and 

 spreading, not appressed as described and figured by Hooker. The 

 leaves vary greatly, but the species is a very distinct one. 



5. Ranunculus glaberrimus, Hook. 



Hab. Valleys near the Kooskooskee River, Mr. Spalding : speci- 

 mens which accord well with the character and figure given by Hooker 

 (Fl. Bor.-Am. 1, p. 12, t. 5, A.) of this very rare species. 



6. Ranunculus Pennsylvanicus, Linn. 



Hab. On the Columbia River, between the Spokane and Fort Col- 

 ville. — The flowers are larger than in the plant of the Eastern States, 

 but in other respects there is no marked difference. 



7. Ranunculus tenellus, Nutt., in Torr. & Gray. 



Hab. Nisqually, Puget Sound. [In Proceed. Amer. Acad. 8, p. 374, 

 this is combined with the next, under the name of R. Nelsonii, var. 

 tenellus, Gray.] 



8. Ranunculus occidentalis, Mitt., 1. c. 



Var. parviflorus : floribus multo minorlbus ; stylis carpello subhispido 

 longioribus. 



Hab. Plains between Puget Sound and the Cascade Mountains. — 

 This variety differs from the ordinary form of R. occidentalis in the 

 very small flowers, which are not larger than those of R. recurvatus. 

 The stem is about a foot high, and thinly clothed with retrorse-spread- 

 ing stiffish hairs. The leaves are as in R. occidentalis. Petals oblong, 

 scarcely exceeding the sepals. Carpels hispid with a few hairs, which 

 are mostly situated on the back. [This plant is the R. Mlsonii, forma 

 typica, Gray, 1. c]
