RANUNCULACEAE. 



Ranunculus parviflorus L. 



Ranunculus parviflorus L., Sp. PI., 1763, Ed. ii, 780. 



In the forest below Kaalapuuwale ou the slopes of Hualalai 

 on the island of Hawaii, occurs a species of Ranunculus which 

 I refer to the above. This diffuse plant with minute yellow flowers 

 and hispid carpels covers many acres ; mainly in the dead Koa 

 forest, although some specimens were found in virgin forest. 

 This place is also a localit}' for R. mauiensis, the two species 

 often growing close together ; while within a mile can be found 

 R. hawaiiensis, the other native species. My determination is 

 based on the description found in Britton and Brown's Flora of 

 the Northern States and Canada.
