was discovered in Philadelphia, and a paper concerning it pub- 

 lished by the late Thomas Meehan. Among the plants is a 

 good flowering stalk of the plant called Clematis Donglasii^ 

 which not only fits the description of Pursh's species, but is 

 found more or less abundantly in the very region where Lewis 

 collected the type. On the contrary, Anemone patens var. Nut- 

 talliatta^ or Pulsatilla hirsutissima^ as it has recently been called, 

 is found ver}^ sparingly if at all west of the Rocky mountains. 

 With such evidence, Clenmtis Doiiglasii should undoubtedly be 

 / treated as a synonym.

This is certainly quite distinct from R. canus when com- 

 pared with typical specimens of that species. Besides differing 

 considerably in gross appearance, R. Blankinsliipii has a very 

 large, thin, hispid-papillose akene, the body of which is broadly 

 ovate, tapering gradually to a triangular, almost straight point. 

 In R. camis the akenes are smaller, sub-rotund, with a short,, 

 strongly hooked beak.

The t)^pe of Spiraea discolor Pursh, was collected by Lewis 

 <'on the banks of the Kooskoosky" or Clearwater river, in north- 

 ern Idaho, where the writer has seen it in abundance. In fact, 

 it is abundant throughout northern Idaho and eastern Washing- 

 ton, but only at elevations of probably less than 2000 feet, pre-
