Hab. Near mountain springs and streams, not uncommon between the Kettle Falls, *' and Narrows" 

 of the Columbia River, N.W.C. Douglas.~li differs somewhat from the genus, and even from the tribe, 

 by the absence of any style: but, besides the characters taken from the flower, the Erythracacece are so 

 well marked by their inflorescence, that I am of opinion the present would be the most convenient 

 place for this species. I have seen only one specimen, which was already in a very advanced state. Ex- 

 acum pulchellum, Pursh, which I have not yet obtained, may be another North American species of this 

 genus, with which Orihostemon, Br., may perhaps be not improperly joined, as it seems to differ only by 

 its stigma, the characters of which are at least variable in ErythrtBa and Canscora.
