[Aconitum Fischeri, Reichenbach, has not yet been found in British America ; but 

 occurs in Alaska and in Washington Territory, where it was first found by Douglas on the 

 "Wallawallah River, a branch of the Columbia ; it ranges to Kamtschatka, and one form 

 {ft. arcuatum) occurs in Mandschuria ; in America it reaches south to California, rising to 

 8000 feet on the Sierra Nevada. Smooth or slightly pubescent ; leaA'^es palmately cleft, 

 the 5 (or 3) segments being rather widely cuneate, and incisely toothed, the lobes rhombic-
