Abstract
This study dealt with the Intermountain aconites of which the chromosome number of n = 8 was obtained.
The bumblebees, Bombus rufocinctus Cresson, B. appositus Cresson, and B. centralis Cresson, are the major pollinators of the allogamous and autogamous aconites.
Two-dimensional thin layer chromatography of cauline leaf extracts showed that the Intermountain aconites studied here consist of one chemical group.
The overall evidence indicates that the Intermountain aconites consist of one species, Aconitum columbianum Nutt., with two varieties, variety columbianum and variety ochroleucum A. Nels.
