CHECKLIST OF VASCULAR PLANTS 

Anotated Checklist 1 

OF BONNER AND BOUNDARY COUNTIES, IDAHO 

compiled by 

Marian J. Fuller, Ph.D in Botany 

This checklist of Bonner and Boundary counties contains 1382 vascular plant taxa belonging 

to 109 families and to 460 genera. The families are arranged phylogenetically, not alphabetically. 

Alphabetical indices of the families and genera are provided. The genera are arranged 

alphabetically within the each family, and species are arranged alphabetically within the genus. 

Additional sources and their acronyms: 

(BLM) = McFarlane, S, Kuhman T. and Johnson, C. 2002. Field Guide to Special Status Plants of the 

Cottonwood Field Office. 

(FPNW) = Hitchcock, C. L. and Cronquist, A. 1973. Flora of the Pacific Northwest. 

(PRM). = Kershaw L., A, MacKinnon and J. Pojar; Mousseaux, M.R. 1998. Plants of the Rocky Mountains. 

(IFG) =Idaho Fish and Game (in house document on plants of three recently acquired wetlands) 

(IPNF-RPFG) = Mousseaux, M.R, Idaho Panhandle National Forests--Rare Plant Field Guide (original and 

revised editions). 

(IPNF-) = Idaho Panhandle National Forests (in house document including K = Kaniksu, P = Priest Lake . 

(UIH) =University of Idaho Herbarium, Moscow. 

(USDA) = plants.usda.gov/classification 

Abbreviations: Br = Bonner County; By = Boundary County; Br and By = collected by MJF; Br and By = 

collected or notated by others. See additonal sources 

* = exotic taxon Ida? = maybe first record for Bonner and/or Boundary Counties, many not in FPNW. 

Explanation of the Components of a Checklist Entry:

SEAL 9 10 [Smilacina 11 r. 12 var. 13 a. 14 ] Br;By 15 

1 generic name; 2 specific epithet; 3 abbreivation for Linnaeus, author of specific epithet; 1,2,3 scientific name; 

4 author of “new” species combination; 5 abbreviation for subspecies; 6 subspecific epithet; 7 abbrevation for 

Nuutall,author of subspecific epithet; 8 author of the entire “new” entry; 9 a common name; 10 the synonym used 

in the FPNW (see synonmy); 11 “old” generic name; 12 abbreivation for specific epiteth; 13 abreviation for variety; 

14 abbreviation for variety; 15 collected in both Bonner and Boundary Counties by MJF. 

Synonomy: in this checklist, the synonyms used in the Flora of the Pacific Northwest have been placed within 

brackets, [ ]’s. 

Many genera have been split. For example, the genus Aster has been split into several genera, including 

Canadanthus, Eucephalus, Ionactis, and Symphyotrichum. Sometimes, a species has been determined to be a 

subspecies or variety of an “older” species. Frequently, a subspecies or variety has been deemed distinct enough 

to be elevated to the species level. 

Dedication: to Blue III, Azure and Blue IV, my friends and faithful companions during the thirty years of this 

project. I was never alone. They probably thought “picking posies” was crazy, but they put up with all my 

idiosyncrasies. They are my beloved “hearing-ear” dogs.

INDEX OF FAMILIES 


Two families, Loranthaceae and Nymphaeaceae, have been split. The genus, Arceuthobium, of “old family”, 

Loranthaceae, has been placed in the “new family” Viscaceae. The genus, Brasenia, of the “old family”, 

Nymphaeaceae, has been placed in the “new family” Cabombaceae.
