---|---|
Acer glabrum + | Leaves opposite on stems. Leaves with 3-5 lobes. Leaf margins coarsely toothed. + |
Achillea millefolium + | Leaves alternate on the stem, deeply dissected into narrow segments + |
Aconitum delphiniifolium + | Alternate, long stalked near base of plant, stalks reduced upwards on stem. Leaves divided to the base into 5 lobes, margins toothed or occasionally smooth. + |
Adiantum aleuticum + | Fronds fan-shaped, pinnules gnochi-shaped, leaf margin covers developing sporangia. + |
Alnus rubra + | Leaves alternate on stems. Leaf blades oval to elliptic with toothed margins. Leaf edge rolled under, under surface of leaf has dark green edge. + |
Alnus viridis + | Leaves alternate on twigs. Leaf blades oval to elliptic with finely toothed margins. + |
Anaphalis margaritacea + | Leaves are alternate on the stem. Leaves narrowly lanceolate or oblanceolate. Leaves largest on the lower stem. Underside with white wooly hairs, upper surface somewhat less hairy. + |
Andromeda polifolia + | Leaves alternate, narrowly elliptic to linear with a sharp point. Leaf margins are rolled under. Upper surface dark or medium green with sunken lighter colored veins + |
Anemone narcissiflora + | Leaves basal, leaf-like bracts are below each flower cluster. Each leaf palmately divided into 3 leaflets, each leaflet deeply lobed. + |
Angelica genuflexa + | Leaves both basal and alternate on stem. Leaves divided in 9 to 12 oval to elliptic segments. Leaf margins serrate. Leaf tips bent back toward ground. + |
Angelica lucida + | Leaves both basal and alternate on stem. Leaves divided in 3 main parts, then each part divided in 3 to 6 oval to elliptic segments. Segments irregularly lobed and serrate. + |
Antennaria rosea + | Basal leaves lance-shaped, broadest between middle and apex of leaf. Stem leaves alternate, with sharp pointed apex + |
Aquilegia formosa + | Leaves are divided into 9 wedge-shaped leaflets. The leaf axis is divided into 3 stems which each form 3 leaflets. Each leaflet is divided at the tips into 3-5 round tipped lobes. + |
Arnica chamissonis + | 4-10 pairs of sessile stem leaves. Basal leaves may have short stalks and are usually withered by flowering. Leaves lance-shaped with entire to few toothed margins. + |
Arnica griscomii + | 1-4 pairs of opposite leaves. Leaves lanceolate, ovate or spatulate with toothed margins. + |
Arnica lanceolata + | Leaves opposite on stem, usually without stalks, to 5 inches long. Usually 5 to 12 pairs of stem leaves. The lowermost pair of leaves is smaller and withers by flowering. Leaves with toothed margins. + |
Arnica latifolia + | Leaves opposite on stem, stalkless or with a very short stalk. 2 to 4 pairs of leaves per stem. Leaves with toothed margins. Basal leaves much smaller than stem leaves, usually withering by flowering. + |
Arnica lessingii + | 3-5 pairs of leaves crowded toward base of stems. Leaves with stems or sessile, blades elliptic or oblanceolate. Margins often toothed from middle to tip. + |
Arnica ovata + | Leaves in 2-3 pairs on stem. The upper most pair are stem-less, but the lower leaf pairs have broad stems. Leaves are broadly ovate with coarsely toothed margins. + |
Aruncus dioicus + | Leaves alternate on stem, on long stalks. Overall leaf shape is triangular. Leaf blades divided in several ovate segments. Leaf margins with toothed margins + |
Asplenium trichomanes + | Fronds less than 1 inch wide, frond divided in many paired segments (pinnae), pinnae ovate to rhombic, sporangia in 3-5 pairs on underside of each pinnae. + |
Asplenium viride + | Blades less than 1 inch wide, frond divided in many paired segments (pinnae), pinnae ovate to rhombic, sporangia in 2-4 pairs on underside of each pinnae + |
Astragalus alpinus + | Pinnately compound, each leaf with an terminal leaflet. + |
Athyrium alpestre + | Blades 2-3 times pinnate. Indusia are absent or very small. The Sori are round and submarginal + |
Athyrium filix-femina + | Fronds broadly lance-shaped to elliptic in outline. Fronds divided in segments (pinnae) which are also divided. Clusters of sporangia are horseshoe or half-moon shaped. The clusters are located near the medial line on the lower surface of frond. + |
