(Family description, key to genera by L.T. Dempster)
Perennial, subshrub from caudex or rhizome, glabrous to tomentose
Stem very short to high-climbing, generally twisting and twining
Leaf generally > 1 cm, linear to reniform, often sagittate to hastate, rarely deeply divided
Inflorescence: peduncle generally 1-flowered; bractlets small and remote from calyx to large and concealing calyx, sometimes lobed
Flower generally showy; corolla glabrous, white or yellow to pink or purple; ovary chamber 1 (septa generally incomplete), stigma lobes 2, generally swollen, cylindric or oblong, ± flattened
Fruit ± spheric, ± inflated
Seeds generally ± 4
Species in genus: ± 25 species: temp, worldwide
Etymology: (Greek: concealing calyx, from bractlets of some)
Reference: [Brummitt 1980 Kew Bull 35(2):327328]
Intergradation common; intermediate forms often difficult to identify. Appears similar to Convolvulus , but anatomy suggests that the 2 genera are not very closely related.
Perennial from rhizome, densely shaggy-tomentose
Stem decumbent to ascending, 10100 cm, not or barely climbing
Leaf < 6 cm, < 9 cm wide (generally much smaller), narrowly triangular to ± reniform; lobes 12-tipped; margin not wavy; tip notched to acute
Inflorescence: peduncle 69 cm, < or > subtending leaf; bractlets 720 mm, 515 mm wide, entire, lanceolate to widely ovate, generally acute, generally attached just below calyx and ± concealing it
Flower: sepals 915 mm, ± densely hairy; corolla 2045 mm, white
Ecology: Dry slopes, chaparral
Elevation: 3003500 m.
Bioregional distribution: Cascade Range, Sierra Nevada, San Francisco Bay Area, South Coast Ranges, Western Transverse Ranges
Synonyms: Convolvulus m. Greene
Plant hairs generally brown or golden-brown (grayish)
Leaf 36 cm, 49 cm wide, widely triangular to ± reniform; lobes generally 2-tipped; tip notched to acute
Inflorescence: peduncle 35 cm, < subtending leaf
Ecology: Habitat of sp.
Elevation: generally 10002400 m.
Bioregional distribution: Cascade Range, Sierra Nevada. Intergrades with C. occidentalis and perhaps C. collina subsp. tridactylosa. Plants with bractlets attached well below calyx from s SN may be called var. berryi (Eastw.) Brummitt [Berry's morning-glory; UNCOMMON]
