Inflorescence: cyme or flowers 1 in axils; bracts subtending flowers 0 or 2. Flower: bisexual, radial; sepals (4)5, +- free, overlapping, persistent, often unequal; corolla generally showy, generally bell-shaped, +- shallowly 5-lobed, generally pleated and twisted in bud; stamens 5, epipetalous; pistil 1, ovary superior, chambers generally 2, each generally 2-ovuled, styles 1--2.

Common Name: MORNING-GLORY Habit: Perennial herb, subshrub from caudex or rhizome, glabrous to tomentose. Stem: short to high-climbing, generally twisting, twining. Leaf: generally > 1 cm, linear to reniform or sagittate to hastate (deeply divided). Inflorescence: peduncle generally 1-flowered; bracts generally +- opposite, lobed or not, > 1 mm below calyx, not hiding it, small, to < 1 mm below calyx, hiding it or +- so, large. Flower: generally showy; corolla glabrous, white or yellow to pink or purple; ovary chamber 1, style 1, stigma lobes 2, oblong, tips obtuse. Fruit: +- spheric, +- inflated. Seed: generally +- 4. Etymology: (Greek: hiding calyx, by bracts of some) Note: Intermediates common, often difficult to identify. Molecular evidence indicates close relationship with Convolvulus (Carine et al. 2004 Amer J Bot 91:1070--1085). Bracts qualify as bractlets by some definitions. Leaf blade length measured along midrib. eFlora Treatment Author: R.K. Brummitt Reference: Brummitt 2002 Madroño 49:130--131 Unabridged Reference: Brummitt 1980 Kew Bull 35(2):327--328
Calystegia atriplicifolia Hallier f. subsp. buttensis Brummitt
NATIVE Habit: Perennial herb from rhizome, generally glabrous. Stem: decumbent to +- erect, 10--50 cm. Leaf: blade generally 2--4 cm, generally triangular-hastate to reniform; lobes not clearly defined, directed +- laterally, truncate to wedge-shaped or widely rounded, occasionally with shallow sinus. Inflorescence: peduncle < 5 cm, generally < subtending leaf; bracts not fully hiding calyx, 8--12 mm, 3--9 mm wide, +- cordate-elliptic, entire, +- obtuse. Flower: sepals 10--15 mm; corolla 30--45 mm, white (pink-tinged). Ecology: Dry, rocky places in open forest, chaparral; Elevation: 600--1200 m. Bioregional Distribution: KR, CaRH, SnFrB. Flowering Time: May--Jul Note: Scattered, uncommon, variable; intergrades with Calystegia occidentalis subsp. occidentalis. Plants intermediate to Calystegia atriplicifolia subsp. atriplicifolia of Oregon, Washington, in KR; plants +- intermediate to Calystegia subacaulis in SnFrB. Synonyms: Convolvulus nyctagineus Greene, in part Unabridged Note:Calystegia atriplicifolia subsp. atriplicifolia of Oregon & Washington differs by leaf blades generally 4--6 cm, more rounded, less hastate; bracts generally 15--22 mm; corolla generally 50--70 mm.
