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

MAP CONTROLS 1. You can change the display of the base map layer control box in the upper right-hand corner.
2. County and Jepson Region polygons can be turned off and on using the check boxes.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
