Higher Taxonomy
Family: ConvolvulaceaeView DescriptionDichotomous Key

Common Name: MORNING-GLORY FAMILY
Habit: Annual, perennial herb, subshrub, generally twining or trailing. Leaf: 0 or alternate. 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. Fruit: generally capsule. Seed: 1--4(6).
Genera In Family: 55--60 genera, 1600--1700 species: warm temperate to tropics; some cultivated for food or as ornamental (Ipomoea). Note: Monophyletic only if Cuscutaceae included, as treated here. Ipomoea cairica (L.) Sweet, Ipomoea hederacea Jacq. [Ipomoea nil L., misappl.], Ipomoea indica (Burm.) Merr. (including Ipomoea mutabilis Ker Gawl.), Ipomoea purpurea (L.)

Common Name: DODDER
Habit: Vine, annual (perennial herb if on perennial host), not in contact with ground, attached to, holoparasitic on host by many small, specialized roots (haustoria) along stem, generally glabrous. Stem: thread-like, +- green, yellow, orange, or +- red. Leaf: 0 or scale-like, alternate, +- 2 mm. Inflorescence: generally cyme, head- to panicle-like (flowers 1), subtended by 0--3 bracts. Flower: bisexual, radial, parts generally in 4s or 5s; calyx generally divided 2/5--3/5, persistent generally +- cream-white; corolla generally +- white, persistent (withered in fruit) or not, tube cup-shaped to cylindric, bulged or horizontally ridged below lobes or generally not, generally with scales subtending stamens, lobes alternate stamens, erect to reflexed; ovary superior, chambers 2, each 2-ovuled, styles 2, generally free, persistent, stigmas 2, generally spheric, persistent. Fruit: capsule, generally indehiscent to irregularly dehiscent (or circumscissile near base), spheric to ovoid, depressed or not, thickened and/or raised around generally inconspicuous opening between styles or not. Seed: 1--4; coat papillate when hydrated, honeycombed when dry, (rarely neither, with cells +- rectangular, in +- jigsaw-puzzle-like arrangement); embryo generally slender, 1--3-coiled.
Species In Genus: +- 180 species: cosmopolitan, especially warmer regions of western hemisphere and Polynesia. Etymology: (Aramaic, Hebrew; from the verb K-S-Y (Kaph, Shin, Yodh), to cover, from habit) Note: By persistent, withered corolla, fruit may be "capped" (corolla on top of fruit), "surrounded" (fruit at least in part visible, corolla +- loosely around fruit), or "enclosed" (fruit not visible, corolla +- tightly around fruit). Cuscuta pentagona Engelm. excluded.
