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.) Roth, Ipomoea triloba L., all included in TJM (1993), not naturalized.

Genus: CuscutaView DescriptionDichotomous Key

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.

Cuscuta subinclusa Durand & Hilg.
NATIVE
Inflorescence: +- head-like, flowers 5--20(45); pedicels 0--1 mm. Flower: 5--7(9) mm, generally membranous, parts in 5s; calyx generally 1/2 corolla tube, bell-shaped, divided 3/5--2/3, finely veined, shiny, lobes widely ovate to lanceolate, bases overlapped, margins entire, tip acute (abruptly pointed); corolla tube 2.5--3.5(4.5) mm, cylindric, generally horizontally ridged below lobes, scales +- 1/2 corolla tube, oblong to spoon-shaped, rounded, irregularly short-fringed, lobes spreading to reflexed, 1/4--1/3 tube, ovate-triangular, papillate, margins entire, tip acute to +- acuminate, straight; filaments 0--0.1 mm, anthers included to +- exserted, 0.8--2 mm, linear; styles 1--1.5 mm. Fruit: 1.5--3 mm, 1.2--2.5 mm wide, +- ovoid, thickened, raised around opening between styles, not translucent, capped by corolla. Seed: 1, 1.3--1.7 mm, 1.2--1.5 mm wide, +- spheric to widely ovoid.
Ecology: Generally on herbs, shrubs, in forests near streams, river canyon bottoms, salt marshes; Elevation: < 2000 m. Bioregional Distribution: NCoR, SN, GV, SnFrB, SCoR, SCo, SnJt, GB; Distribution Outside California: Oregon, Baja California. Flowering Time: Mar--Oct(Dec?)
Unabridged Note: Cuscuta subinclusa Durand & Hilg. (Nov 1854) was published +- 1 month earlier than Cuscuta ceanothi Behr (Dec 1854), so that it would have priority if the two names were considered to represent a single taxon; however, the protologue of Cuscuta ceanothi departs from that of Cuscuta subinclusa in some respects and offers no information regarding a type, so that neotypification will be required to firmly establish the application of Cuscuta ceanothi, which in fact might represent a distinct taxon.
