CONVOLVULACEAE MORNING-GLORY FAMILY

Robert E. Preston, except as noted

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).
55–60 genera, 1600–1700 species: warm temperate to tropics; some cultivated for food or as ornamental (Ipomoea). [Stefanovic et al. 2003 Syst Bot 28:791–806] 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. —Scientific Editor: Thomas J. Rosatti.

CALYSTEGIA MORNING-GLORY

R.K. Brummitt

Perennial, 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, swollen.
Fruit: ± spheric, ± inflated.
Seed: generally ± 4.
± 25 species: temperate, worldwide. (Greek: hiding calyx, by bracts of some) [Brummitt 2002 Madroño 49:130–131] 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. Lf blade length measured along midrib.

Key to Calystegia

C. macrostegia (Greene) Brummitt
NATIVE
Perennial, subshrub from woody caudex, glabrous to densely short-hairy.
Stem: slender, weakly climbing to woody, or strongly climbing, 1–9 m.
Leaf: < 13 cm, generally widely triangular, lobed.
Inflorescence: peduncle 1- to several-flowered, generally > subtending leaf; bracts ± hiding calyx, 6–37 mm, 4–30 mm wide, lanceolate to ± round, entire, flat to sac-like.
Flower: sepals 7–25 mm; corolla 22–68 mm, white or fading pink. [Online Interchange]

C. macrostegia subsp. arida (Greene) Brummitt
NATIVE
Plant hairy.
Stem: slender, trailing or weakly climbing.
Leaf: lobes 1-tipped; sinus rounded to square.
Inflorescence: bracts 10–21 mm, 6–10 mm wide, lanceolate, not or ± keeled, tip acute.
Flower: sepals 9–12 mm; corolla 24–34 mm.
Coastal scrub, chaparral; < 1000 m. San Gabriel Mountains, San Bernardino Mountains, n Peninsular Ranges. Intergrades with Calystegia macrostegia subsp. intermedia, Calystegia macrostegia subsp. tenuifolia, Calystegia occidentalis subsp. fulcrata, probably Calystegia peirsonii. May–Jun [Online Interchange]
Unabridged note: There are Consortium records that, if verified, would voucher elevations up to 1478 m.
