Description.

Twining perennial herb to 3 m, stems glabrous, often muricate. Leaves petiolate, digitately divided into 5-7 leaflets, the laterals sometimes joined at base, leaflets 1-5 × 0.3-1 cm, lanceolate or oblong-lanceolate, acute and mucronate, glabrous; petioles with stipule-like outgrowths at base, 1-5 cm. Flowers usually solitary, sometimes in shortly pedunculate, 2-3-flowered axillary cymes; peduncles 0.3-1 cm; bracteoles 1-2 mm, oblong, caducous; pedicels 0.3-2.5 cm; sepals slightly unequal, glabrous with scarious margins, outer 5-7 × 4 mm oblong-ovate, acute, often abaxially rugose, inner 6-8 mm, broadly ovate-elliptic, obtuse; corolla 4.5-7 cm long, funnel-shaped, pink, glabrous, limb 4 cm diam., unlobed. Capsules 1-1.3 cm, subglobose, glabrous; seeds 5-6 mm, tomentellous with longer caducous marginal hairs, rarely subglabrous.

Distribution.

A species of Old World origin, now widespread throughout tropical and subtropical regions up to least 2600 m, but much more common in some regions than others, such as northern Argentina, eastern Paraguay and southern Brazil; unexpectedly absent in others, such as Hispaniola (Liogier 1994). It is well naturalised in waste places, usually near settlements but is also cultivated so occurring in and around gardens.

Notes.

Readily identified by the 5-7-foliolate leaves and the nearly unique, stipule-like outgrowths at the base of the petiole. It is, however, extremely variable, especially so in Hawaii. Many plants from Hawaii have elliptic leaflets up to 3.5 cm wide and correspondingly robust pseudo-stipules. There also occurs in Hawaii a var. lineariloba with very long narrow elliptic leaflets, Rock s.n. (K) being a good example of this variety. Var. hederifolia with lobed leaves, in which the leaflets are partially fused is also present in Hawaii. It is one of a number of recognised Old World varieties.

We have found a specimen (W.G. Herter 99285 from Miguelete near Montevideo in Uruguay) at S labelled as an isotype of Ipomoea cairica forma obscura but have been unable to trace the publication of this name.

••• Species 393-419 This is the large, essentially Old World Clade (OWC), containing a small number of naturally occurring New World species as well as several Old World species which are ancient or recent introductions to the New World.
