Type

Type: Colombia, Norte de Santander, J. Cuatrecasas 13321 (holotype LIL!, isotype F).

Morphology General Habit

Weak liana to 3 m, stems woody, glabrous to minutely scabridulous, dotted with black glands

Morphology Leaves

Leaves petiolate, 4 – 9 × 3 – 6 cm, ovate to suborbicular, cordate with rounded auricles, shortly acuminate, usually glabrous but sometimes scabridulous-puberulent, abaxially often minutely black-punctate; petioles 2.5 – 5 cm, scabridulous

Morphology Reproductive morphology Inflorescences

Inflorescence of pedunculate axillary cymes, these often developing into a raceme or panicle like structure 5 – 10 cm long; peduncles 1 – 4.5 cm, sometimes extended into a rhachis up to 3 cm long; secondary peduncles 0.5 – 1.8 cm long; bracteoles scale-like, caducous; pedicels very variable in length 5 – 15 mm long, glabrous; sepals subequal, 5 – 7 × 3 – 5 mm, elliptic, obtuse, scarious-margined, inner obovate with very broad scarious margins; corolla 2.3 – 3.5 cm, creamy-white with greenish midpetaline bands and (sometimes a dull violet centre), campanulate, glabrous, limb 2.5 cm diam., undulate; stamens held at corolla mouth

Morphology Reproductive morphology Fruits

Capsule ovoid, 10 – 12 × 7 – 8 mm, glabrous; seeds 5 mm long, pilose

Ecology

Widely distributed in tropical America from southern Mexico south to Bolivia and Paraguay but usually in rainforest or in moister areas of seasonally dry forest. In Bolivia it is principally a plant of the Andean foothills of the Amboró and Carrasco National Parks but is also common in Chiquitano Dry Forest. Map 12.

Conservation

Least Concern (LC).

Note

Flowers principally in April and May

Usually easily identified by the small flattish sepals and short, campanulate, cream corolla but sometimes difficult to distinguish herbarium specimens from Ipomoea batatoides which also commonly has leaves abaxially gland-dotted. However in I. batatoides the corolla is much larger and usually pink and the sepals are coriaceous and concave, without broad scarious margins. It is similar in flower colour and tendency to produce raceme-like inflorescences to I. corymbosa but for differences with that species see under I. corymbosa.In southern Brazil Ipomoea reticulata is largely replaced by I. saopaulista O’Donell, which differs in its larger corollas. Intermediates between the two are reported from Goiás.
