Author: (Carl(Karl) Friedrich Philipp von Martius (1794-1868) ex Jacques Denys Choisy (1799-1859)) Daniel Frank Austin (1943-2015)Family: Convolvulaceae Tribe: Ipomoeeae
Genus: Ipomoea
Synonym(s): Ipomoea fistulosa
English name: Pink Morning Glory
Zone: Chile
Description
This subspecies is probably native in swamp and flooded pampas in eastern Bolivia, northern Argentina (Formosa, Corrientes), Eastern Paraguay and southern Brazil in the Pantanal and Rio Paraguay-Parana systems but also possibly so in seasonally dry swampy areas elsewhere. It is apparently rare or absent in the Amazon forest region, not being recorded from Pando in Bolivia or Rôndonia in Brazil and with few records from Brazilian Amazonas. It is also widely cultivated as an ornamental in gardens up to at least 1000m and it is not always easy to decide whether a population is spontaneous or planted. It seems that all collections from the Caribbean, the United States and probably Mexico are cultivated or recently naturalized plants.
Botanical Description
This species is an erect undershrub to 4m, often growing in clumps, stems stout, hollow, canescent when young, becoming glabrous.
The leaves are petiolate, 8-20 x 3-10cm, elongate, base cordate to subtruncate with rounded auricles, apex long-acuminate, both surfaces grey-canescent when young, glabrescent, veins prominent abaxially. The petioles are 3-8cm.
The inflorescence is of long-pedunculate axillary, somewhat compact cymes. The peduncles are 2-12cm. The bracteoles are 3-4mm, ovate or elliptic, caducous. The secondary peduncles are 3-7mm. The pedicels are 5-15mm, puberulent. The sepals are subequal, 5-6 x 7-8mm, ovate to suborbicular, rounded, tomentellous, margins scarious. The corolla is 6-7cm long, funnel-shaped, pink, tomentellous in bud, labrescent, limb 4.5-5cm in diameter, shallowly lobed.
The capsules are 18 x 10mm, ellipsoid, glabrous. The seeds are 10-11 x 3-4mm, woolly with very long hairs on the angles.
