- Description
- Ipomoea saintronanensis is a deciduous woody climber. It has twining stems that are hairless or loosely covered with long hairs. The leaves are broadly ovate to almost circular, 5 -21cm long by 5-21cm broad, with a short pointed tip (shortly acuminate) and a heart-shaped (cordate) base, becoming hairless above and softly hairy beneath. The leaf stalks (petioles) are 3-14cm long.
The flowers occur where the leaf stalk joins the stem (axillary), on stalks (peduncles) 10-90mm long and bearing one flower. The flower forms a slender tube that expands abruptly into a flat or saucer-shaped limb. The sepals (flower bracts) are ovate to orbicular, hairy, and 25-35 mm long.The flowers are white to pale pink in colour, 8-12cm long and with silky mid-petal bands. The flowers contain 5 stamens, each 9-13cm long and attached 2-3cm above the base on the inside of the tube. The seed capsules are globular, hairless, 17mm long and have two chambers. The pods contain 4 seeds that are densely covered with long wavy hairs to 15mm long.
This species is related to I. macrantha but differs in the hairy sepals and seeds. I. macrantha is, however, a coast species and the distributions do not overlap. (Johnson 1986) - Distribution
- Ipomoea saintronanensis is found south-west of Mt Garnet, in north-east Queensland. (Johnson 1986; Herbrecs 2008)
