description
Ipomoea ochracea is a slightly woody, twisting liana that is up to 5 m in length and forms only a little watery milky sap. The stems are cylindrical, slender and hairy. The leaves are alternate. The leaf blades are simple, 3 to 10 cm long and 2.5 to 7.5 cm wide. They are egg-shaped, membranous and hairless apart from a few trichomes along the vein. Towards the front they are pointed and usually prickly, the base is heart-shaped. The leaf margin is whole or curved. The veins protrude slightly on the top and bottom, the bottom is usually bluish frosted. The leaf stalks are 2 to 6 cm long and hairy.
The flowers stand individually or in double-forked inflorescences in the armpits. The peduncle is slightly longer than the pedicels . The bracts are egg-shaped and about 1.6 cm long. The calyx is green, does not enlarge and consists of five almost equally large, egg-shaped or elongated-egg-shaped, hairless, dotted sepals with a length of 5 to 7 cm. The crown is funnel-shaped, pale yellow and purple in color at the base of the corolla tube. It becomes 3 to 4 cm long and has five weak, rounded lobes. The stamens and the stigma are white and protrude beyond the crown.
The fruit is an egg-shaped, 1.3 to 1.6 cm long, straw-yellow capsule with a thin pericarp . The calyx is permanent on the fruit. Four seeds are formed per fruit , these are 4 to 5 mm long, black, dull and hairless.
