Read about Odontadenia macrantha in the Standard Cyclopedia of Horticulture

Odontadenia grandiflora, Schum. (0. speciosa, Benth. Dipladenia Harrisii, Hook.). Shrubby branched climber: largest Lvs. 10-15 x 4-5 in., oblong, tapering, scarcely leathery, feather-veined, often purplish beneath; petioles stout, scarcely 1 in. long: racemes axillary and terminal; pedicels red, often 1 in. long, curved downward; corolla- tube with a roundish base about ½ in. long and thick, then suddenly constricted, then gradually widening into a funnel-shaped fl. Brazil, Guiana, Trinidad. B.M. 4825.—The fls. are fragrant, about 3 in. across, funnel- shaped, with 5 rounded, spreading lobes, and are more or less streaked with red in the throat, at the base of the lobes, and on the back of the tube. The treatment for dipladenias (see Dipladenia, Vol. II) should be attempted for Odontadenia, but O. grandiflora perhaps grows at lower altitudes, and may require the treatment usually given to hothouse vines.
