those of M. fulgens are three times as long. This is also allied to MZ. Aentii, H. f. & 
Th., the ovaries of which have, however, never more than two ovules.

upper surface olivaceous when dry, glabrous, shining; the lower glaucous, slightly 
puberulous when young; main nerves 10 to 12 pairs, spreading, very indistinct; length 
2°5 to 4 in., breadth 1°25 to 18 in.; petiole *35 in. Flowers +3 to °65 in. long, axillary, 
solitary or in pairs; pedicels rather stout, deflexed, rufous-puberulous, bi-bracteolate 
ut the base, °25 to *35 in. long. Sepals broadly ovate, acute, concave, connate into a 
triangular cup, rufous-puberulous outside, glabrous inside, persistent. Petals thick; the 
outer flat, oblong-ovate, acute, minutely silky, rufous-tomentose outside, hoary pubescent 
inside, except on the glabrous basal excavation, °3 to 65 in. long ; inner petals less than 
half as long, with a large glabrous basal concavity and a short, thick, triquetrous point, 
hoary-puberulous. Stamens numerous, filament very short; apical process of connective 
orbicular. Ovaries narrowly oblong, glabrous, pitted, 2-ovuled ; style lateral, nearly as

Only two species of Melodorum besides this have glabrous ovaries (M. Kentii and 
M. elegans); but whereas those of this and M. Kentii are 2-ovuled, the ovaries of 
M. elegans have 8, or, according to Sir Joseph Hooker, sometimes 10 ovules. This 
species has, however, different leaves from the two above mentioned, and its carpels are 
much smaller and quite globular. In this, as in other species of Melodorum, there is 
considerable variability in the size of the flowers.
