Petiole, obscure, more or less winged, up to 0.6 cm long; lamina variable, (lanceolate to) elliptical to broadly ovate, widest in or below the middle, 7-14 by (1.8-3-8- (12) cm, dull on both sides or shining above, contracted at the base, usually recurved at the margin, rounded or obtuse at the apex; venation distinctly reticulate on both sides. Inflorescences solitary or few in the axils; axis bearing 1-3 decussate subumbellate pairs of triads or single flowers, 3-1l-(15) mm long; peduncles of the triads or single flowers 3-6 mm long; pedicels of the lateral flowers of the triads (when present) 2-3 mm long; bracts acute, spreading, 1 5 mm long. Calyx campanulate to narrow cylindrical, 3-5 mm long; limb undulate, 05 mm long. Corolla in the mature bud robust, inflated at the base to about twice the width of the calyx, not distinctly clavate, obtuse or rounded at the apex, 45-60 mm long; petals in the open flower united to about the middle. Anthers 6-8 mm long, about equal to the free parts of the filaments. Style articulate c. 1 mm above the base, persistent on the fruit; stigma globose, 3 times as wide as the style. Fruit ellipsoidal.

Occurrence. New Caledonia, Isle of Pines and the Loyalty Islands (Fig. 3), mostly 250 to 800 m altitude.

Representative Specimens. See citations of type specimens above.

Several authors have reported that this plant is able to grow independently in the soil before making haustorial attachments to the aerial parts of the host. For further discussion, see note under Amyema scandens subsp. scandens.

Amylotheca pyramidata is very similar to A. dictyophleba, differing primarily in the larger dimensions of the parts and in the inflated corolla base.
