Description

Aerial stem-parasitic shrubs. Leaves verticillate; venation pinnate. Inflorescencess axillary, a subumbellate, subcapitate raceme of spirally arranged dichasia (triads) crowded towards the apex of the axis and subtended by an involucre formed from the enlarged central bracts of the outermost triads; bracts single under each flower.

Distribution

Asia-Tropical: Borneo (Sabah present)
One species confined to Borneo (Sabah).

Morphology

The inflorescence is an axillary raceme of shortly pedunculate triads apparently crowded into a tight spiral towards the apex of the axis, although they may actually be in several oblique, many-flowered whorls condensed close together. The bracts are decurrent to the bases of the peduncles of the triads, those of the outer (lowermost) triads being longer and wider, with margins free from the peduncles, and together forming a short imbricate involucre subtending the flowers.

Taxonomy

The genus is closely related to Decaisnina, differing primarily in the gamopetalous corolla. For further discussion see
