Names
MERREMIA Dennst. [family CONVOLVULACEAE], Hallier f. in Engl. Jahrb. xvi. 581 (incl. Operculina).
Information
Sepals 5, generally subequal, and more or less coriaceous, elliptic or lanceolate, more rarely orbicular, accrescent in the larger species. Corolla campanulate to broadly infundibuliform, often white, sometimes yellowish; midpetaline areas generally not well defined. Anthers usually twisted above. Pollen not spiny. Ovary 2–4-celled, 4-ovuled; style and stigma of Ipomœa. Capsule with generally valvular, rarely transverse dehiscence. Seeds generally 4, glabrous. —Annual or perennial plants, with generally herbaceous climbing, more rarely prostrate or trailing stems and axillary flowers, solitary or in few- to many-flowered dichasial cymes.
Range
Species about 60, widely spread in the tropics.
Notes
I cannot distinguish generically the larger-flowered and fruited species which have been regarded as forming a distinct genus Operculina. The transverse dehishiscence of the fruit is not general in this small group; in one of its most typical members, I. kentrocaulos, the large capsule splits longitudinally, the valves separating from the central septum, which bears the remains of the style.
