Description
|
Small trees or shrubs (or subherbaceous perennials when young) of higher elevations, the branchlets thick, coarse, often gnarled, pithy and weak; leaves simple, large, usually lobate and dentate but in some species subentire, several- ranked, usually conspicuously lighter below than above, pinnately nerved, reticu- late, varying considerably according to position on the plant; inflorescence a large, graceful panicle, terminal, subterminal, or lateral from the branchlets; bracts and bractlets small and narrow, frequently caducous; pedicels slender; flowers numer- ous, apetalous, whitish; sepals 2, usually oblong or elliptic, concave, sessile; stamens few to many, invested by the sepals, the anthers slender, the filaments short; ovary fusiform, stipitate, bearing a single basifixed ovule; style slender; stigma bilamellate, extended beyond the sepals and stamens, very conspicuous; fruit somewhat fleshy, dehiscing by 2 lateral valves opening first from the base, the replum persistent after dehiscence and fall of the seed; the single seed conspicuously arillate basally.

New World tropics and subtropics.

Note
|
The genus is unusual in the family in not being herbaceous and in having apetalous flowers and a 1-seeded fruit. It must be considered as somewhat atypical of the Papaveraceae. As here interpreted a single species occurs in Panama.
