  • Description

    Species Description - Racemose inflorescences 2-7 cm long, just as long as in var. pubiflora. Flowers yellow or white. Petals 3.25-5 mm long, slightly narrower than is usual in var. pubiflora. Seeds 5-8 mm diam., glabrous.

  • Discussion

    Fo. grandifolia differs from var. pubiflora as well as from fo. andersonii by its glabrous seeds (versus seeds puberulous to pilosulous). Fo. grandifolia is more heterogeneous than fo. andersonii and seems to be composed of regional populations: (1) Amazonia: Specimens with leaves relatively larger and longer acuminate than is usual for var. pubiflora; they resemble those of the regional populations of fo. andersonii; capsules and seeds of Amazonian specimens of fo. grandifolia much resemble those of R. campto-neura; (2) Venezuela: Specimens with leaves as large as in specimens belonging to the regional populations of var. pubiflora, the subcoriaceous leaves and the capsules much resemble those of the regional population of R. ovalifolia; and (3) Central America: Specimens with leaves relatively smaller and more serrate and crenate than usual for var. pubiflora, and therefore resembling those of R. squamata; also the indument of the capsule and the glabrous seeds much resemble those of R. squamata.

    Capsules of fo. grandifolia can be distinguished from those of the similar species by the presence of subpersistent floral parts, such as sepals, petals, reduced stamens or staminodes versus them wanting. The inflorescences of specimens of fo. grandifolia collected in Venezuela, Colombia and Central America are usually more densiflorous than those collected in Amazonia. Concerning the Venezuelan specimens, it is not surprising that some of them can be easily confused with those of R. ovalifolia, which occurs along the Río Orinoco. Outside this region both taxa can be more clearly distinguished from each other. Introgressive hybridization with R. ovalifolia is supposed.

    Distribution and Ecology: Probably flowering and fruiting throughout the year. The ecological amplitude is similar to that of var. pubiflora, but it is also recorded from igneous outcrops in Venezuela, from 0 to 600 m. The main area of distribution is in West and Upper Amazonia (SE Colombia, S Venezuela, N Peru and NW Brazil), including the forest refugia Ventuari, Tefe, Loreto, and Ucayali. This forma also occurs disjunctly in some forest refugia of the Andean region and adjacent Panama: (a) NW Colombia, W of the eastern Darien
