Type
Suriname, distrito Brokopondo, Natuurpark Brownsberg, 13 Oct. 1972 (fl), L.B.B. (=Lands Bosbeheer Suriname) 14654 (NY!, holotypus; U 0018203!, isotypus).
Morphology General Habit
Tree 10 - 15 m tall

Stipules 1.8 - 3.8 x 0.7 - 1.2 mm, linear to triangular, glabrous, ciliate to pilose; petiole 6.2 - 11.2 mm long, glabrous; leaf blade 10.7- 17.5 x 5.2 - 7.1 cm, chartaceous, elliptic, base cuneate, apex acute to acuminate, glabrous, venation prominent beneath, margin serrate
Morphology Reproductive morphology Inflorescences
Panicle, c. 14.3 cm long, terminal, axis c. 1.8 mm diam., generally fulvous- tomentose; bracts 1.3- 1.9 x 0.5- 1 mm, triangular, ciliate; bracteoles c. 1 x 0.3 - 0.5 mm, triangular, ciliate, attached halfway up the pedicel; pedicel 6.2 - 10.2 x 0.9 mm, fulvous-tomentose; buds 7.8 - 9.7 x 2.5 - 3 mm, lanceolate-asymmetric, base acute, apex acuminate, tomentose
Morphology Reproductive morphology Flowers
Calyx spathaceous, 1-lobed, inner surface glabrous at the base and pilose at the apex; petals 5, claws 1.6 - 2.2 x 0.8 - 1.3 mm, blades 6.1 - 8.5 x 3.2 - 7.5 mm, elliptic; stamens 10, filaments 2.5 - 3.1 x 0.2 - 0.4 mm, glabrous, anthers 5.9 - 6.5 x 0.9 mm, linear-lanceolate, pilose; gynoecium stipe c. 1.3 - 1.8 mm long, sparsely sericeous, ovary 4.2 - 5.5 x 1.5 - 1.8 mm, sericeous, 8-ovulate, style 4.1 - 5.2 mm long, slightly incurved or straight, glabrous, stigma punctiform, glabrous.
Ecology
In seasonally dry forests ("Floresta Estacional")
Distribution
Suriname and French Guiana, which have a short dry season.
Phenology
Collected in flower in October.
Note
This species is very similar vegetatively to Zollernia grandifolia, but differs in having a hairy gynoecium. (Z. grandifolia is the only species of Zollernia with a glabrous gynoecium). Z. surinamensis differs from Zollernia paraensis in the persistent stipules and from Z. kanukuensis in the petal-blade being longer than wide.
