Morphology Reproductive morphology Flowers

Calyx spathaceous (1- lobed), chartaceous, glabrous at the base on inner face, and villose to lanate at the apex; petals 5, pink to lilac, claw 0.5 - 1.1 x 0.6 - 0.9 mm, blade 6.6 - 7.7 x 4.6 - 5.4 mm, vexillum orbicular, the others elliptic; stamens 8- 11, filaments 1.2- 1.9 x 0.5 mm, glabrous, anthers 3.9 - 6.1 x 0.4 - 0.6 mm, subulate, apex mucronate, sparsely pilose; gynoecium with stipe 1.6 - 2.4 mm long, sericeous, ovary 4 - 5.2 x 1.5 - 2.5 mm, symmetric, elliptic, sericeous, c. 7- 10 ovulate, style 1.8 punctiform, glabrous

Morphology Reproductive morphology Fruits

Fruit globose, 1.6 - 2.5 x 0.9 - 1.5 cm when mature, seed oblong.

Distribution

Zollernia glabra is restricted to the Atlantic coastal zone from the state of Bahia to the north of São Paulo

Ecology

According to Mansano & Tozzi (1999b), is a species of the Atlantic Rain Forest (Floresta Pluvial Tropical Atlântica)

Phenology

Flowering from December to April, collected in fruit in September.

Note

Zollernia glabra is characterised by having racemes in terminal fascicles or panicles. It differs from Z. ilicifolia in having flexible stipules, leaves without an evident marginal vein, generally entire leaf margins and inflorescences exclusively terminal (vs. stipules rigid, leaves with marginal veins evident and generally with serrate margins, and the inflorescences axillary and terminal).
