or petiolate, membranaceous or coriaceous. Stipules interpetiolar, deciduous. Flowers sessile, large or 
small, bracteolate or ebracteolate, secund on the branches of axillary forked pedunculate cymes, often 
dichotomously branched with a flower between the contracted branches, or rarely one-flowered. Bracts 
and bractlets lanceolate, acute, minute, deciduous. Calyx ovoid or globose, the limb produced above 
the ovary into a cup-shaped or elongated tube, irregularly two to four or regularly four to nine-toothed,

naked in the throat, the limb four to nine-lobed, with oblong acute or rounded lobes. Stamens four to 
nine, inserted in the tube of the corolla, alternate with its lobes, included ; filaments short or wanting ; 
anthers oblong-linear, attached on the back, introrse, two-celled, the cells opening longitudinally. Disk 
epigynous. Ovary four to nine-celled, the cells elongated, tubular; style stout or filiform; stigma 
subcapitate or minutely two-lobed; ovules solitary, suspended on the thickened funicle from the inner 
angle of the cell, anatropous ; raphe ventral; micropyle superior. Drupe globose or obtusely angled, 
or rarely ovoid; sarcocarp thin and fleshy; putamen osseous or ligneous, globose, obtusely angled or 
sulcate, four to nine-celled, the cells narrow and often curved upward. Seed compressed, suspended 
on the thick funicle closing the orifice of the wall of the stone, straight or excurved ; testa membrana- 
ceous ; albumen fleshy, thin or wanting. Embryo elongated, cylindrical or compressed; cotyledons 
flat, minute, not longer than the elongated terete radicle turned towards the hilum. 
Guettarda is represented by about fifty species, mostly confined to the tropical regions of America,! 
where they are found from southern Florida to Mexico, Central America,’ Brazil,? and Peru,‘ although 
one species ° is widely distributed on the maritime shores from eastern tropical Africa to Australia and
