Names
Cassipourea gummiflua Tul. [family RHIZOPHORACEAE], in Ann. Sci. Nat., sér. 4, 6: 123 (1856); Alston in K.B. 1925: 272 (1925); J. Lewis in K.B. 1955: 147 (1955). Type: Madagascar, Nossi-bé Island, Boivin (P, holo.!, K,? iso.!)
Information
Tree or shrub up to 25 m. tall; young stem very shortly appressed-pubescent, glabrescent (one-year-old stem glabrous). Leaves petiolate, petiole 6–15 mm. long, glabrous; blade varying from narrowly elliptic to almost broadly oblong and elliptic-lanceolate to broadly elliptic, up to 11.5 × 6 cm. or 14 × 5 cm., rounded or cuneate to an acute base, rounded to acuminate or very rarely cuneate to an obtuse or acute apex, margin entire or shallowly sinuate or bluntly and shallowly serrate especially above, glabrous. Flowers numerous; pedicels 1.5–4 mm. long, glabrous, articulate medially or above. Calyx 4–5 or 5–6 (rarely 7 [–8])-fid; tube 2–3 mm. long, lobes 1 mm. long, semi-circular to deltoid, apex obtuse (to acute), glabrous. Stamens 8–10 or 10–12 (–14), inserted on the ± lobed disc. Ovary superior to partly inferior, very usually 2-celled (very rarely 3-celled), glabrous, ± sparsely pilose above the middle, to regularly pubescent or densely white-hirsute especially above the middle. Capsule ellipsoid or subspherical to obovoid, up to 7 mm. long, glabrous or shortly pubescent.

Notes
VARIATION. The characters of variational interest in the species as a whole are the ovary indumentum, the pedicel length, and the shape of the leaves, especially the last two. Collectors should try to assess and preserve the variation of these characters within local populations. Two varieties of this species occur in our area; their diagnostic features are italicized in the descriptions below. As accepted by the present author, C. gummiflua Tul. is a very variable and wide-ranging species, the full treatment of which remains to be worked out. In the present arrangement the type variety is found only in Madagascar, and the fourth variant is var. mannii (Hook. f. ex Oliv.) J. Lewis from West Africa. There is an urgent need for specimens showing stages in the development of the flowers and fruits, especially for the latter.
