CLUSIACEAE

2. CARAIPA Aubl., Hist. Pl. Guiane 561, t. 223. 1775.

by Klaus Kubitzki and Bruce K. Holst

Trees or shrubs; latex glands present; indument principally of stellate hairs. Leaves alternate, secondary veins distant, tertiaries often parallel; petioles relatively short. Inflorescences terminal or axillary panicles or racemes. Flowers bisexual, fragrant. Sepals 5, quincuncial, slightly connate at base; petals contorted, yellow or whitish. Stamens numerous, persistent after flowering; filaments slender, ± free; anthers short, the connective broad and forming a small apical cupular gland. Ovary 3-locular, with (1)2 or 3 pendulous, anatropous ovules per carpel, sometimes only 1 locule fertile; style simple, apically 3-lobed. Fruit a woody capsule, often asymmetrical or curved, septicidally dehiscent, leaving a 3-winged central column; exocarp often separating from endocarp. Seeds 1-3, mostly flattened, narrowly winged; testa chartaceous; cotyledons massive, cordate.

Colombia, Venezuela, Guyana, Suriname, French Guiana, Peru, northern and northeastern Brazil; ca. 25 species, 13 in Venezuela, all in the flora area.

A revision of the genus was published by K. Kubitzki (Mem. New York Bot. Gard. 29: 82-131. 1978), which included five incompletely known species (including Caraipa sp. A below). Since that time, additional collections have been made that are not identifiable to species and may represent additional new taxa. The genus is clearly in need of further taxonomic study.

Kubitzki (Mem. New York Bot. Gard. 29: 100. 1978) treated Caraipa spuria as a synonym of C. costata Spruce, but the material treated here has much larger leaves and more secondary veins than C. costata and matches closely the illustration of C. spuria in Barbosa Rodrigues (Vellosia ed. 2, 8: 9, t. 5C. 1891). Alternatively, the specimens referred to here may represent hybrids between C. costata and C. grandifolia.

Caraipa tereticaulis Tul., Ann. Sci. Nat. Bot. sér. 3, 8: 341. 1847. -Itoiyeneyek, Itu (both names Arekuna).

Evergreen to montane lowland forests, gallery forests, savanna margins, 800-1800 m; Bolívar (Amaruay-tepuí, Auyán-tepuí, Cordillera Epicara, Gran Sabana, Macizo del Chimantá [Amurí-tepuí], Upuigma-tepui), Amazonas (Cerro Coro Coro, Cerro Parú, Cerro Yapacana, Cerro Yutajé). Guyana, Peru, adjacent Brazil.

Caraipa sp. A

Shrub; leaves 6-11 × 2.5-4.5 cm, with 11-15 pairs of secondary veins, lower surface with scattered stellate trichomes; petiole 2-4 mm long; young capsule ovoid, 10-15 mm long. Seasonally flooded white-sand savanna near stream, ca. 100 m; Amazonas (Caño Pimichín). Endemic. This is known from one collection in young fruit, Maguire et al. 36377 (M, NY), and is likely a new species, but flowering material is needed.
