Flora Data (Last Modified On 10/3/2013)
Description Trees, shrubs, or scandent lianas, seldom subshrubs. Leaves simple, opposite or subopposite; petiole often glandular; blades entire, rarely lobate or irregularly toothed when juvenile, often with abaxial or marginal glands; venation pinnate; stipules present; T-shaped trichomes frequently present. Flowers bisexual, acti- nomorphic or usually obliquously zygomorphic principally by modification of 1 petal, and diversification of stamens and styles; in many-flowered, axillary pan- icles, pseudo-racemes, or umbels; pedicels sessile or articulate to bibracteolate peduncles whcch are borne in the axils of bracts; bracts and bracteoles conspic- uous or small, sometimes glandular; calyx of 5 sepals, more or less united at the base, the lobes quincuncial, rarely valvate in bud; often with a pair of conspicuous glands; petals 5, showy, free, often yellow, but also white, pink, red and violet, clawed, fringed or toothed, alternate to the sepals; the interior petal often reduced and of another color, sometimes all equal, the claw articulated with the limb; stamens (8-)10, equal or unequal, sometimes with the 5 epipetalous stamens reduced, sometimes with 4 stamens opposite the 4 glandular sepals reduced to staminodes, sometimes with the 3 stamens opposite the 3 carpels much enlarged (Stigmaphyllon, Banisteriopsis spp.), the filaments more or less connate at the base, rarely free, usually glabrous, the anthers 2-celled, basifixed or dorsifixed, introrse, dehiscing longitudinally, often with a thickened connective, sometimes glandular, sometimes appendaged; ovary superior, mostly 3-locular, (2-)3(-4)- carpellate; placentation axile, the ovules solitary in each locule, pendulous, semi- anatropous; style (2-)3 free, rarely connate, distally terete, triangularly dilated, spatulate or sometimes appendages forming a hood over the stamens, rarely with only 1 style developed, the stigmatic tissue uniform at the tip of the styles or on their adaxial angle. Fruit usually a schizocarp of 3 samaras, sometimes a drupe with 1-3 pyrenes (Bunchosia, Byrsonima, Malpighia), a 2- or 3-locular dehiscent capsule (Galphimia) or separable indehiscent cocci (Pterandra); seeds ovoid, endosperm lacking, cotyledons flat, slightly curved, folded, uncinate or spirally rolled (Byrsonima, Pterandra).
Habit Trees, shrubs, or scandent lianas, seldom subshrubs.
Note The family consists of about 60 genera with 850 species, mostly in the Amer- ican tropics. Members range from Texas and the Bahamas to northern Argentina and occur in habitats ranging from wet rain forests to arid areas. Some malpighiaceous trees produce fine-grain wood which is used locally for making furniture and in construction. The bark and wood of some species are rich in tannins and are used in small factories as dyeing or tanning material. Many species produce drupaceous fleshy fruits or acidulous juicy berries which are directly eaten or prepared into jellies or preserves. The juice of Malpighia emar- ginata Sesse & Moc. is rich is ascorbic acid (vitamin C). Some species of Ban- isteriopsis contain alkaloids, like harmaline (=yageine, banisterine, telepathine) with dramatic hallucinogenic effects. "Ayahuasca," "caapi," "yage," and "natem" are the most general common names for B. caapi (Spruce) Morton in Brazil, Colombia, Ecuador, Peru, etc. where the natives have been using it for centuries in ceremonial celebration. Other species of Banisteriopsis and other genera (e.g. Tetrapteris) also have harmaline and several other chemical derivatives with a diversified spectrum of narcotic effects, according to the recent progress of re- search in this field (e.g. Schultes & Hofmann, 1973). The generally zygomorphic flowers of the Malpighiaceae are probably bee pollinated (Croat, 1978) and the fruits are mostly wind-dispersed. A few species, such as species of Spachea, Bunchosia and Malpighia are endozoochorous per- haps at least in part by bats (Croat, 1978).
