(Family)

Overview

[ Back to top ]

Trees, shrubs, woody climbers, or herbs, sometimes epiphytic, sometimes with axillary spines or tendrils. Leaves opposite, occasionally alternate, rarely verticillate, fasciculate, or in a whorl; stipules usually present, often reduced to lines connecting petiole bases, sometimes reduced to petiolar ocrea or a connate leaf-sheath; leaf blade usually entire, pinnately veined or 3--7-veined from base. Flowers in cymes, these often grouped into thyrses; cymes sometimes umbel-like, scorpioid or reduced to a single flower; bracts usually small. Flowers usually bisexual. Calyx 4- or 5-lobed; lobes free or connate, mostly persistent, imbricate or valvate. Corolla sympetalous; lobes 4 or 5(--16), valvate, imbricate or contorted in bud. Stamens inserted on corolla, included to exserted, equal in number to corolla lobes and alternating with them or sometimes fewer; filaments free, much shorter to much longer than anthers; anthers basifixed, 2--4-locular, dehiscing introrsely or extrorsely by longitudinal slits, base slightly to deeply parted. Disc ring-shaped or not. Ovary superior or rarely semi-inferior, (1- or) 2(--4) -locular, placentation axillary or parietal; ovules 1 to many per locule. Style simple, terminal, persistent or deciduous; stigma usually capitate, entire or shortly 2--4-cleft. Fruit a capsule, berry, or drupe, 1- to many-seeded. Seeds sometimes winged; endosperm fleshy or horny; embryo minute, straight; cotyledons small.

Some 29 genera and about 500 species: mainly in tropical and subtropical regions of the world, absent from Europe; eight genera and 45 species (ten endemic) in China.[1]

Anthocleista

Anthocleista is a genus of tree- and shrub-like tropical gentians in the Gentian family (Gentianaceae), tribe , subtribe Potaliinae. There are about 50 species in the genus Anthocleista, native mainly to tropical Africa, Madagascar and the Mascarene Islands. Anthocleista was once placed under the family Loganiaceae, but more recent molecular, morphological, and phytochemical evidence has placed the group well within the Gentianaceae. [more]

Buddleia

Buddleja, or Buddleia () but commonly known as the Butterfly Bush, is a genus of flowering plants. The generic name bestowed by Linnaeus posthumously honoured the Reverend Adam Buddle (1662?1715), a botanist and rector in Essex, England, at the suggestion of Dr William Houstoun. Houstoun sent the first plants to become known to science as buddleja (B. americana) to England from the Caribbean about 15 years after Buddle's death.[1] [more]

Shrubs, scandent, mostly climbing or creeping. Branchlets terete, sometimes with 4 faint ridges. Leaves opposite, petiolate, connected by interpetiolar stipular rims; leaf blade margin entire. Flowers axillary, solitary, paired, or in cymes, when in cymes usually few-flowered but sometimes grouped into a thyrse; bracteoles small, narrowly triangular. Flowers 4- or 5-merous. Calyx small, deeply lobed; lobes imbricate, connate, inside with colleters at base. Corolla rotate to subcampanulate; tube thin, fleshy; lobes thin to thick, fleshy, valvate in bud. Stamens exserted; filaments very short, flat; anthers 2- or 4-locular, connate or free, base 2-parted, introrse. Ovary small, 2-locular, with 1--4 ovules per locule. Style mostly long, slender; stigma capitate or 2-cleft. Berries red, globose, 1-seeded or more. Seeds ellipsoid to orbicular, concave on hilar side but convex on other side; seed coat thin; embryo tiny, almost cylindrical; endosperm thick, horny.[2] [more]

Mitragyne

Mitrasacme

Herbs, delicate annual or perennial. Leaves opposite along stem and/or in a whorl at base, subsessile; stipules absent. Flowers axillary and/or terminal, solitary or in pedunculate umbel-like cymes which sometimes rebranch to form irregular compound umbels, 4-merous, white or yellow, rarely pale blue. Calyx campanulate, 2--4-lobed; lobes valvate. Corolla campanulate [salverform or urceolate], often bearded at mouth, tube short to long, lobes exduplicate-valvate in bud. Stamens inserted on lower half of corolla tube; filaments much longer than anthers; anthers introrse, extrorse, or rarely latrorse, included to slightly exerted, 2-locular. Pistil glabrous. Ovary superior to slightly inferior, with many ovules per locule. Style one, base usually parted, rarely 2 separate styles; stigma capitate or 2-cleft. Capsules globose to subglobose, opening by apical loculicidal slits, 2-horned, horns terminated by a style which may be split or remain partly connate, many-seeded. Seeds minute, cylindric-ellipsoid to angular; seed coat thin reticulate to verrucose or almost very minutely papillate; endosperm fleshy.[3] [more]

Mitreola

Herbs, annual or perennial, erect to creeping, branched or not. Branches terete to 4-angled. Leaves opposite, sessile or petiolate; interpetiolar stipules well developed to reduced to a transverse ridge. Inflorescences terminal and/or axillary, usually long pedunculate, 2 or 3 or more branched, branches scorpioid; bracts small, sepal-like. Flowers sessile or shortly pedicellate, 5-merous. Calyx usually parted almost to base, lobes with membranous margin. Corolla urceolate to campanulate, tube as long as to longer than lobes, lobes imbricate in bud. Stamens inserted at base to middle of corolla tube, included; filaments ± as long as anthers to shorter; anthers usually ovate, introrse, 2-locular. Ovary semi-inferior, 2-locular, with many ovules per locule. Styles cleft at base; stigma capitate or 2-cleft. Capsules 2-horned or 2-lobed, with both carpels dehiscing along ventral suture; horns or lobes erect, divergent, or curved inwards, terminating by style halves; many-seeded. Seeds small, ± subglobose to ellipsoid; seed coat smooth, reticulate, or verrucose; endosperm fleshy; embryo linear.[4] [more]
