備註: 雞屎藤屬留意要看efloras版foc, 中國現時取用puff 1991 的分法,棄W. C. Ko 1999在FRPS版的分法 國際上採用的主流都是puff 1991 中國,到2011 年 陳濤跟Taylor寫foc這個部分才採用puff 1991的分法。中間有20年混亂 thanks crawford info FOC: Shrubs, subshrubs, or vines, unarmed, usually extensively twining, usually with fetid odor when bruised. Raphides present. Leaves opposite or infrequently in whorls of 3 or 4, without or sometimes with (Paederia foetida, P. spectatissima) pubescent domatia; stipules caducous or persistent, interpetiolar, triangular to bilobed. Inflorescences axillary and/or terminal on main stem or often on short lateral stems, thyrsiform, paniculate, cymose, or spiciform, several to many flowered, sessile to pedunculate, bracteate with bracts sometimes enlarged and stipitate [to petaloid]. Flowers sessile to pedicellate, bisexual, monomorphic. Calyx limb (4 or)5(or 6)-lobed [sometimes with calycophylls]. Corolla white, pink, or purple, funnelform to salverform usually with tube very slender then abruptly enlarged shortly above base, inside pubescent in tube and throat, sometimes fenestrate near base; lobes (4 or)5(or 6), induplicate-valvate in bud, with margins often crisped to irregular, rarely shortly trifid at apex. Stamens (4 or)5(or 6), included, inserted at various levels near middle of corolla tube, included; filaments reduced [or sometimes developed]; anthers dorsifixed. Ovary 2(or 3)-celled, ovules 1 in each cell, erect, basal, anatropous; stigmas 2, filiform, included or exserted. Fruit characteristic: dry, drupaceous becoming schizocarpous, globose or compressed globose to compressed ellipsoid, with calyx limb persistent and occasionally becoming enlarged; exocarp dry, membranous to papery, usually drying shiny, at maturity fragmenting; pyrenes ("diaspores") 2(or 3), indehiscent, membranous to leathery, hemispherical to flattened, oblong to ovate in outline, entire to winged, rarely pubescent (P. yunnanensis), sometimes borne on a persistent carpophore; seeds with testa thin; cotyledons broadly cordate; radicle short, hypogeous. | |
