英语翻译The Families of Flowering Plants L.Watson and M.J.Dallwitz Gesneriaceae Dum.Including Cyrtandracaceae N.Jack,Didymocarpeae (Didymocarpaceae) D.Don,Ramondiaceae (Ramondaceae) Godr.& Gren.ex Godr.,Replicataceae Dulac Habit and leaf form.Herbs (usually,sometimes slightly woody),or shrubs,or lianas (rarely); non-laticiferous and without coloured juice.‘Normal’ plants,or plants of very peculiar vegetative form (sometimes); sometimes remarkably neotenic (with spectacular reduction of the axis — e.g.Streptocarpus,where the plant has but one leaf which represents a cotyledon,the other cotyledon having atrophied early).Leaves well developed.Plants non-succulent.With a basal aggregation of leaves,or with neither basal nor terminal aggregations of leaves.Self supporting,or epiphytic (commonly),or climbing; climbers root climbers.Mesophytic.Heterophyllous (members of leaf pairs often very different in size),or not heterophyllous.Leaves opposite (usually),or alternate (rarely),or whorled (rarely); ‘herbaceous’,or leathery; petiolate; simple; epulvinate.Lamina entire (usually),or dissected; rarely pinnatifid; pinnately veined; cross-venulate.Leaves exstipulate.Lamina margins entire,or serrate,or dentate.Leaves without a persistent basal meristem.Domatia occurring in the family (Mitraria); manifested as pits.Leaf anatomy.Stomata anisocytic (often very large).Adaxial hypodermis present,or absent.Lamina dorsiventral; with secretory cavities (accompanying the xylem,in a few genera),or without secretory cavities.Secretory cavities when present,containing oil,or containing resin.The mesophyll with sclerencymatous idioblasts,or without sclerenchymatous idioblasts.Minor leaf veins without phloem transfer cells (Aeschynanthus,Isoloma,Mitraria).Stem anatomy.Secretory cavities present (in a few genera),or absent; when present,with oil,or with resin.Cork cambium present; initially deep-seated,or superficial.Nodes unilacunar,or tri-lacunar,or penta-lacunar.Cortical bundles present (a single one,in the stem ridge of Rhynchoglossum obliquum),or absent.Medullary bundles present (e.g.Klugia,Monophyllaea,Rhynchoglossum).Secondary thickening developing from a conventional cambial ring.Xylem with fibre tracheids (Coronanthera),or without fibre tracheids; with libriform fibres,or without libriform fibres (Coronanthera); with vessels.Vessel end-walls simple.Wood partially storied (VPI,some Cyrtandra species),or not storied ); parenchyma paratracheal (or very sparse,or absent).Reproductive type,pollination.Plants hermaphrodite,or monoecious (rarely).Pollination entomophilous,or ornithophilous,or cheiropterophilous.
