Alternatively Orchidaceae-Monandrae
Including Limodoraceae Horan., Thyridiaceae Dulac, Vanillaceae Lindl.; excluding Apostasiaceae, Cypripediaceae.
Habit and leaf form. Herbs (of diverse forms). ‘Normal’ plants, or switch-plants, or plants of very peculiar vegetative form (some producing but a single leaf, some achlorophyllous, three species completely subterranean (Rhizanthella)); sometimes with the principal photosynthesizing function transferred to stems, or ‘cactoid’, with succulent, photosynthetic stems; sometimes neotenic. Leaves well developed, or much reduced, or absent (sometimes). Plants succulent (often), or non-succulent; usually at least ostensibly autotrophic, or parasitic; if "parasitic", initially endomycorrhizal as a 'protocorm', usually subsequently becoming green and ectomycorrhizal mycoheterotrophic; when mature, green and photosynthesizing, or not green. Perennial; with a basal aggregation of leaves, or without conspicuous aggregations of leaves; cormous, or rhizomatous, or tuberous, or pseudobulbaceous. Self supporting, or epiphytic (predominantly), or climbing (many Vanilloideae). Helophytic, or mesophytic, or xerophytic. Leaves persistent, or deciduous (commonly so in Orchidoideae); small to large; alternate (usually), or opposite (rarely), or whorled (rarely); spiral, or distichous; flat, or folded, or rolled, or terete; ‘herbaceous’, or leathery, or fleshy, or membranous; imbricate, or not imbricate; petiolate; sheathing. Leaf sheaths tubular. Leaves with blades borne edgewise to the stem, or with blades ‘normally orientated’; simple; often jointed at the hase of the blade. Lamina entire; generally linear, or lanceolate, or oblong, or ovate; parallel-veined (but rarely distally pseudo-palmate - e.g. in Nervilia); cross-venulate (usually), or without cross-venules; auriculate at the base, or cordate, or hastate, or sagittate, or attenuate to the base, or cuneate at the base, or oblique at the base, or rounded at the base. Lamina margins usually entire. Vernation conduplicate, or plicate, or convolute.
General anatomy. Plants with silica bodies (in idioblastic ‘stegmata’, which are ‘present in the leaves of many genera’).
Leaf anatomy. The leaf lamina dorsiventral (at least mostly). Epidermis containing silica bodies, or without silica bodies (?). Stomata present; anomocytic, or paracytic. The mesophyll containing mucilage cells (with raphides), or not containing mucilage cells; containing crystals. The crystals raphides. Foliar vessels present (but sought in only two genera); with scalariform end-walls. Minor leaf veins without phloem transfer cells (Epipactis, Listera).
Axial (stem, wood) anatomy. Secondary thickening absent. The axial xylem with vessels (in 9 of the 15 genera listed by Wagner, 1977), or without vessels.
The vessel end-walls scalariform.
Root anatomy. Roots with velamen (in epiphytic forms), or without velamen. Root xylem with vessels (in the 4 genera where sought); vessel end-walls simple (in Vanilla, the only genus recorded for this feature by Wagner 1977).
Reproductive type, pollination. Unisexual flowers absent. Plants usually hermaphrodite. Floral nectaries present (but no septal nectaries). Nectar secretion from the perianth, or from the gynoecium (extrafloral nectaries also widespread). Pollination entomophilous (overwhelmingly, but the original description of the monotypic genus Crybe implies it may be cleistogamous); mechanism conspicuously specialized (in great variety, with complex morphological adaptations to the behaviour of pollinators, and often involving hygroscopic movements of pollinia).
Inflorescence, floral, fruit and seed morphology. Flowers solitary, or aggregated in ‘inflorescences’; when aggregated, in panicles, or in racemes, or in spikes, or in heads, or in umbels. The ultimate inflorescence units racemose. Inflorescences scapiflorous, or not scapiflorous; terminal, or axillary. Flowers small to large; fragrant, or odourless; very irregular; zygomorphic (the inner median member being generally enlarged and different in colour, forming the characteristic labellum — this being posterior (adaxial) in origin, but usually appearing anterior (abaxial) through torsion of the pedicel); resupinate (usually), or not resupinate (in Orthopenthea, some species of Disa, Anochilus, Herschelianthe, Prasophyllum, etc.). The floral irregularity involving the perianth and involving the androecium. Flowers 3 merous; cyclic; supposedly basically pentacyclic. Perigone tube absent.
Perianth of ‘tepals’ (usually), or with distinct calyx and corolla (the outer members sometimes green); 6; free, or joined (two or more tepals often coherent at the base, sometimes adherent to the gynoecium); 2 whorled; isomerous (but zygomorphic); petaloid, or sepaloid and petaloid; without spots, or spotted (occasionally). Tepal apex trichomes (TAT) absent (25 genera). Calyx (if the outer whorl be so designated) 3 (the median member usually ostensibly posterior); 1 whorled; polysepalous, or partially gamosepalous, or gamosepalous. Corolla (i.e. the members of the inner whorl) 3; polypetalous, or partially gamopetalous, or gamopetalous; imbricate; (labellum) spurred (often), or not spurred.
Androecium 3. Androecial members free of the perianth, or adnate (via fusion of tepals and gynostemium); united with the gynoecium (nearly always fused with the style to form a ‘gynostemium’, except in rare cases when anthers and stigma are more or less sessile); coherent (via the gynostemium); 1 adelphous; theoretically 2 whorled. Androecium including staminodes. Staminodes 2 (these morphologically anterior (usually ostensibly posterior), supposedly the abaxial pair of the inner whorl); theoretically internal to the fertile stamens. Stamens 1 (this across the flower from the labellum, i.e. anterior but usually ostensibly posterior, supposedly representing the outer whorl); reduced in number relative to the adjacent perianth; alterniperianthial (i.e. with reference to the single stamen, across the flower from the labellum); filantherous, or with sessile anthers. Anthers dorsifixed to basifixed; dehiscing via longitudinal slits; introrse; tetrasporangiate; appendaged, or unappendaged. Endothecium developing fibrous thickenings. The endothecial thickenings spiral, or girdling. Anther epidermis persistent. Microsporogenesis simultaneous. The initial microspore tetrads tetrahedral, or isobilateral. Anther wall initially with one middle layer, or initially with more than one middle layer (1 or 2); of the ‘monocot’ type. Tapetum glandular. Pollen shed in aggregates (usually), or shed as single grains (monads known in about 17 genera); when in aggregates, in tetrads, or in the form of waxy pollinia (the single grains or tetrads held together by strands of sterile sporogenous material). Pollen grains aperturate (occasionally), or nonaperturate; when aperturate, 1 aperturate, or 3–4 aperturate (rarely); sulcate, or sulculate, or ulcerate, or porate, or foraminate; 2-celled (in 14 genera).
Gynoecium 3 carpelled. Carpels isomerous with the perianth. The pistil 1 celled. Gynoecium syncarpous; eu-syncarpous; inferior. Ovary 1 locular. The ‘odd’ carpel anterior (away from the labellum). Gynoecium stylate. Styles 1 (inflexed); apical. Stylar canal present. Stigmas 1; 3 lobed (but becoming much modified in form, the apex of the median lobe forming the ‘rostellum’); wet type; papillate; Group III type. Placentation parietal. Ovules not differentiated; in the single cavity 30–100 (i.e. very numerous); non-arillate; anatropous; bitegmic (usually), or unitegmic; tenuinucellate. Outer integument not contributing to the micropyle. Embryo-sac development Polygonum-type (mostly), or Allium-type. Antipodal cells formed, or not formed (then the nuclei degenerating, e.g. Cymbidium, Dendrobium); when formed, 1–3; not proliferating; ephemeral. Embryogeny when determinable asterad.
Fruit fleshy (sometimes), or non-fleshy; dehiscent (usually), or indehiscent; a capsule (usually), or a berry (e.g. some Vanilleae). Capsules septicidal, or loculicidal. Fruit 30–500 seeded (i.e. seeds usually tiny, thin walled, very numerous and wind dispersed, but larger and crustose in some Vanilloideae where they are dispersed by grazing animals). Seeds endospermic (endosperm development arrested very early), or non-endospermic. Perisperm absent. Seeds minute. Seeds without starch. Embryo rudimentary at the time of seed release (usually), or weakly differentiated. Embryo chlorophyllous (6/7). Testa without phytomelan.
Seedling. Seed germination resulting first in development of an endomycorrhizal 'protocorm'. Seedling collar not conspicuous. Coleoptile absent. Primary root ephemeral.

General remarks. No double fertilization. Orchidaceous seed germination characteristically results in an endomycorrhizal 'protocorm', with some plants remaining achlorophyllous and not becoming photosynthetic, but most becoming photosynthetic and ectomycorrhizal. The cladistically recognised subfamilies Vanilloideae, Epidendroideae and Orchidoideae (cf. Christenhusz et al., 2017) are taxonomically unimpressive, going undefined in terms of comparative data.
Quotations.
There, with
fantastic garlands, did she come,
Of crow-flowers, nettles, daisies and
long-purples
That liberal shepherds give a grosser name,
But our cold
maids do dead men’s fingers call them.
(‘Hamlet’ iv., 7
— Orchis mascula)
I sought, the living bee to find,
And found
the picture of a bee
(Langhorn, quoted by Ann Pratt, ‘Wild
Flowers’ (1857))
Less than the coralroot, you know,
That is content
with the daylight low,
And has no leaves at all of its own;
Whose
spotted flowers hang meanly down
(Fobert Frost, ‘On Going
Unnoticed’ - Corallorhiza)

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, distributions of character states within any set of taxa, geographical distribution, genera included in each family, and classifications (Dahlgren; Dahlgren, Clifford, and Yeo; Cronquist; APG). See also Guidelines for using data taken from Web publications.
