Term Synonyms Category Limitation Definition
gummy texture Highly viscous and sticky, liquid or more or less deformably solid, sometimes more or less elastic.
gynaecium STRUCTURE See gynoecium.
gynandrium pl. gynandria = column, gynostemium STRUCTURE A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae.
gynandrous architecture flower Having the androecium adnate to the gynoecium.
gynecandrous reproduction taxon Monoecious, each inflorescence having a distal sector with only pistillate flowers and a proximal sector with only staminate ones.
gynobasic insertion style Apparently arising from the ovary base.
gynodioecious reproduction taxon Having some plants with only bisexual flowers and some with only pistillate ones.
gynoecium pl. gynoecia var. gynaecium STRUCTURE The pistil(s) of a single flower together with any ontogenetically equivalent or subordinate structures present, taken collectively; the total female (ovule-producing) structural complement of a single flower. It may include one to many pistils, each simple or compound.
gynomonoecious reproduction taxon Having all plants with both bisexual flowers and pistillate ones.
gynophore = hypogynium; < stalk, stipe (broad sense, not recommended) STRUCTURE The basal portion of an ovary when constricted and stalk-like above the level of perianth insertion, bearing the main body of the pistil at its summit.
gynostegium pl. gynostegia < corona STRUCTURE An androecial corona, typically consisting of distinct hood- and/or horn-shaped enations that rise above the anthers; esp. in Asclepiadaceae.
gynostemium pl. gynostemia = column, gynandrium STRUCTURE A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae.
…gynous = …pistillate, …pistilled architecture flower, gynoecium Having the number of pistils indicated by the prefix; as in monogynous, pentagynous, polygynous.
habit CHARACTER General appearance and/or function, usually including explicit or implicit reference to one or more aspects of habitat or other features of the external environment; a logically imprecise traditional category of terms that overlaps conceptually with architecture, arrangement, duration, insertion, location, orientation, position, shape, and texture.
haft STRUCTURE The narrow portion of a structure that is notably constricted.
hair = capillus; > glochid, glochidium; < cilium, trichome STRUCTURE A hair-like trichome.
hair-like = capillary, capillate solid shape Finely filiform; resembling a hair.
halberd-head-shaped 1 = hastate base laminar structure Having two generally triangular lobes, one to either side, oriented more or less perpendicular to the central axis.
halberd-head-shaped 2 = hastate plane shape Basically triangular with an acute apex and two large, widely divergent basal lobes, each generally triangular and distally acute; like the stylized outline of the broad lateral face of a halberd head.
half-inferior = subinferior position ovary Having its proximal portion enclosed by a floral tube casing, the more distal portions of the perianth and/or androecium thus arising between its base and apex.
half-obterete = semiobterete solid shape Inversely half-terete; obterete but flattened on one side.
half-terete = semiterete solid shape Terete but flattened on one side.
hamate = hooked, uncinate apex Having a recurved terminal portion that resembles a hook.
hanging = pendent, pendulous orientation stalked structure Having the stalk strongly recurved from its base, the main body oriented downward. See also nodding (cernuous, nutant).
hapaxanthic = monocarpic reproduction plant Normally reproducing sexually only once, then promptly senescent.
