This is commonly a flat-topped or convex flower-cluster.Quassinoids: subclass of triterpenoids (nortriterpenoid) composed of 19-20 carbon atoms.inorescence architectures (panicle, raceme and cyme). On which they are borne grows indefinitely, e.g., as in a spike, raceme, corymb. Many verticillasters with reduced bracts can form a spicate (spike-like) inflorescence that is commonly called a spike. A verticillaster is a fascicle with the structure of a dichasium it is common among the Lamiaceae. A reduced raceme or cyme that grows in the axil of a bract is called a fascicle.Compare with cyme and spike. Kaempferol and myricetin.The flowers at the base of the central stem develop first. Variation in inorescence morphology can then be explained by the plant’s ability toQuercetin: a common flavonol c.f.
Cyme Vs Raceme Series Of FlowersPetiole.Rachis ( rhachis), more specifically, inflorescence rachis = inflorescence axis, c.f. Panicle, see also pedicel, peduncle.Rachis: that part of the axis of a pinnate or more highly compound (or pseudocompound) leaf that bears leaflets, pl. Cyme and panicle, for variants, see botryoid, capitulum, corymb, fascicle, raceme, spadix, spike, thyrse, umbel.Raceme (in Poaceae): of an inflorescence with unbranched axes bearing spikelets, , the axes may be solitray, digitate, or scattered along a higher order axis, c.f. SRL.Raceme: an indeterminate inflorescence, the axis producing a series of flowers on lateral pedicels, the oldestAt the base and the youngest at the top, adj. RRLD: root length density, or root length per unit volume, c.f. Cochleate, contorted, contortiplicate, crumpled, decussate.Quinolizidines: alkaloids derived from lysine and with two fused 6-membered rings that share a nitrogen.Quinones: the general name for aromatic compounds that have two atoms of hydrogen replaced by two atoms of oxygen, usually yellow, red, or orange, see anthraquinones, benzoquinones, hydroquinones, naphthoquinones.Quinque- (prefix) = five of whatever is qualified by the prefix. Axial parenchyma.Reaction wood: wood often with a distinctive anatomy and position formed where a branch joins the stem, see compression and tension wood.Recalcitrant: of germination, and sometimes also pollen viability, the seed or pollrn grain needing to remain hydrated if germination is to occur and not tolerating drying or freezing (and often even temperatures below 10 0 C), c.f. Fusiform initials.Ray parenchyma: radially orientated xylem parenchyma in the wood, see ray type, c.f. Disc floret.Ray initials: a kind of cambial initial in the vascular cambium, vertical series of low cells the division and subsequent differentiation of which that produce the rays, c.f. InAsteraceae, ligulate, with a split monosymmetric corolla, c.f. Incurved.Reduced: anther wall development in which the primary parietal layer gives rise to two secondary parietal layers, the outer producing the endothecium only, the inner producing the tapetum only, c.f. Gynoecial nectary.Recurved: curved or curled downwards or backwards, c.f. Appendicular epigyny.Receptacular nectary: a nectary in the flower supplied by branches of the receptacular or androecial vasculature, c.f. Epigyny is due to development of axial tissues (Kuzoff et al. Concaulescent, also epicaulescent.Receptacle: the axis of a flower on which the perianth, androecium and gynoecium are borne in Asteraceae, used to refer to the often swollen and apically flattened part of the stem bearing the flowers and inflorescence bracts in monilophytes, the part of the sorus bearing sporangia.Receptacular epigyny: of epigyny, when the floral apex is initially convex, but after gynoecial initiation the periphery of the floral apex expands and raises, forming a basin in the center of which the carpels are borne and on the periphery of which the perianth members and androecium are borne, i.e. Honeywell security system manual m7240Foliate, induplicate.Reflectional: on of the basic types of symmetry, as in the identity between a figure and its relection in a mirror, e.g. In palms, the units of the leaves having their abaxial surfaces facing each other, inverted V-shaped, c.f. Crumpled, decussate, induplicate, open.Reduplicate: of plicate leaves, esp. Microsoft virtual wifi miniport driverGums, mucilages, latex, oils, waxes.Resupinate: of floral symmetry, the flower twisted through 180 o, e.g. Extrareproductive nectary.Resins: lipid-soluble terpenes or phenols, c.f. Apomixis, amphimixis.Reproductive nectary: a nectary that is found on the inflorescence or flower or associated structures - a positional definition - c.f. The leaf is not strictly bipinnate, even-pinnate, odd-pinnate, pinnate or tripinnate, and reins could be found hanging from a palmate leaf.Reiteration: of plant architecture, when the characteristic construction of the individual is repeated by branch systems that develop on a plant after damage, or sometimes as the result of natural causes.Reparatory strand: a strand of vascular tissue that fills ("repairs") the leaf gap left by the outgoing leaf trace, a branch of the sympodial units making up the central stele of seed plants.Replum: when placentation is parietal, = a "false" septum joining the placentae.Repent: plant with stem growing along the ground, usually rooting from the nodes, see ascending, decumbent, erect, procumbent.Reproduction: the general process by which new plants are formed, in particular c.f. Inflexed.Regular (of floral symmetry) = polysymmetric.Reins: of a palm leaf, the ribbon-like band(s) along the sides of the leaf blade hanging from the tips of the pinnae - n.b. Rotational and translational.Reflexed: bent sharply downwards or backwards, c.f.
