English: A usually flat-topped or convex flower cluster in which the main axis and each branch end in a.noun. Location of inflorescences in Sinningiacyme-Cyme meaning, definition and translation. For example, Archippe, daughter of Dikaiogenes, among other beneficent acts, paid for a sacrifice and banquet for the people. Chapter 9 Nomenclature and postharvest physiology. A cyme (rhymes with lime) is an inflorescence that is broad and often flat-topped. An inflorescence in which each terminal growing point produces flowers.
Cyme Meaning Plus A Pair
Kubitzki and J.Kadereit (eds.), The families and genera of vascular plants, vol. "Black Hill" normally have one flower per axil.How can one even speak of an inflorescence in that case, with just one flower?A plant of that species sometimes has more than one flowerPer axil, and when it does have a second flower, it is inIssue of Gesneriana on the development of pair-flowered cymes.It has scanning-electron microscopy pictures to show the sequenceIn which the various flowers and bracts are initiated and theirTwo of the species used in his investigation are sinningias:The pair-flowered cyme is the base inflorescence type in the Gesneriaceae.It is found throughout every branch of the family.However, it is not restricted to the Gesneriaceae.This picture shows an inflorescence on Penstemon tenuis,Which is native to the south central United States.The central flower has opened first, and its pair flower is just about to open.There are two secondary cymes, each with one terminal flowerbud plus a pair flowerbud.Plantaginaceae, still not far from the Gesneriaceae.(such as Tetranema) also have pair-flowered cymes.[References: Anton Weber's treatment of the family Gesneriaceae in K. PFC = pair-flowered cyme.In the pair-flowered cyme, the top flower and the pair flowerUsually are in a plane perpendicular to that of the secondaryCymes - that is, they would be coming toward you out of the** a single flower (both and absent),** two flowers ( present but both absent),** more than two flowers ( and one or more present).What usually does not happen is for one or more to be presentWithout the pair-flower being present.The best way to get the idea of a cyme (and its pair-flowered variant)Is to closely examine a saintpaulia flowerstalk or a multi-floweredBecause the flowerstalks are larger than in other gesneriads,It isn't as obvious, but the pair-flowered cyme is the basicSomewhat ironically, one of the best pictures I have of aPair-flowered sinningia cyme is on a hybrid.This picture of Sinningia reitzii x cardinalisShows the end flower opening first, then the pair flower directly beneath it,And lastly, one on each side, the two still-developing one-flowered "cymes".Another closeup of a pair-flowered cyme can be found on theTo show that the pair-flowered cyme is a unifying feature of the gesneriadFamily, here is a picture of a gesneriad from half a world away.This is the pair-flowered cyme of a Lysionotus,Note that each side flower has a bud beneath it, in the pair-flower position.Thus, each "side flower" is actually a secondary pair-flowered cyme.Sinningia sp. Cyme Inflorescence upon which the topmost or outermost flower opens firstFor those of you with a little background in computer science or mathematicsOr programming, raceme and cyme can be defined recursively as follows (theRest of you don't worry if you didn't know what that meant):In English, here is what those diagrams mean:A raceme is a stem from which one or more pedicels develop at a node,And which continues to another node, from which one or more pedicelsDevelop, and which continues to another node, from which one or moreOn a raceme the lowest pedicels and their associated flowers developFirst, followed by the next lowest, and so on.A raceme tends to peter out in one or more buds which don't fully develop.A cyme is a stem terminating in a flowerbud, but which might have,Below the flowerbud, a node from which one or two cymes develop.This definition sounds circular (and that is what is meant byThe word "recursively" above), but really isn't.After some number of branchings, the stem terminates in a singleFlowerbud, and there the circularity ("recursion") stops.On a cyme the terminal flowerbud develops first, followed by theTerminal flowerbuds of the cyme's node's cymes, followed by the terminalFlowerbuds of the cyme's node's cyme's node, ad not quite infinitum.Trust me, look at the branching of a multiflowered stalk on an AfricanViolet or streptocarpus, and all will become clear.Instead of ending in a single flower, it ends in one or two,With the extra one (the pair flower) directly below the first.Again, F = flower, C = cyme, and something in brackets means0 or 1 of the unit. Gladiolus, foxglove, smithiantha, Diastema racemiferum). Raceme Inflorescence upon which the bottom flowers open first(e.g.
Sinningia pusilla A stem extension bearing individual flowers or cymes in the axilsOf ever-diminishing leaves, the uppermost of which are small bracts.(I'm sure there is a better term for this, but I can't find it.If the secondary inflorescences were racemes and not cymes, one could call it a panicle.)A specialization of the Extended Axis, in which the flowers are borne inClusters on a "platform" - that is, from a whorl of (usually) three bracts.There may be more than one such "platform" on the axis.A cluster of flowers on a peduncle which appears to be more or lessThe peduncle may have bracts where the pedicels or secondary pedunclesThe distinction between this and the Extended Axis is thatThere is an abrupt shift between vegetative stem and TerminalPeduncle, while the shift to the Extended Axis is gradual. Sinningia reitzii [well-developed perennial stem,Multiple flowers per axil on pair-flowered cyme] Chautems.]This is a drastic oversimplification, but there are five general waysIn which the flowers can be organized in a sinningia.The first three types below characterize indeterminate growth (no predetermined numberOf nodes per stem), while the last two characterize determinate growth (predeterminedPlease note that these are descriptive categories, not developmental ones.I'm not a professional botanist and have no assurance that all sinningias that form(for instance) "platform" inflorescences do so in the same way.Furthermore, inflorescence type does not correspond well to the taxonomy of theGenus Sinningia (that is, species with the same inflorescence type are not groupedTogether in the family tree), so that inflorescence type seems quite mutable duringStrictly speaking, all sinningias have axillary cymes.That is, the flowers are borne on inflorescences which are cymes and originateThere are no racemes in Sinningia and no inflorescences which do not originateIn the present context, however, we use the phrase axillary cyme toRefer to inflorescences originating from the axils of fully-developed leaves onOne or more flowers in the axil of a fully-developed leaf.If there are more than one, the flowers are arranged in a pair-flowered cyme.
