Thyrse
A thyrse is a type of inflorescence in which the main axis grows indeterminately, and the subaxes (branches) have determinate growth.

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Indeterminate Growth
In biology and botany, indeterminate growth is growth that is not terminated, in contrast to determinate growth that stops once a genetically predetermined structure has completely formed. Thus, a plant that grows and produces flowers and fruit until killed by frost or some other external factor is called indeterminate. For example, the term is applied to tomato varieties that grow in a rather gangly fashion, producing fruit throughout the growing season. In contrast, a determinate tomato plant grows in a more bushy shape and is most productive for a single, larger harvest, then either tapers off with minimal new growth or fruit or dies. Inflorescences In reference to an inflorescence (a shoot specialised for bearing flowers, and bearing no leaves other than bracts), an indeterminate type (such as a raceme) is one in which the first flowers to develop and open are from the buds at the base, followed progressively by buds nearer to the growing tip. The growth of the shoot is not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Syringa
''Syringa'' is a genus of 12 currently recognized species of flowering plant, flowering woody plants in the olive family or Oleaceae called lilacs.

Vitex Agnus-castus
''Vitex agnus-castus'' (also called vitex, chaste tree / chastetree, chasteberry, Abraham's balm, lilac chastetree, or monk's pepper) is a plant native of the Mediterranean region. It is one of the few temperate-zone species of ''Vitex'', which is on the whole a genus of tropical and subtropical flowering plants.David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK. Vitex is a cross-pollinating plant, but its self-pollination has been recorded.Verein für Arznei- und Gewürzpflanzen Saluplanta. 2013. ''Handbuch des Arznei- und Gewürzpflanzenbaus'' volume 5 Arznei- und Gewürzpflanzen L–Z, pages 192–199. Verein für Arznei- und Gewürzpflanzen Saluplanta: Bernburg, Germany. (set). Theophrastus mentioned the shrub several times, as ''agnos'' (ἄγνος) in ''Enquiry into Plants''. It has been long believed to be an anaphrodisiac – leading to its name as "chaste tree" – but its effectiveness for such action re ...
