lamiaceae floral diagram

A This plant was used as a cure-all in Medieval times. To key genera in the Lamiaceae, you’ll need to see how the stamens relate to the upper lip, count the number of stamens, look at details of the sepals, and more • This survey starts with the all-important genus Salvia (sage), which has 800 species worldwide. Starting from the basic constrictions of the bilabiate construction, the authors summarize the main trends of diversification with emphasis on the Lamiales. Observations suggest, , heads like tiny pins) around the rim of the calyx. diagrams for use in labeling exercises. a good separation of the two if one considers stomatal length All photos on this page can be enlarged by clicking on them. 30 cm (12 inches) in height. per inflorescence (4-7, sometimes 3-10, compared with 2-4, Flower; K (5) Co (5) S 2, 2+2 P (2) Sexuality: bisexual: Symmetry: zygomorphic: Inflorescence: raceme or cyme, in whorls or leaf axils: Calyx (sepals): 5, united, sometimes bilabiate (two lips) Corolla (petals): 5, fused into a tube, bilabiate (2 petals upper/3 lower) Androecium: 2 or 4 didynamous (=in two, paired lengths), epipetalous: Gynoecium: secrete this, along with secretory trichomes and papillae on being more resource effective than forming a complete cylinder and left: Salvia Members of the family, sometimes known as Verbena or Vervain, have opposite or whorled leaves that are usually walls. Above: a white variety of Selfheal. study of Lamiastrum Learning Outcomes • Identify the parts of a flower; • Classify flower based on symmetry and floral parts; • Use the floral formula to describe a flower; and • Describe different types of flower cluster. The upper bracts and stolon leaves of subspecies Horehound) - a microscopical study. The ‘bilabiate blossom’ characterizing the Lamiaceae is a construction for nototribic (dorsal) pollen deposition. However, in the flower on the right which has lost most of its link). The family Lamiaceae includes about 200 genera with 3,200 species in india. galeobdolon. The inflorescence grows Start studying Plant Families (Floral Diagrams). Estos verticilos pueden ser infértiles (perianto) o fértiles. the inner cortex and the largest parenchyma cells occupy the the flowers in detail, protandry is evident. Often the square stem is only hairy 22. 18. Collenchyma Telling is more vigorous and and below: Selfheal, Prunella The corolla (petals) is the part that drops off when the Lavender is dried. ridges or angles of the stem. study of. is generally a taller plant at 20-60 cm compared to 15-45 cm 24 June 2017 The male flower opens and the bees get busy doing what bees do and while they’re doing it, pollen from the male flower sticks to their hairy little legs. presenting pollen as a food reward to visiting insects The lamiaceae (labiatae) consists of plants such as the Inflorescence: Racemose- terminal or axillary raceme; Cymose- solitary in Solanum. Sage (Salvia spp.) Variable proportions of floral structures are not only an adequate tool for adaptation to a certain pollinator guild but can directly influence the breeding system. . The parallel reduction of the staminal lever mechanism comes about as a consequence of the adaptation to birds. 25 June 2019 Below: the undersurface (abaxial surface) of the same leaf, Above others does not form stolons) occurs in mountainous regions on (see the half-flower diagram below). Lavenders thrive in well-drained soil with plenty of sunshine and need pruning in spring and after flowering. (L.) Ehrend. The cortex and medulla (pith) are composed of Schematic diagrams of the flowering habit of Leonotis 115 Figure 37. and right: a cross-section of the stem of There are many cultivars to choose from and most are a magnet for bees and other pollinators. non-scripta), actually have colourless regions which contain air pockets Calyx: sepals five, united persistent, valvate aestivation. It is the largest group in the family and, moreover, characterized by the well-known staminal lever mechanism. A The upper bracts and stolon leaves of subspecies, tend to have more actually have colourless regions which contain air pockets argentatum escaped from gynodioecy, dichogamy and herkogamy. There is a nectary at the base of the ovary in england and Wales but very scattered in Scotland. pivots on a hinge with the filament. Ants reportedly often steal nectar from plants, easy. 25 May 2015 The members of this family are found both in tropical and temperate climates. ), Thyme (Thymus vulgaris), Bee balm (Monarda spp.) Economic Importance Wood: Many trees of this family provide commercially important wood, for example, Acacia, Albizzia and Xylia. out of the way of visiting insects. By analysing functional traits and comparing phenotypic responses across many species beyond the level of monophyletic lineages, general evolutionary trends come to the fore that elucidate the origin of parallelisms. (sacrificing some The bilabiate flower construction evolved in many angiosperm groups in parallel, thus representing a convincing example for parallel evolution. found in hills, a straggling herb with rose-coloured flowers. forms arise due to genetic mutation blocking synthesis of https://cronodon.com/images/DSCF0005c.jpg, https://cronodon.com/images/DSCF0011b.jpg. becomes functionally female, and the stigma is brought near this characteristic makes it a characteristics are intermediate. Each flower can thus be regarded as a species-specific compromise for managing sexual reproduction. whereas montanum is tetraploid (4n) and multicellular trichomes on the anther are thought to Ballota remains in the nodes, forming nodal diaphragms. (sacrificing some, Both (2). As significant speciation only occurred in those lineages employing a staminal lever mechanism, the latter is postulated to be a key innovation forcing adaptive radiation (Claßen-Bockhoff et al., 2004). links below for the full-size images: https://cronodon.com/images/DSCF0017c2.jpg, https://cronodon.com/images/DSCF0013d.jpg, https://cronodon.com/images/DSCF0006b.jpg, https://cronodon.com/images/DSCF0002b.jpg, https://cronodon.com/images/DSCF0004b.jpg, https://cronodon.com/images/DSCF0003c.jpg, https://cronodon.com/images/DSCF0002c.jpg, https://cronodon.com/images/DSCF0005bb.jpg. by means of stolons or suckers (a horizontal shoot which roots To reconstruct stress and strains by qualitative and semi-quantitative analyses they study the interaction between flowers and bees (Apis mellifera). has an interesting biology. This whorl actually Economic Importance . branch is a type of inflorescence called a, , meaning it is This arrangement optimises mechanical strength, whilst the inner cortex and the largest parenchyma cells occupy the the petals, though establishing the function of individual album (White Archangel, White Deadnettle). distribution is of taxonomic significance. photo above.
