Ptilotus Sericostachyus Subsp. Roseus
''Ptilotus'' is a genus of approximately 125 species of flowering plants in the family Amaranthaceae, and is endemic to Australia, apart from ''Ptilotus conicus'' that also occurs in Malesia. Plants in the genus ''Ptilotus'' are annual or perennial herbs or shrubs with usually hairy spikes of compact spherical, oval or cylindrical flowers. Description Plants in the genus ''Ptilotus'' are annual or perennial herbs or small shrubs, many covered with soft hairs. The leaves are arranged alternately, sometimes on branches and/or in a rosette at the base. The flowers are bisexual and borne in compact spherical to oval or cylindrical spikes, each flower with a membranous bract and two bracteoles at the base. There are five, equal, hairy, linear tepals and five stamens, sometimes up to three stamens reduced to sterile staminodes, fused into a cap surrounding the ovary. The fruit is a nut or utricle, surrounded by the remains of the perianth. Taxonomy The genus ''Ptilotus'' was first for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stamen
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains sporangium, microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''.

Prodromus Florae Novae Hollandiae
''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' (Prodromus of the Flora of New Holland and Van Diemen's Land) is a book by the botanist Robert Brown Robert Brown may refer to: Robert Brown (born 1965), British Director, Animator and author Entertainers and artists * Washboard Sam or Robert Brown (1910–1966), American musician and singer * Robert W. Brown (1917–2009), American printmaker ... published in 1810, which deals with the flora of Australia. Often referred to as ''Prodromus Flora Novae Hollandiae'', or by its standard botanical abbreviation ''Prodr. Fl. Nov. Holland.'', it was the first attempt at a survey of the Australian flora. It described over 2040 species, over half of which were published for the first time. Brown's ''Prodromus'' was originally published as Volume One, and following the ''Praemonenda'' (Preface), page numbering commences on page 145. Sales of the ''Prodromus'' were so poor, however, that Brown withdrew it from sale. Due to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower. It is a structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile (neither male nor female) tubelike tissue that surrounds the female reproductive structure or developing sporophyte. Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
