Prockia
''Prockia'' is a genus of flowering plants in the family Salicaceae. It consists of approximately six species of shrubs and small trees native to the West Indies, Mexico, Central America, and South America. Its type species, ''Prockia crucis'', is highly polymorphic and has a broad distribution, from Mexico and the West Indies to Uruguay and northern Argentina. The genus name of ''Prockia'' is in honour of Christian Leberecht von Prøck (1718–1780), a Danish baron. He served as Governor-General of the Danish West Indies colonies from 1756 to 1766. It was first described and published in Syst. Nat. edition.10, Vol.2 on page 1074 in 1759. Historically, ''Prockia'' was characterized by having pseudo-axile placentation (i.e., parietal placentae that intrude into the center of the ovary and eventually fuse, appearing axile) and 3-merous flowers and lacking nectaries.Sleumer, H.O. 1980. Flacourtiaceae. ''Flora Neotropica'' 22: 1-499. However, discoveries of new species have confounded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salicaceae
The Salicaceae is the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') included the willows, poplar, aspen, and cottonwoods. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the Scyphostegiaceae and many of the former Flacourtiaceae. In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera (''Salix'', ''Populus'', and '' Chosenia''). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales. Under the new circumscription, all members of the family are trees or shrubs that have simple leaves with alternate arrangement and temperate members are usually deciduous. Most members have serrate or dentate leaf margins, and those that have such toothed margins all exhibit salicoid teeth; a sali ...

Pineda (plant)
''Pineda'' is a genus of flowering plants in the family Salicaceae. It contains two species of shrubs: ''Pineda incana'', which is native to the Andes of Ecuador and Peru, and '' Pineda ovata'', which is native to the Andes of Bolivia.Alford, M.H. 2006. A taxonomic revision of the Andean genus ''Pineda'' (Salicaceae). ''Kew Bulletin'' 61: 205-214. ''Pineda'' is unique among Salicaceae in that the species have 4-5 sepals and petals, hermaphroditic flowers, receptacular disk glands (=nectaries), and outer filamentous staminodes. It is one of few genera of Salicaceae that occur at high elevations. Formerly placed in the heterogeneous family Flacourtiaceae,Sleumer, H.O. 1980. Flacourtiaceae. ''Flora Neotropica'' 22: 1-499. ''Pineda'' is now classified in tribe Prockieae of Salicaceae, along with close relatives ''Prockia'', ''Banara'', ''Hasseltiopsis'', and ''Neosprucea''. ''Pineda'' was named in honor of Antonio Pineda, a Guatemalan botanist who was coordinator of the naturalists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Leberecht Von Prøck
Christian Leberecht von Prøck (1718-1780) was a Danish baron. He served as Governor-General of the Danish West Indies colonies from 1756–1766. In 1768, Pröck became a diocese commander over Iceland and the Faroe Islands. He died on 4 September 1780 in Copenhagen. In 1759, Patrick Browne ex Carl Linnaeus published ''Prockia'', a genus of flowering plants from Central America, and South America, in the willow family, Salicaceae. Then in 1886, botanist Baill. published '' Prockiopsis'', a genus of flowering plants from Madagascar Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa ..., belonging to the family Achariaceae and both genera were named in Christian Leberecht von Prøck's honour.

Hasseltiopsis
''Hasseltiopsis'' is a monotypic genus of flowering plants in the family Salicaceae. It consists of one species of trees: ''Hasseltiopsis dioica'', which is native to Central America. Formerly placed in the heterogeneous family Flacourtiaceae,Sleumer, H.O. 1980. Flacourtiaceae. ''Flora Neotropica'' 22: 1-499. ''Hasseltiopsis'' is now classified in Salicaceae, along with close relatives ''Prockia'', '' Pineda'', ''Neosprucea'', and ''Banara ''Banara'' is a genus of flowering plants in the family Salicaceae (formerly in Flacourtiaceae).

Flacourtiaceae
The Flacourtiaceae is a defunct family of flowering plants whose former members have been scattered to various families, mostly to the Achariaceae and Salicaceae. It was so vaguely defined that hardly anything seemed out of place there and it became a dumping ground for odd and anomalous genera, gradually making the family even more heterogeneous. In 1975, Hermann Sleumer noted that "Flacourtiaceae as a family is a fiction; only the tribes are homogeneous." In Cronquist's classification, the Flacourtiaceae included 79–89 genera and 800–1000 species. Of these, many, including the type genus ''Flacourtia'', have now been transferred to the Salicaceae in the molecular phylogeny-based classification, known as the APG IV system, established by the Angiosperm Phylogeny Group. In the list below, the Salicaceae are circumscribed broadly. Some taxonomists further divide the Salicaceae '' sensu lato'' into three families: Salicaceae ''sensu stricto'', Scyphostegiaceae, and Samyd ...

Plant Reproductive Morphology
Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involve ...

Gustav Karl Wilhelm Hermann Karsten
Gustav Karl Wilhelm Hermann Karsten (6 November 1817, in Stralsund – 10 July 1908, in Zoppot) was a German botanist and geologist. Born in Stralsund, he followed the example of Alexander von Humboldt and traveled 1844-56 the northern part of South America ( Venezuela, Ecuador and Colombia). From 1856 to 1868, he was a professor at the agricultural college in Berlin, afterwards serving as a professor of plant physiology at the University of Vienna (1868–72). In 1881, at the suggestion of David Friedrich Weinland, Karsten became convinced of the correctness of Otto Hahn's organic theory of the chondrites and, as a result, wrote an essay entitled "Die Meteorite und ihre Organismen" in which he declared his support for Hahn's theory. He died 1908 in Berlin- Grunewald. As a taxonomist, he was the binomial author of many botanical species. Selected bibliography * ''Florae Columbiae ...'' 1859–1869.
