Houlletia Roraimensis
''Houlletia'' is a genus of large-growing epiphytic orchids native to Mexico, and possibly also Guatemala through Central America to Bolivia. was established with the publication by Brogniartt of ''Houlletia brocklehurstiana'' in 1841. The genus is named in honor of orchid collector and grower M. Houllet, French orchid collector in Brazil, later the director of the ''Botanic Jardin des Plantes'' in Paris, 19th century. Description The plants have ovoid, ridged pseudobulbs, each bearing 2-4 large, pleated leaves. The inflorescences begin from the base of the pseudobulbs and are always pendant, with fleshy, showy flowers hanging downward ("nodding") on a simple raceme. The dorsal sepal is free and the lateral sepals form a short mentum with the column foot. The petals are similar to the dorsal sepal but smaller. The lip is deeply 3-lobed, the lateral lobes are upcurved and the mid-lobe is spreading. The anther is imperfectly two-celled and there are two waxy pollinia, cleft, with v ...

Paraphyly
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...
