Masdevallia, abbreviated Masd in horticultural trade, is a large genus of flowering plants of the Pleurothallidinae, a subtribe of the orchid family (Orchidaceae). There are over 500 species, grouped into several subgenera. The genus is named for Jose Masdeval, a physician and botanist in the court of Charles III of Spain.
The Pleurothallidinae are a neotropical subtribe of plants of the orchid family (Orchidaceae) including 29 genera in more than 4000 species.
Ulmus pumila, the Siberian elm, is a tree native to Central Asia, eastern Siberia, the Russian Far East, Mongolia, Tibet, northern China, India and Korea. It is also known as the Asiatic elm and dwarf elm, but sometimes miscalled the 'Chinese Elm'. It is the last tree species encountered in the semi-desert regions of central Asia. Described by Pallas in the 18th century from specimens from Transbaikal, Ulmus pumila has been widely cultivated throughout Asia, North America, Argentina, and southern Europe, becoming naturalized in many places, notably across much of the United States.
The hybrid elm cultivar Ulmus × intermedia 'Coolshade' is an American hybrid cultivar cloned from a crossing of the Slippery, or Red, Elm Ulmus rubra and the Siberian Elm Ulmus pumila at the Sarcoxie Nurseries, Sarcoxie, Missouri, in 1946. At Arnold Arboretum, where there was a specimen, herbarium material was labelled Ulmus pumila 'Coolshade'.
The Siberian Elm cultivar Ulmus pumila 'Park Royal' is a cold-hardy selection raised by the Sheridan Nursery, Toronto, Ontario, Canada.
The hybrid elm cultivar Ulmus 'Den Haag' is a Dutch development derived from a chance crossing of the Siberian Elm cultivar Ulmus pumila 'Pinnato-ramosa' and the Belgian Elm Ulmus × hollandica 'Belgica'. S. G. A. Doorenbos (1891-1980), Director of Public Parks in The Hague, finding that seeds he had sown in 1936 from the Zuiderpark 'Pinnato-ramosa' had hybridized with the local 'Belgica', selected six for trials. The best was cloned and grafted on 'Belgica' rootstock as 'Den Haag'; it was planted first in that city, then released to nurseries elsewhere in the Netherlands. The other five were also planted in The Hague.
The Siberian Elm cultivar Ulmus pumila 'Pendula' is from northern China, where it is known as Lung chao yü shu. It was classified by Frank Meyer in Fengtai in 1908, and introduced to the United States by him from the Peking Botanical Garden as Weeping Chinese Elm. The USDA plant inventory record (1916) noted that it was a "rare variety even in China". It was confirmed as an U. pumila cultivar by Krüssmann (1962).
The hybrid cultivar Ulmus 'Androssowii'R. Kam., an elm of Uzbekistan sometimes referred to in old travel books as 'Turkestan Elm' or as 'karagach' [:black tree, = elm], its local name, is probably an artificial hybrid. According to Lozina-Lozinskaia the tree is unknown in the wild in Uzbekistan, and apparently arose from a crossing of U. densa var. bubyrianaLitv., which it resembles, and the Siberian Elm Ulmus pumila.
The Siberian elm cultivar Ulmus pumila 'Pinnato-ramosa' was raised by Georg Dieck, as Ulmus pinnato-ramosa, at the National Arboretum, Zöschen, Germany, from seed collected for him circa 1890 in the Ili valley, Turkestan by the lawyer and amateur naturalist Vladislav E. Niedzwiecki while in exile there. Litvinov (1908) treated it as a variety of Siberian elm, U. pumilavar.arborea but this taxon was ultimately rejected by Green, who sank the tree as a cultivar: "in modern terms, it does not warrant recognition at this rank but is a variant of U. pumila maintained and known only in cultivation, and therefore best treated as a cultivar". Herbarium specimens confirm that trees in cultivation in the 20th century as U. pumilaL. var. arboreaLitv. were no different from 'Pinnato-ramosa'.
The Flora of Colombia is characterized by 130,000 species of plants that have been described within Colombian territory.
Banksia rufa subsp. pumila is a subspecies of Banksia rufa. It was known as Dryandra ferruginea subsp. pumila until 2007, when Austin Mast and Kevin Thiele sunk all Dryandra into Banksia. Since the name Banksia ferruginea had already been used, Mast and Thiele had to choose a new specific epithet for D. ferruginea and hence for this subspecies of it. As with other members of Banksia ser. Dryandra, it is endemic to the South West Botanical Province of Western Australia.
Masdevallia veitchiana, also known as Veitch's masdevallia or king of the masdevallias, is an orchid species of the genus Masdevallia.
Masdevallia davisii, or Davis' masdevallia, is a species of the orchid genus Masdevallia. It is also known as the orchid of the sun and was known to the Incas as qoriwaqanki – due to its similarity in form to the red Masdevallia veitchiana, known as waqanki.
The Siberian elm cultivar Ulmus pumila 'Aurea' was released by the Honze nursery in China shortly before the Beijing Olympics in 2008. Little information is currently (2008) available, and although the species is apparently U. pumila, it is advertised as a 'Chinese Elm', which is U. parvifolia.
Masdevallia ionocharis, the graceful violet-blue masdevallia, is an epiphytic orchid in the Masdevallia genus of orchids. Its name is derived from the Greek words ion meaning violet and charis meaning grace.
Masdevallia coccinea, the little flag, is a species of orchid occurring at high altitudes in the Eastern Cordillera of Colombia.
Masdevallia ignea is a species of orchid endemic to Colombia.
Masdevallia vargasii is a species of orchid found from southern Colombia into central Bolivia and Guyana.
The Siberian Elm cultivar Ulmus pumila 'Zhonghua Jinye' is an introduction from China.
