Ascocentrum


Ascocentrum, abbreviated as Asctm in horticultural trade, is a small genus belonging to the orchid family (Orchidaceae). The type species is Ascocentrum miniatum (Lindl.) Schltr. ex J. J. Sm. (originally as Saccolabium miniatum Lindl.).

They occur mainly in warmer to intermediate, humid climates of the foothills of the Himalayas, in Myanmar, Thailand, Malaysia, the Philippines, Java and Borneo.

These monopodial epiphytic orchids grow on deciduous trees. They have a short, simple to bifurcate stem (max. 15-18 cm) with an upright, compact, conical to racemose inflorescence, consisting of smaller brightly colored flowers. These flowers have a prominent spur and a strap-like lip. Their bright colors vary between yellow, orange, red, orchid or cerise.

The chromosome number is 2n = 38.

They are popular among orchid lovers because they resemble the compact Vanda-like species. Nevertheless their cultivation is rather difficult.

Cinema, World War I and its aftermath

Before World War I French cinema had a big share of the world market. Hollywood used the collapse of the French production to establish its hegemony. Ever since it has dominated world film production not only economically but has transformed cinema into a means to disseminate American values.[citation needed]

In Germany the Universum Film AG, better known as UFA, was founded to counter the perceived dominance of western propaganda. During the Weimar Republic many films about Frederick II of Prussia had a conservative nationalistic agenda, as Siegfried Kracauer and other film critics noted.[citation needed]

Communists like Willi Münzenberg saw the Russian cinema as a model of political cinema. Soviet films by Sergei Eisenstein, Dziga Vertov and others combined a partisan view of the bolshevist regime with artistic innovation which also appealed to western audiences
