features

Lithocarpus encleisacarpus is an evergreen tree .

The fruit cup (cupula) is pot-shaped. It encloses four fifths of the nut . It opens slightly from above into uneven flaps. Two to three thread-like, wavy, horizontal lines run along its surface.

Flowering time is from April to November. The fruit ripens from April to January.

Distribution and locations

The species occurs in Thailand , Malaysia , Singapore and Indonesia ( Sumatra ). It grows in tropical evergreen lowland forests, in deeper mountain forests, in pine - Dipterocarpus forests, often near rivers, at 50 to 1200 m above sea level, mostly 300 to 800 m.

Systematics

The Dutch botanist Pieter Willem Korthals described the species in 1844 and classified it as Quercus encleisocarpa in the genus of oaks ( Quercus ). In the following decades there were several proposals to assign the species to another genus:

The Danish botanist Anders Sandøe Ørsted assigned it in 1866 as Cyclobalanus encleistocarpa of the genus Cyclobalanus ; the English botanist James Sykes Gamble chose the name Pasania encleisocarpa in 1915 . In 1916 the Japanese botanist Gen'ichi Koidzumi assigned the species as Synaedrys encleisocarpa again differently; the German-American botanist Alfred Rehder put the species in 1919 as Castanopsis encleisocarpa in the genus of the pseudo- chestnut ( Castanopsis ).

With her description published in 1931, the French botanist Aimée Antoinette Camus finally assigned the species to the genus Lithocarpus under the current taxon Lithocarpus encleisacarpus .
