The species in " Calostoma " have been collected in regions of deciduous, temperate, tropical or subtropical forests, containing tree species from the families Fagaceae, Nothofagaceae, Myrtaceae, and Dipterocarpaceae.
32.
The genus, circumscribed in 2011, contains six species found in China . " Zangia " species grow in forests dominated by Fagaceae ( beeches and oaks ) mixed with Pinaceae ( pines ).
33.
Special collections include Amaryllidaceae, Apiaceae, Asclepiadoideae, Asteraceae, Crassulaceae, Droseraceae, Fabaceae, Fagaceae, Iridaceae, Geraniaceae, Lamiaceae, Lentibulariaceae, Liliaceae, Palmae, Pinaceae, Scrophulariaceae, Nepenthaceae, and Sarraceniaceae.
34.
The Fagaceae are deciduous or evergreen trees and shrubs, characterized by alternate simple leaves with pinnate venation, unisexual flowers in the form of catkins, and fruit in the form of cup-like ( rose motif families.
35.
In the de Candolle system it referred to what is now the family Fagaceae, while in the Bentham & Hooker system it referred to a somewhat larger family, that in addition included what is now the family Betulaceae.
36.
Fagaceae is one of the most ecologically important woody plant families in the Northern Hemisphere, as oaks form the backbone of temperate forests in North America, Europe, and Asia and one of the most significant sources of wildlife fodder.
37.
The Southern Hemisphere genus " Nothofagus, " commonly the "'southern beeches "', was historically placed in the Fagaceae sister to the genus " Fagus ", but recent molecular evidence suggests otherwise.
38.
The " World Checklist of Selected Plant Families " and " The Plant List " recognise about 330 accepted taxa ( of species and infraspecific names ) in the plant genus " Lithocarpus " of the beech family Fagaceae.
39.
The only host trees identified for " C . cinnabarinus " are " Quercus " oaks, although related members of " Calostoma " have been observed to associate with other trees in the Fagaceae family, such as beech.
40.
The older Cronquist system only included four families ( Betulaceae, Corylaceae, Fagaceae, Ticodendraceae; Corylaceae now being included within Betulaceae ); this arrangement is followed by, for example, the World checklist of selected plant families ( see external link below ).
