Phyllocladus

Blatteibe ( Phyllocladus sp.)

Phyllocladus is a genus of five species in the family of Podocarpus plants ( Podocarpaceae ) within the conifers ( Coniferales ). They are also called leaf yew. The genus was formerly placed in its own family Phyllocladaceae, but David John de Laubenfels has it filed in 1989 in the Podocarpaceae.

Description

These are trees with growth heights of up to 30 meters. The smooth bark is dark brown to black, it comes off in large thin pieces from. The species of this genus to other genera of the Podocarpaceae differ mainly in the photosynthetic organs from, they have phylloclades that are flat green branches that look like leaves and take on the photosynthesis, because the actual leaves are reduced to small scales.

Phyllocladus species are often monoecious getrenntgeschlechtig ( monoecious ), but also ( dioecious ) populations there. Unlike many Podocarpaceae the dark brown to black seeds sit at two to 20 (usually two or three ) in cones.

Dissemination

The Phyllocladus types have their areas in New Zealand, Tasmania, Papua New Guinea, Borneo, in eastern India and the Philippines. They grow mainly in tropical and temperate highland rain forests and cloud forests.
