Bulbophyllum sinapsis

A rather uncommon orchid from the paradise of PNG. This is a slow growing one which is vegetatively rather similar to the related B. micranthum. The bloom, as you can see,  is such a work of art. 

The leaf litter plant

Just like tank forming Bromeliads of the New World and Bird Nest ferns (Asplenium) in our back yard, the leaf-litter plant or (Agrostistachys borneensis) traps fallen leaves and debris at its rosette crown and absorbs the nutrients after their decomposition.

This is a common and rather untidy small tree from the forests of SE Asia. It is a member of the Euphorbia family.
