Den. secundum

[pheli]

The Taiwanese name for this species is ' Brush dendrobium'. It is from the lowlands in SE Asia and i used to consider this species could not stand lower temperatures here. But luckily they seem do well outdoors all years round. They just grow and grow without distinct rest period, even in cold winter. They flower in late summer here. The tiny flowers is 0.5 cm around and therefore it is somewhat difficult to take a closeup image.
