Common Name Lawes' Dendrobium [English Missionary and Collector 1800's - New Guinea]

Flower Size more than 1/2" [more than 1.25 cm]

A year round blooming, medium sized, warm to cool growing epiphyte from Papua and New Guinea and Bougainville Island mist forests low on the trees or on the underside of branches at an elevation of 800 to 2000 meters with thin, flattened stems carrying broadly ovate, acute or obtuse, bilaterally flattened, distichous, thick and fleshy leaves that overlap at the base. It has a very short [less than 2", or 5 cm] raceme that arises from the old and new leafless canes with from 1 to 6, pendant, showy, highly variable, floral scented flowers that occur ar most any time of the year.

This plant is best mounted on tree fern or grown in baskets to accomodate the pendant growth habit and a somewhat dry rest is needed in the winter so reduce slightly water and fertilizer until the onset of new growth in the spring
