Myrmecodia platytyrea - Biak Island, Irian Jaya


Recommended Posts

One of the diagnostics for M. platytyrea subsp platytyrea is that its leaves have elliptic lamina or are broadest below the middle, 12x5- 20x9 cm., apex short to long-acuminate, base abruptly narrowed, but it is reported to be the most common of the two sub species in the wetter north west of New Guinea Island.  Yet?

Sub species antoinii supposedly has has leaves wider in their upper half according to the Huxley & Jebb revision (1993).

Also the leaves in these plants are far more undulate than those I am familiar with in Australia and Central Province, PNG.

Another new one? ;)

All the best

Hello Andreas. It certainly is possible but without knowing the range of variations throughout all of a possible species habitats, it would not be wise to make a judgement especially from a photograph.  One day one hopes, we will have a more defined method of deciding what makes a taxon.
