You will find a page dedicated to P.spec. sentang under the menu ‘Other forms’ – however, we have not yet filled it out with text. But you can find a few images there. We are gathering as much information as we can about not only this, but all those other spec. forms that you can see in the menu ‘other forms’
All I can say, is that it is one of the yet not completely described species, – and this would be the reason why it is called spec. There are quite a number of different forms which have not been described yet,- and this is one of them.
I am not sure where it is mainly found, but I am sure Peter can tell you more about this.
