The 'old' plant, where is that from Zain? Is the 'new' plant a 'wild' collected plant ?
Reason I ask is that there is the Australian form of hindsii which is slightly different to the Papua - New Guinea form.
From the notes I've had a look at, Irian Jaya isn't specified as a location in which its found. Papua New Guinea, some Islands etc are. The plant is reported as being found in specific locations also, not as a broad growing area in the regions.
