The fruits and leaves of the New Guinea wild lime are known:  I found the juvenile form. (Many citrus of Oceania have a juvenile form).  It looks very similar to Citrus wintersi (Brown river finger lime):  |

I just had my first fruits of warburgiana:  They look nearly alike the fruits of wintersi !!!  Between the wintersi and the warburgiana there are 300 km as the crow flies that can only be traveled by plane or boat.
So there is very little chance that there is mutual pollution. The possibility of warburgiana having a juvenile form for the leaves and for the fruit should be well considered. In any case that makes them very close species, one of which will remain in a juvenile state. Wintersi would be a neotenic form of warburgiana. If this is true it would be a hell of a discovery! To know if it's true, we just have to wait few years to see if it turns in a mature warburgiana.  |

That looks like Wintersii to me. I thought Warburgiana was a roundish lime with leaves more like C. inodora?

Yes it looks like wintersii but the leaves are not exactly the same shape and it was found under a warburgiana tree!... It's why it is a kind of mistery.
The leaves of warbugiana are longer and thinner than the wintersii ones.

Everything I have read about C. warburgiana refer to round fruits and leaves that are closer to Citrus inodora (which I do have). The plant you are describing as the juvenile form of Warburgiana looks very much like my C. papuana. Isn't it possible that a seed from C. papuana could grow under C. warburgiana? Might birds eat the fruit Papuana and disperse the seeds under Warburgiana? Birds travel enormous distances and are known to disperse seeds. This seems plausible to me but I don't know the distance between territories of each species.

Yes it's true, as shown on the first picture. I took this picture at Bubuleta near Alotau 'PNG).
This place is 400km far from the nearest C. wintersii.
> Isn't it possible that a seed from C. papuana could grow under C. warburgiana?
It is not likely. There was not one seedling but many of them under the warburgiana tree and local people said it is the seedlings of that tree.
It is a real mystery!

Its more likely that PNG and Nth QLD Citrus are dispersed by the Cassowary, a large flightless bird. Many other similar size and shape fruit are also dispersed by Cassowary.
If they were dispersed by long ranging flying birds, they would be more widespread over the countryside.

In fact, there is 375 km between Portmoresby and Alotau. The wintersii are north of Portmoresby and Bubuleta is east of Alotau. This makes more than 400 km.
Cassowari and birds could not explain why the seedlings are under a warburgiana tree. Smith Malcolm proposed:
"Given that it was an old agricultural research station it is possible that C. wintersii was growing somewhere nearby".

what about warburgeriana seedlings in "captivity". Aren`t there any plants to compare with?

Yes, that would give us the answer!

Did you collect seed from this site? Is it possible you have a hybrid?

Thanks Lazz for the pics Anyone interested in the Cassowary, some nice videos and pics on this site..Spotted Wild www.facebook.com/spottedwild/The Cassowary species in Australia, also occurs in PNG. There are also two other species in PNG. |
