Different size of seeds

[Phoenikakias]

They are from to separate plants of purportedly the same kind (Arenga engleri). The bigger plant produces constantly biiger fruits, while conversely the smaller one produces constantly smaller fruits. Is the different size of motyer plants that defines size of fruits or do the plants belog to different varieties within the same sp or even do plants belong to different spp?

[Pal Meir]

In older books (of the 1980s) on the vegetation of the Yaeyama islands of the SW Ryuukuus they made distinctions between two kinds of Arenga (Japanese: kurotsugu), and only the Arenga growing on Iriomote island were called komi kurotsugu which means »Arenga with small fruits«. Whereas the normal kurotsugu was labeled as Arenga engleri, the komi kurotsugu was thought to be Arenga tremula.

Do you have in your vast archive of pictures any of the 'komi kurotsugu'? Preferably with some scale but please no Japanese postage stamps, I am not familiar with their size...

many times the seed size means nothing, my friend has a arenga engleri producing small fruit, while in a square in the beautiful city of Pompei, there are some arenga engleri that produce large enough fruits
