Here is a photo of 2 types of C macroptera fruit. Plants ( mine in pots ) seem pretty similar to the C.latipes image in the above post, although the mac's petiole is far longer than the leaf. Also thorns are long, thick and potentially fatal! The fruit peel is scented, a little unusually, pulp was like milder C. hystrix.
Budded scions took off well, but seedling ( only 1 planted ) seems slow, compared to the vigorous scions.
