Very nice upload Raghu Ji, thanks for uploading....this one perhaps retains the spines even on maturity of fruit and the size of spines is also bit larger, the "kheera" we have here do not have any spines on mature fruits and also the spines on young fruits are considerably smaller..thanks again for nice sharing Raghu ji..
