Hello Surajiy,
You asked :
"
In one of my previous reply i used the term "hook" for those "prickle" like
growth on the stem. But "hook" is not a scientific word in this case for
sure.
What will be the correct term?"
I've encountered various terms and none seem to be precise , so they are
frequently referred to as soft spine-like *protuberances*...sometimes
encountered on the petiole or main stems of Ipomoea alba but more
frequently seen on the closely related night blooming species of Ipomoea
muricata.
regards,
Ron
