Public Comments

This malaccensis is supposed to be a seminiferous diploid, and this was the case for the plant we have checked in Guadeloupe, and whom is at the origin of the pictures on this page. But if Jaro has measured it as a tetraploid in 2018. Then "something" has happenned in the meantime...
