Rashida ji

There is some confusion. In Euphorbia cyathium has numerous male flowers, each with one stamen. So statement about numerous stamens is wrong.

Yes sir , but here is assumed that we know the cyathium has numerous male flowers which are nothing but stamens and so numerous stamens !

regards,

Rashida.

Yes Rashida ji

But to say numerous stamens would be wrong. We can say numerous male flowers. (or we can simply omit; all species of Euphorbia have numerous male flowers in each cyathium). We can't be technically wrong.
