C3 and C4 plants

[MichaelXY]

Aren't C3 plants mostly monocots and C4 plants mostly eudicots?

Some grasses and canes (Sugar cane) are C4. Cane and grasses are typically monocots.

Can you please tell me if there is any other plant which has C3 and C4 subspecies besides Alloteropsis semialata thanks!

Nice information sharing!!

Well to tell you that whether C4 plants save water more than C3 plants, then the answer may be YES!

and After Stomata closure, exchange of CO2 is stopped (not the water conc decreases). It is the reduced level of CO2 which become rate limiting than water in case of high temperature, (MrMistery man). Also the closing of stomata is triggered to stop excessive water transpiration, that means water would be more inside the cell when stomata is closed.
and I think there is no more subspecies reported in other plant which has C3 and C4 pathway than Alloteropsis semialata.
or
I may be wrong....

Time to find out
