Rhamnus lanceolatus
Long pistilled
Diameters of globular pollen grains
Short pistilled Rh Lanceolata
Diameters of globular pollen grains
Short pistilled
Long pistilled
Diameters of short & long pistilled are place on two lines leave out Z as it is nearly twice the size & is probably an error on measuring it is seen than 15 of S-pistilled equal 14 of L-pistilled therefore L-pistilled pollen grains the largest.
