Horse-chesnut from Ld Cranworth Park. May 23. 1860

One truss – 87 flowers

second 177

third 158

fourth 185

say 150 on average.

From Down. 140 rather small truss

do 188 fine truss.

I examined flowers from 6 different trees of Holwood & in all it was clear that many male flowers considerably open before females & so lose their pollen uselessly.

I examined tissues of flowers from high up tree at Down & same arrangement, all anthers in some cases had shed pollen before pistils protruded on the truss.

May 23d I conclude I may say a multitude of male flowers produced uselessly, at least the greater number of anthers of such flowers are produced uselessly - Better say a vast amount of pollen wasted.

Hooker says he has looked & confirms my account Same in Maple.

After careful examination I may say no difference in pollen of Hermaphrodite & male flowers.
