Both anthers open by terminal pore & pollen can be squeezed out as a worm; but it does not seem to be naturally forced out – Now I suspect on some plants. Pistil would be turn to opposite side; & such pistil would be most fertile with purple anther; whereas this I presume would be most fertile with the yellow or more distant anther – as flower faces from stem, the pistil depends right down to ground – Flower regular; I could not see that nectar wd be secreted on lower side.

Oct. 30 all flowers had pistil directed on same side as in drawing – fertilised 4 pistils with pollen from near purple anthers (marked black thread sepal faces) & 4 with yellow anther petal-faces) marked with white thread.

Oct 31. refertilised them.

Jan 31. The pods so nearly ripe that Mr Horwood gathered the 2 black & 3 white thread alone had ripened.

Oct. 31. Reexamined pollen: dry both sorts [sketch] 5/7000 long & 2/7000 broad. – Distended with water, I think equal; if any difference, yellow the largest. Yellow seemed to have a larger proportion of bad grain.
