Broom 1866 May 14th Monday

White Thread 6 fl. not touched to see if spont. spring open; 18th not open. After 3 weeks all dropped off, & apparently none had opened

Black Wool 6 fl. which had spontaneously sprung open, but weather had been stormy & windy disturbed the net.

none set a pod

12 fl Black Th. I sprung them open, but prevented their gathering pollen from shorter stamens. —

May 17th 18th

Two Black & white threads a second dose of pollen of longer st 6 fl. after being spring & getting own pollen from long stamens, were 4 days afterwards again fert by pollen of long stamens. & perhaps from short & none none from short

Black & white Th. Thread 7 flower do a dose of pollen of shorter were given to those which had been sprung 4 days before & thus had got their own pollen from long stamens & not from short

May 6 May 18 Flowers (white wool) were sprung & so got own pollen from long stamens & were then instantly fert. by pollen from short stamens from another Bush.—

These Six flowers under net net were snapped off & 4 days afterwards, so I believe for own pollen from longer stamens & were then at once fertilised by pollen from short stamen from another bush & 5 pods were produced & so very fertile.

I think no mistake, but case very odd, 6 fl. were snapped off & so got I believe own pollen from long stamens, but none from own shorter stamens, & 4 days afterwards were fert. by pollen from long stamens of other plant, & produced 3 pods of which one very fine.— 1866 At same time 7 flowers in same way were fert. by pollen of shorter stamens of distinct plant & did not set one pod: → (zz)
