Pollen of Long-styled form Shorter stamens 6 flowers fertilised (Black silk) 69 61 88 66 [total] 284/6 4/6 set (perhaps 5/6 see below) |
Pollen of mid styled form Longer stamens 4 flowers fertilised (White wool) no pod no pod no pod no pod

Pollen of mid-styled form Shorter stamens 6 flowers fertilised (Black wool wood) 93 77 48 43 4/6 set 6 |
Own pollen (green) Longer stamens 3 flowers fertilised (White thread) no pod no pod no pod 7 |
Own pollen Shorter stamens 3 flowers fertilised (Black thread) 64 — I suspect I crossed this flower as if it had been black silk no pod no pod
|
Two branches fertilised with Camel B. carelessly not one pod |
Self-fertilised only 2 pods 20. very poor seeds 6 (could hardly have got pollen, without I dropped any from other plant as under separate net.— |
I might perhaps cross few of these, but not of midstyled
1862 — 88 flower fertilised
1863 126 will have to be fertilise
