The volume CUL-DAR66 contains notes on 'bloom'. Francis Darwin explained: "His researches into the meaning of the 'bloom,' or waxy coating found on many leaves, was one of those inquiries which remained unfinished at the time of his death. He amassed a quantity of notes on the subject". LL3: 339. See an Introduction to these folders by Christine Chua & John van Wyhe.
[175]
Nicotiana glauca & Canna warscewiczii
Aug 28' 11˚.
Sponged axis stem upper part (well covered with bloom & dry after much rain) & put sponge & gutta percha round.
Sept 11' sponge removed — earwigs within. I doubt whether gnawed— surface blackened — red wool to all — I have looked again though leaves certainly nothing to do with gnawing by earwigs — stem split is this due to swelling from absorbed water? —
Sept 17th very dark brown large patches —
Sept 24 very dark brown, looks much injured
do date Canna. warscewiczii
Sheaths of young flowers stem covered covered with powdery bloom & shoots off water beautifully — I rubbed off & put on sponge & gutta percha
Sept 11' 8˚ 30'. removed sponge— an upper & lower sheath greatly decayed & parts rotten; the underlying sheaths not injured. This not due to age, as older sheath lower down stem, quite fresh.
