May 11th 62. Pelargonium

(This includes description of Peloric flowers)

Bunyan had central peloric, without nectary & with one of upper petals pink (!) fertilised with pollen of peloric flower of Scarlet Queen & marked with Red thick thread) Also fertilised one of lateral flowers on same truss with pollen of same peloric flower of Scarlet Queen & marked with black worsted. It will show whether 2 Peloric will produce seeds.

(I fertilised (& marked with black thread) the peloric flowers of Scarlet Queen with pollen from large very pale flesh coloured. Pelargonium multiflora alba of which we have several.

May 24th fertilised another peloric flower with do black thread; & a common flower with do & marked with white thread this I believe or am almost sure dropped off

May 25 crossed 2 common flowers of Scarlet Queen with pollen of short stamens of above flesh-coloured pelargonium - black worsted.

[1v]

3 black & 1 White

June 8th fertilised a peloric fl. of Bunyan by pollen of semi-peloric central flower of anther white & pink Pelargonium No 56. Marked with white bobbin.

Also a common flower with do pollen marked with white bobbin & black thread

10 Common flower of Topsy by Aspasia peloric

Two allied to Climax Unnamed - dark flesh common fls by peloric pollen (White) of Scarlet Queen (white). This "unnamed" had a great many pods due to Bees.

That with 2 White threads refertilised by peloric of Agnes

18th Peloric fl Aspasia by own peloric pollen black

common fl. of Bunyan by peloric pollen of Etna

common fl of Etna by peloric of Aspasia

July 2. Agnes by own pollen common fl. (String)

(over)

[3v]

The peloric flower of Etna & Aspasia have only 5 long stamens alternating with filaments. So that very regular! See [illeg] for some genus with 5 stamens & abortive stamens: Can all the crossing which Pelargonium has undergone caused this strong tendency to reversion. Scarlet Queen do 5 stamens

(Peloric fl. of Agnes has 6 petals & 6 stamens)
