Shrewsbury July 1841.

My present with nature about intermarriage.

Possible in all flowers – but self impregnation the common order of events.

Pansies often - greatest difficulties from never visited by any insects – nor is it possible to know whether it ever crossed (? try with bird [illeg] )

Galium & Phlox never visited & doubtless many other flowers. —

(NB Bees sometimes impact Phlox, but never Heartsease)

Fumaria & P[illeg] often no theoretical difficulty, but […ctically] I do not know what insect visits them. —

[2 words illeg]  show which Thrips can effect.

Orchideæ show which some unknown insect bigger then Thrips can effect – yet never visited 

Vinca is

Aug a certain number of seeds settling in each flower [illeg] must form intermarriage

another case. Rhubard & Cabbages is well known that Bees visit Rapa Fields

I believe show what small beetles & butterflies can effect. Lychnis Dioica what flies can for certainty they are not much frequented by Bees. –

But Rhod. Azaloides shows even what grains effect pollen from very few apparent Bees.

Sorrell shows assuming all the swollen seeds are good which wind can effect.

Spurge shows how little one can judge of how fortification is effected.

All Dioecious &c more plants, except when very small & abundant – No flower being closed except as in Antirrhinum when really open to insects – position of stamens with respect to nectar – the astounding number of flies &c & the quantity of pollen, these transplanted as shown by Thyme – all under intermarriage highly probable whether it is sufficient to breed from in some tribes very doubtful.
