Aug 3d — Lythrum 3 forms from Southampton 2 sets of flowers carefully compared.
Long-styled, filaments of longer stamens white, in other 2 forms bright pink — stigma in this form considerably larger & slightly rougher owing to slighter greater length of papillæ than in mid-form styled; & latter than in short-styled.
Tall anthers in short-styled = taller a trace a trace higher than stigma of long-styled; rather longer anthers of mid-styled a trace shorter than stigma of long-styled.
The latter anthers of Short & Long-styled a trace above stigma of midstyled.
The shorter anthers of A. & B. long & midstyled, a little long higher than stigma of short-styled.
The 3 sets may all all be said to be approximately equal to the corresponding stigma.—
The correspondence in height most striking.—
The rectangular bending of stigma varialbe in short-styled.

Pollen
The 2 green pollen seemed to me identical except in shade of green variable.
The pollen of long-stamens of of long-styled = in length to pollen of short stamen of short-styled, but decidedly broader; for the grains of these shorter stamens of short-styled are extremely narrow!!!
The pollen of short-stamens of mid-styled is smaller than the pollen of short-stamen of short-styled & equally narrow.
The pollen of short stamens of long-styled was so many imperfect grains & immature that I could not compare it.—
