Trypsin — Leaves taken out Sp 13 — 11 to 11.30 a.m

Lime {2nd basal — plenty of starch, I think everywhere

(2nd apical none)

Lime — no starch in either basal or apical part. 1 specimen of each —addedK1+1 again to both, lots of starch in base

(Normal lime — starch everywhere nourished)

Ivy starch in both about equally — I think not equal to normal leaf.

Hazel — 1st apical specimen some starch, bad specimen

1st Basal — great deal of starch gone but not all I think of these 2, there is more starch in the apical-

2nd apical — lots of starch

2nd basal very little starch

3rd apical one piece, plenty, one none

Normal leaf plenty of starch, but not every stoma has starch & some patches of stomata have less than other places.

Normal leaf 2nd specimen — Again a good many with no starch

Cherry Apical (1st specn) no starch (readded 1 do)

Basal (1st) Patches of starch & patches of none ( readded 1 do)

Basal 2nd Hardly any (readded do)

Normal — everywhere starch

(Cherry 2nd Apical No starch certainly)
