In (P) Periwinkle (Vinca) pollen long-grained adheres in masses to sides of White tuft on stigma. — I see no different in impreg, without it be necessary that pollen shd get to summit of stigma.

To do this it must be forced upwards between bristles at end of anther which meet & cover summit of stigma. — or pollen may be carried towards mouth of corolla, where there is net of transverse hairs, & where it would be caught & might thence be carried down through hairs at end of anthers to summit of stigma. Oxslip plenty of the little Orthopt insect at bottom of these flowers—

A species of Brassica (& Sinapis?) Pollen minute, but extraordinarily so— rather small in quantity — Anther & stigma exposed in ordinary degree. — Anthers do not burst till flower expands — possibly stigma ready before — But no clear evidencerequires stronger microscop toexamine stigma more than in common flower. — Here there seems no great means of dispersion, but rather contrary, to make crosses, & onotherhand the anthers so close to stigma & stigma rather longer in one species (a)

P June. 1841. Maer. I find almost every other flower has grains of pollen scattered about anthers, & hairs on corolla & on tube of corolla. (in one case there seemed to be foreign pollen)

Much of this pollen was stained yellow, l apparently from nectar, wh is of this colour & copious at foot of Corolla— There were balls of dung & petals often eaten. — Opened some scores of flowers & found nothing within. —

(a) & flower not at all protected, that it is marvellous each stigma is not invariably impregnated by its own pollen — Very strong case. ⸮ Bees? If no still stronger —
