Cleistogene Flowers

Drosera rotundifolia kept in cool – Hot-house — there up several flowers stamens, which never opened — Whilst very small, show tips of white petals (through tips of co sepals) cohering & covering anthers with pollen still Enclosed & pollen-tubes penetrating stigma.— pollen-grain few, though apparently more than in Viola, & some arachis — Strictly cleistogamic.— yet sometimes certainly produce perfect flowers which I have been assured by Mr Wallis open only early morning. When little flowers are set, the white petal turn from brown & stale colour, over ovarium, entering a multitude of seeds — Three flowers produce long, stem peduncle.— /over

June 25. D. Anglica produces in greenhouse rather more perfect fl. showing more petals, & aperture just open tempering, but hardly enough from insect to visit it — Pollen in shed, but remain round anthers in a cross & penetrate the stigma.—
