Hartfield. July 17th 1870

Lilium martagon common or Turks Cap.

[sketch]

Petals reflexed, spotted reddish purple with cream in middle of each, which ants visit & also Hive Bee Hence fluid in nectar. Pistil in early open flower straight & dependent. Stamens curl up. & so does ultimately pistil into many right angles, & slightly rotate in turning up so as to brush against at least one anther which shed their pollen laterally -Hence contrivance for self-impregnation. But the gangway to all the nectaries is circular; & large moth or Humble Bee could in passing from one to other be apt to brush all anthers & stigma. Hence no objection to my law of stigma bent into gangway. Contrivance for self-fertilisation & for crossing. Other anthers wd be useless without this contrivance. This flower explains that at Kew in Hot-house - namely Gloriosa superba, with its angularly bent pistil.

[in margin:] When the corolla drops off, the pistil to great extent straightens itself

The Kew Bees visit common orange Alstrœmeria, with 2 upper petal striated first one & then another turn up into gangway & when pollen shed end of pistil turns up into gangway & the 3 divisions of stigma expand. So as in first monoecious plant
