Lousewort Pedicularis sylvatica. [sketch]

Sudbrook July 1 1860

Tube of corolla very long - Mouth of hood gaping, but when the B. [illeg], (which I twice saw visiting it) pushes down proboscis it has to drive front of head into the mouth & this stretches it open & then bows down the hood & rubs it & stigma on upper part of thorax which was yellow with pollen. Stigma protrudes even in bud & the anther is shed against a rubbing body through split beneath stigma. Anthers are fast where they lie. I also saw very minute Bee gathering pollen.

The pistil is bent in quite hook shaped & depends into gangway of corolla.
