Salvia, hairy crimson in Flower Garden

Aug 11' 63. George has drawn —

Bifid pistil projects as straight line — tube of corolla perfectly closed by "shield", which is of shape of marrow spoon— filament short & attached to sides of corolla — The one-celled anther lies in hood — the other cell is developed into half of the spoon—

When a hair inserted into tube the spoon is pushed & this brings out th anthers — By this movement, the junction of connection of anther is twisted & by acts like spring & brings anthers into hood again.—

In old flower, I believe, the pistil becomes a little curved downwards & coheres to anthers so that when shield No

is pushed down, the pistil is brought out, which did not occur in young flower.— Insect must be large & brush stigma with back in flying down. —
