Acineta July 3d. 1866.

Labellum extraordinary - stigmatic opening so small that pollen can hardly enter & will not stick on ridges to edges to scrape off pollinia. Viscid disc large & very adhesive, not loosed by being wetted. Pollen does not become pulverulent by being kept hot & damp. But in flowers

Hardly any caudicle, but when pollinia pulled - contents come out on strongest cord - Yet in flowers some days old, pollinia separate easily from whole apparatus & are left in anther-cells useless.

I cannot conceive how flower is fertilised. Black thread

[in margin:] (Gongora)

4 flower stuck pollen with [touch] to orifice of stigma. Neither cutting & puncturing succulent parts of Labellum or irritating with brush mouth of stigma caused any viscid secretion.
