[25]

May 30 62: 2 spikes of Arachnites sent me by Mr Oxenden, kept in water (& young flowers opened) for more than week & intentionally jarred strongly & often, the pollinia did not fall out. The Shining lateral knobs at base of Lab. are larger than in Bee; if these be perforated by insects, then this wd be important difference. A more important one, is that the stigmatic surface is more perpendicular & therefore more open with respect to base of Labellum in the Bee than in Arachnites; evidently so as allow surface to be struck by its own pollinia in the Bee.
