Thesepollinia emit their tubes over the rim of the rostellum, almostobliterating it, into the stylary canal. On the opening of theflower and the retraction of the anther-case, the most internalpollinia may sometimes be found in the condition of loosegrains unaffected by the inundation of viscid matter. In itsfertilisation this species of Eria seems to resemble Dendrobiumchrysanthum. The mode of fertilisation described as occurring in Oplirijsajrifera by Mr. Darwin, I found to be followed very closely bya species of Eria near to E. javensis, in which the anther-capshrivels up backwards after rupturing, so as to disclose the.

I observed them inthe forest, as well as grew a few of them in Mr. Lashs garden,and every specimen was fertilised in the same way. In opening OG A NATURALISTS WANDERINGS its lock
