up and inundating, by the cliannels at the side of the rostelliiin, 

 at least the most external pollen masses on each side. These 

 pollinia emit their tubes over the rim of the rostelliim, almost 

 obliterating it, into the stylary canal. On the opening of the 

 flower and the retraction of the anthor-case, the most internal 

 pollinia may sometimes be found in the condition of loose 

 grains unaffected by the inundation of viscid matter. In its 

 fertilisation this species of Eria seems to resemble Dendrohium 

 clirysanthmn. 



The mode of fertilisation described as occurring in Oplirijs 

 ajyifera by Mr. Darwin, I found to be followed very closely by 

 a species of Eria near to E. javensis, in which the anther-cap 

 shrivels up backwards after rupturing, so as to disclose the

pollinia, which at once, even when quite shaded from wmd and 

 all other disturbances, begin a slow tortuous movement, during 

 which they fall into their own stigmas, as seen m i ig. -o, p. J6.

 opening its florets at all (Figs. 25, 26). I observed them in 

 the forest, as well as grew d few of them m Mr. Lash s garden 

 and every specimen was fertilised in the same way. In opening
