narrow channel by wliicli the viscid matter of the stigma 

 reaches the anther. In examining an advanced bud, the viscid 

 matter of the stigma is seen to be in large quantity and rather 

 liquid. It increases with the growth of the flower till it 

 overflows,— often before the bud opens— and, immediately on 

 its opening, inundates the pollinia, which now increase in size, 

 and either avalanche downwards, sometimes quite obliterating 

 the rostellum (Fig. 2, p. 8G); or, while retaining their position 

 in the anther, emit their tubes over the narrower portion of 

 the rostellum into the stylary canal. Very often both anther 

 and stigma become quite filled up by the multitude of pollen- 

 tubes and by the swollen pollinia. All these plants produce<I 



and well-fdled seed-capsules on every flower; but I
