ment upwards irritates the anthers, causing them to dehisce, and 

 the ciliated edge of the indusium, in passing, brushes the free 

 pollen into its cup. The indusium, thus having outgrown the 

 anthers, and being filled with pollen, becomes inflected against 

 the induplicated auricles of the upper divisions of the corolla, as 

 well as contracted at its mouth, thus locking up the pollen. By 

 this action of the indusium, the upper portion of the middle of 

 the style becomes dorsally exserted between the upper lobes of 

 the corolla, and thus causes a false or premature opening of that 

 part of the corolla; but, really, it is internally blocked by the 

 induplicated auricles. This opening is apparently of no direct 

 service in the pollination. I have noticed a "native Bee" visit- 

 ing a flowtr at this stage, and trying to force its way through 

 this false opening, but eventually giving up the struggle, and 

 flying away. 



The indusium, so far, contains the stigma, as yet rudimentary, 

 in its base; and not till now does the flower open, having those 

 limbs on the upper side and beyond the auricles, reflex ed over 

 the gynsecium ; the indusium still pressing hard against the 

 auricles, and beginning to re-open, and the three lower lobes of 

 the corolla spreading platform-like, intimate to insects that all 

 is ready for their kind oflices. The stamens are withered and 

 dejected, and the only entrance is along the lower limb, and then 

 down the partially closed throat of the flower, where a little force 

 is needed by the insect; but in doing so, the upper lobes of the 

 corolla, with their auricles, become forced apart, exposing the 

 mouth of the indusium, which is then brought into contact with 

 the insect's back, and the pollen, if ripened sufliciently, which 

 condition is intimated by the fact that the indusium has now 

 re-opened, becomes brushed on to the back of the insect, by the 

 ciliation of the indusium. Thus, also, is seen that this ciliation 

 is for the double purpose of brushing in the pollen from the 

 stamens, and again brushing it on to the insect. 



From many observations, I have noticed that, as soon as the 

 indusium becomes completely inflected, the stigma, which hitherto 

 had remained rudimentary at the base of the indusium, begins to 

 develop rapidly in the form of a two-lobed tuberculated body.
