companied by 6-8 small, white, oval, tuberculate bodies at their 

 base, but of which I can find no trace in my specimens, and pre- 

 sume they are, therefore, not constantly present." These tubercles 

 are only on one side of the anther, and are easily overlooked. There 

 are always six of these so far as I have examined them ; they are, 

 however, easily overlooked as they are on one side only, as already 

 noted. They are very beautiful as seen under a lens, but I have 

 been unable so far to trace their morphological significance. A small 

 gibbosity on the underside of the tube near the base seems to have 

 been overlooked and may also throw some morphological light on 

 the structure of the flower. 



An interesting peculiarity is that soon after the ringent corolla 

 opens it separates from the receptacle, the style disarticulating from 

 the carpels at the same time and falling away with the corolla. In 

 most monopetalous flowers the pistil remains after the corolla fades, 

 the corolla usually falling forward and over it. There is rarely any 

 articulation by which the style separates from the carpels as in this 

 case, and as do the stamens in many flowers of other species. 



This early fading of the flower and casting off of the pistil, indi- 

 cates that the flower may have been fertilized before the opening of 

 the lobes of the corolla. An examination shows that this is really 

 the case. When the flower is fully expanded, the stamens are 

 straight, bearing the anthers under the arched upper lip. The an- 

 thers will usually be found destitute of pollen, while the longer lobe 

 of the divided style will be found with an abundance of orange col- 

 ored pollen at the apex. It will further be noted that from the 

 relative position of the forks of the style and the anthers, the pollen 

 could not readily reach this portion of the style while in the fully ex- 

 panded condition of the flower. 



If we take a matured flower bud, just ready for expansion, 

 and carefully cut away the upper lip, we find no stamens there at 

 that stage. They, as well as the style, are bent downward, grasped 

 and held in place by the incurved lower lip. Examining these un- 

 opened flowers in the early morning we find the anther cells have 

 already opened, and the sharp stigmatic point of the lobe of the 

 style in most cases is inserted in one of the anther openings and cov- 

 ered with pollen. Between eight and nine o'clock in the morning 

 the unopened buds unfold. Slowly the incurved stamens and style 

 straighten themselves, and rise to their final positions under the 

 arched upper lip. During this process the stigmatic lobes are
