19a. Longitudinal section of a nearly expanded bud of E. tetragon a F.v.M., Stirling Range, Western 

 "Australia, showing inflection of the filaments, ovules, and top of ovary. 



19b is the operculum of the same, and 19b (6) and 19a (a) are the same organ. (See also fig. 16.) 



The inside of the operculum is more or less striate, and a small cleft, compressed or angular, 

 stipes-like attachment projects from the centre of the top. 



If a longitudinal section of a bud is made, this stipes-like appendage is seen to project 

 downward towards the style, and sometimes it exceeds that organ. When it is longer than the 

 point (stigma) of the style, the latter is seen to grow to one side, as it were, to allow the projection 

 to pass down towards the base of the style. Or it may be that the stalk-like appendage is of 

 much harder substance than the style, and in that case the style is forced to bend when it comes 

 in contact with it. 



This appendage is rarely seen, and requires investigation. In the bud-section its presence 

 seems to accentuate the division of the operculum into four petals, and the " appendage " may 

 be of the nature of a stipes or claw.

 absence of the gland in the Terminales. (See p. 530.)

This also shows a specimen of a versatile anther. All anthers may be versatile except Terminales 



and Porantheroidese.
