 75 yu. in diameter. Disc and anthers yellow. Style terete,

[Auctiba also comes here, but its flowers are dioecious, 

 and it is therefore treated on p. 268.] 



(b) Corolla coming off as one whole, not consisting of 

 separately inserted petals {Gamopetahe). 



[Care must be taken in determining this character, 

 since some gamopetalous corollas are so deeply divided 

 that the segments can be torn off separately with little 

 violence e.g. Holly.] 



(i) Ovary superior, the corolla inserted on the [For (ii) 

 floral axis round its base. see p. 342.] 



(a) Stamens free from the corolla, or at least [For (j3) 

 not inserted in its tube: hypogynous. ^^^P' ' 



* Stamens equal in number to the lobes 

 of the corolla i.e. isostemonous. Anthers 

 not awned. Flowers small, actinomorphic. 



t Parts of the flowers in fours. Corolla small, 

 white, rotate, the petals nearly separate. 

 Shrub, with glossy spiuescent leaves. 



Ilex Aquifolium, L. Holly. The student may find 

 the four white petals just coherent at the base, where the 

 alternate stamens are affixed, and may then look for it as 

 gamopetalous. See p. 288.
