is in Viburnum^ congenitally adnate with the nucleus. In Vibur- 

 num the ovary is generally 1-celled, in V. Tinus 2-celled, and the 

 solitary pendulous ovule hangs transversely, so that the raphe is 

 neither turned towards the placental axis, nor diametrically away 

 from it. The testa is formed of the walls of the nucleus and its 

 adherent integument. The cavity of the ovary is full of stellate 

 hairs. The three stigmas are free in a very early stage, and the 

 ovule is developed in one of them above the plane passing through 

 the base of the calyx-lobes. The three stigmas hence probably 

 represent as many free ovaries which afterwards combine, and the 

 developed cells are produced downwards forming cavities in the 

 peduncle.
