The observed monstrosity consisted in an 9 inflorescence 

 bearing a staminate flower, of which however the 6 stamens 

 transform themselves in various degrees into stigmas, viz. three 

 throughly, the fourth one partly in such a way that both 

 stigma and anther are well recognizable, while n" 5 and 6 

 show nothing but the first indications of a stigma. This mixed 

 nature of the same organ, which has been also observed by 

 F. Benecke in Begonia boliviensis '), recalls the stamino-carpella 

 of Savastano as seen and described by this authority in mon- 

 strous Oranges and Lemons-), viz. small organs connecting with 

 the external shape of stamens the internal characters of both 

 stamen and pistil. 



Begonia hybrida tuberosa. 



Coll. June 1898 Soekaboemi (Java) by W. van Andel. 



Pistillate flower with five perianth-leaves and a superior ^) 

 ovary. This ovary bears 5 short triangular wings each termi- 

 nating in a style. The styles are somewhat branched, twisted 

 and undulate. On the top of the ovary there is an additional 

 style without connection with any wing. At the base of this 

 stvle three excrescences are to be seen on their whole surface 

 covered with ovules. 



Another female specimen showed a flower, in which a branch 

 of the style was crowned with a little pitcher producing a small 

 bud in its centre.
