on the ovarium (the female flowers have three). In one of these 

 abnormal female flowers there were some naked ovules between 

 the stigmas beside those included in the ovarium. In the first 

 plant all the ovules of the male flowers are naked. There are 

 some unripe pods on the second plant, all of which are produced 

 by normal § flowers ; as soon as they are ripe I shall send you 

 seeds of this second plant also.

Introductory Eemarks to Mr. BBOUGnTON's Paper on- Hybridism 



among Cinchona?. By J. E. HowaAId, F.L.S. 



[Read March 3, 1870.] 



At the particular request of Mr. Broughton I engaged to 

 read the accompanying paper. The author also wished that I 

 should adduce any arguments that might occur to me against any 

 point that he has mentioned. This his desire, I conclude, arose 

 from my having frequently urged the study of the different kinds 

 cultivated in India, in order to the selection of the sort most adapted 

 for the production of Quinine, as a necessary point to be attended 

 to by those who would cultivate with profit. I have also expressed 

 my belief in the general permanence of the forms, even of the 

 subspecies or varieties of the plant. 



I have nothing to urge, however, against the views expressed by 

 Mr. Broughton as to the occurrence of hybrids, but, on the contrary, 

 living specimens which have occurred in my own limited sphere of 

 observation which seem to me to confirm their truth. I am more 

 doubtful about the occurrence of hybridism in the native places 

 of growth of the Cinehonse, as I do not think there can be in ge- 

 neral the same favourable conditions for the interference of the 

 pollen of different species that occur in their cultivated state. I 



thrown 



the botanical arrangement of the gecLis as is expressed by my 



correspondent.
