APPENDIX- 23 



with parallel cells, and introrse, A hint may be obtained from 

 this accidental deviation from the ordinary form of development, 

 and we may reasonably infer from the circumstance, that the uni- 

 localar hippocrepiform anther of Anihotroche, seen also in many 

 genera of the Scrophulariace<2 and Myoporaceo^^ is not formed, as 

 has been usually supposed, by the confluence of the two cells, but 

 by the total abortion of one of the ordinary lobes, the other and 

 more external one assuming a crescent form, by its unrestrained 

 development around a large globular pollen receptacle. We see 

 a very close approximation to this irregularity in Brovcallia^ 

 where one of the anther-cells is much smaller and often very 

 minute, always sterile, and void of pollen, while the other is re- 

 niform as in Anthotroche^ In Brunsfelsia there is an evident 

 confluence of two cells in a rcuiform shape, but in Franciscea 

 there is a total abortion of one of the cells, and its curvature in 

 a crescent form, as in Anthotroche. 



For reasons assigned in another place, I have excluded A, albi- 

 cans and scabrella, and added two that are new, making in all 

 six species belonging to this genus, which are all found on the 

 S.W. coast of Australia, between Swan River and King George's 

 Sound. From an examination of these species I have found it 

 necessary to modify, in the following manner, the character of 

 this genus.
