Dr. B. Seemann on the Bignoniacese. 29 



viz. one immediately below the base and extending nearly to the 

 middle, the other just below the middle; the two outer spots 

 are generally elongate, and sometimes form a submarginal vitta, 

 interrupted in its middle. 



V. — Revision of the Natural Order Bignoniacese. 

 By Berthold Seemann, Ph.D., F.L.S. 



Before proceeding to publish the results of my examination of 

 Bignoniacese, I shall give a list of all the genera I hold to be 

 true members of the order. They will have to be grouped very 

 differently when the whole of them shall have been subjected to 

 closer investigation, and a number of new ones added. The two 

 tribes Eubignoniese and Catalpese, founded upon important 

 carpological characters, must stand, and a third one (Jacarandese) 

 be added to them. 



I. Eubignoniece, having a marginicidal fruit, and a septum 

 placed parallel with the direction of the valves of the capsule. 



II. Cat alp ea, having a loculicidal fruit, and a septum placed 

 contrary to the direction of the valves of the capsule. 



III. Jacarandece, having a marginicidal fruit, and a septum 

 placed contrary to the direction of the valves of the capsule. 



From the subjoined it will be seen that all cirrhose Bigno- 

 niacese are confined to America, and that, with only one excep- 

 tion {Dolichandra), they are Eubignoniese; again, that, with 

 the exception of two Asiatic genera (Millingtonia and Calos- 

 anthes) all the ei*ect Bignoniacese belong to Catalpese and Jaca- 

 randese.
