Jacaranda ovalifolia is very nearly related both to /. 

 acutifolia and /. obtusifolia of Humboldt and Bonpland 

 {Plant. j3<]quinoet. tabs. 17 and 1 8), between which it may be 

 placed. /. acutifolia differs from it chiefly in all the leaf- 

 lets being lanceolate, and in having a smaller number of 

 pinnae. /. obtusifolia is still more distinct in its leaflets 

 entirely wanting the mucro, which is both obvious and 

 constant in our plant, and in having a smooth corolla. /. 

 BaJiamensis, Nob. (/. caroliniana, Persoon ; Bignonia c<Bru- 

 lea, Linn.), of which there is in the Banksian Herbarium a 

 single imperfect specimen that may be supposed to be 

 authentic, and /. rliombifolia, of Meyer [Flor. Essequeb., 

 213), which is probably not different from the plant found 

 by the late Dr. Anderson, of St. Vincent, on the banks of 

 the Essequebo, and cultivated in some of the gardens, 

 under his name of Bignonia filicifolia, are easily distin- 

 guished from the three species already mentioned, by their 

 rhomboidal leaflets,- and from each other by differences in 

 the surface of corolla, which is silky in /. Bahamensis and 

 smooth in /. rhombifolia. 



J. procera. Nob. {Bignonia Copaia, Aublet, B. procera, 

 Willd.), is sufficiently different from all the others in the 

 much greater size of its leaflets, which are frequently up- 

 wards of an inch in length ; in the rachis of the pinnae not 

 being winged ; and in the cylindrical calyx, of which the 

 teeth are extremely minute. 



In five of the above-mentioned species, I have ascer- 

 tained that the antherae are dimidiate, with a hardly visible 

 rudiment of a second lobe ; a structure which M. Meyer 

 (]. c.) has expressed by " Antherae simplices," and intro-
