probably not different from the plant found by the late 

 Dr. Anderson of St. Vincent on the banks of the Esseque- 

 bo, and cultivated in some of the gardens under his name 

 of Bignonia Jilicifolia, are easily distinguished from the 

 three species already mentioned, by their rhomboidal leaf- 

 lets, and from each other by differences in the surface of 

 corolla., which is silky in I. bakamensis and smooth in J. 

 rhombifolia. 



I. 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 ascertained 

 that the antherae are dimidiate, with a hardly visible rudi- 

 ment of a second lobe ; a structure which M. Meyer (1. c.) 

 has expressed by ec Antherae simplices," and introduced into 

 his character of the genus. But in an undescribed species 

 lately found in Brazil (J. tomentosa Nob.) they are perfect, 

 consisting of two equal divaricate lobes, as in the greater 

 part of the natural order. This species differs indeed from 

 the rest of the genus in its leaves having constantly a ter- 

 minal pinna. It agrees with them, however, in all the 

 other characters of the flower, and entirely in the structure 

 of its fruit ; it can therefore be regarded as forming only 

 a section of a strictly natural and well defined genus, still 

 depending on characters not materially different from those 

 proposed for it by M. de Jussieu ; the only doubtful species 

 being the Jacaranda 2, of Piso, from which the generic 

 name was adopted." Brown. 



For the above elaborate account of the genus Jacaranda 

 and its known species, which we doubt not will be highly 

 acceptable to the botanical world ; we are indebted to our 

 friend Mr. Robert Brown. 



Our drawing was made in April last, from a fine plant 

 that flowered, probably for the first time in this country, 

 in the grand collection of the Count de Vandes, at Bayes- 

 water. Native of tropical South America, and requires to 

 be kept in the stove. 



The outline figures shew, 1. the stamens with the remarkable barren 

 mament, 2. the germen, style and calyx.
