thouglit it useful even in this stage of tlieir appearance 

 to refer to tliem by their name. 



Vebnonia is the chief type of the Vemoniefe of M. 

 Cassinij and is technically distinguished from its nearest 

 genera, by a double seedcrown, the inner rank of which is 

 capillary, the outer short and laminar. The genus is di- 

 vided by the above botanist into three fractions termed by 

 him subgenera; 1. Vernonia proper, where the interior 

 leaflets of the calyx are surmounted by a subulate (awl- 

 shaped) spinescent appendage: 2. Ascaricida, where these 

 are terminated by a broad foliaceous subspatulate ap- 

 pendage: 3. Lepidaploa, where they have no appendage 

 at all. 



Our plant agreeing in every respect with the short record 

 of Vernonfa sericea, except that the flower is purple, and 

 not white, as it is stated to be in that ; we have not deemed 

 it expedient to separate the two, especially as we know the 

 colour of the flower to have been judged of by M. Richard 

 from a dried sample. 



(jS) comes exceedingly near to Vernonia arborescens 

 (Convza arborescens. Hort. Kew. ed. 2. 5. 30,), from which 

 it appeal's to diffier only by having longer narrower leaves 

 with a silky haired fur. 



The drawing was made from a plant which flowered 

 last December in the hothouse at the nursery of Messrs. 

 Colvill, in the King's Road, Chelsea. It is supposed to 

 have been derived from the Brazils, or possibly Guiana, 

 like the plant of M. Richard.
