thought it useful even in this stage of their appearance 
to refer to them by their name. 
Vernonia is the chief type of the Vernoniew of M. 
Cassini, 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. VERNonrA proper,. where the interior 
leaflets of the calyx are surmounted by a subulate (awl- 
shaped) spinescent appendage: 2. Ascaricipa, where these 
are terminated by. a broad foliaceous subspatulate ap- 
pendage: 3. Leripapioa, where they have no appendage 
_at all. . 
- Our plant agreeing in every respect with the short record 
of VerNonta 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. 
_ (8) comes exceedingly near to VERNoNIA arborescens 
(Conyza arborescens. Hort. Kew. ed. 2. 5. 30.), from which 
it appears to differ 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.
