104 Mr. Brown’s Observations on the 
Sobreya of the Flora Peruviana, it appears evident that this genus 
is reducible to Meyera. Enhydra of Loureiro's Flora cochinchi- 
nensis, though described somewhat differently, and referred to 
Polygamia segregata, 1 have little doubt, belongs to the same 
genus; as does unquestionably Hingstha of Roxburgh's unpub- 
lished Flora Indica, where it is also referred to Polygamia segre- 
gata. This plant, which I have examined, is scarcely distinct 
from a species of Meyera that grows in New South Wales. 
- Cryphiospermum of Mons. de Beauvois's interestin g Flore d'Oware 
et Benin, although reduced by him to Cichoracez, I have but 
little hesitation in referring also to Meyera. And lastly, Cesulia 
radicans of Willdenow, likewise a native of æquinoctial Africa, is 
perhaps not specifically different from Cryphiospermum repens of 
Mons. de Beauvois, . - eats 
. MELAMPODIUM 
was established by Linneus, in the first edition of Genera Plan- 
tarum and in Hortus Cliffortianus, from a specimen found by 
Houston near Vera Cruz, and communicated by Miller to Clif- 
ford, in whose Herbarium, now forming part of the collection 
of Sir Joseph Banks, it still exists. It does not appear that this 
plant has been found by any other botanist than Houston ; and 
according to the character given by Linneus of Melampodium, it 
must be considered the only species of the genus. | 
. In the second edition of Species Plantarum he added to it, 
but with a doubt, Me/ampodium australe, a plant adopted from 
Leefling, according to whose description the pappus and surface | 
of the seed are widely different from those of the original species. 
Swartz has referred to the genus a third species, M. humile, en- 
tirely distinct in these respects from both the former; and more 
recently a fourth species, M. dongifolium, with seeds differently: 
modified from all the others, has been annexed to it. | E
