This diminutive plant occurs fparingly in the neigbourhood of London, and principally to the weftwart 
it; we have found it on Hounflow-Heath, Putney, and Barnes-Common, more frequently indeed on the | 
and generally on the edges of gravel-pits, where the foil has been dry and barren, and where ufually gi 
Gnapbalium montanum, Aira flexuofa, and Ornithopus perpufillus. 
Its flowers, which come forth in May and June, are very minute, but when magnified fufficiently difting 
the leading trait in its generic character; they are fucceeded in July by feed-veflels rather large in propot 
to the plant. . | 
The ftalk is not always deftitute of leaves; the more luxuriant the plant, the more it is difpofed to prot 
them: Macwnot obferves, that they are fometimes found entire on the edges.
