SILVA OF NORTH AMERICA. 
ROSACEA, 
River Junction, Florida, and on the sand hills of Summerville west of the city of Augusta, Georgia. 
According to Aiton it was cultivated in London in 1758 by Philip Miller.’ 
1 Aiton’s specimen of Crategus flava is in the British Museum, 
and although it was made some time after the petals had fallen, it 
evidently represents the plant which now grows at River Junction 
and Augusta. Eighty years ago this species was cultivated in Eu- 
rope, as specimens of cultivated plants in different herbaria show, 
but I can find no indication of its existence now in any of the Eu- 
ropean collections of living plants which I have examined. The 
Crategus flava of authors later than Aiton may be his species, but 
it is impossible to judge of this from their descriptions. The Cra- 
tegus flava of Lindley (Bot. Reg. xxiii. t. 1939) is evidently not 
Aiton’s species, and is probably the same plant as his Crategus flava, 
var. lobata (1. c. t. 1932). This plant, which is not now known to me 
in a wild state, is still cultivated in the Royal Gardens at Kew. It 
differs from Crategus flava in its ten stamens and pear-shaped hard 
green fruits which do not fall until January or February. It is 
probably this plant which was figured by Loudon as Crategus flava. 
The plant figured for Crategus flava in the fourth volume of The 
Silva of North America is Crategus Floridana, Sargent.
