A magnificent orchid, from the great length of its many- 
flowered raceme, which attains three feet, its large flowers 
and their colour, which is a clearer yellow than any of 
the ‘genus hitherto described except A. chrysantha. 
Lindley regarded it as nearest to A. Banksti, from which 
it differs in its more concave hypochile, with the tooth 
hot warted at the base, in its remarkably warted epichile, 
its long column, and other characters. It is a native 
of Tulialba in Costa Rica, whence it was sent by the late Mr. 
Skinner in 1849 to the Royal Horticultural Society. Under 
eddemannia Pescatoret, Plate 7123, I made some obser- 
vations on that genus, and on Peristeria and Acineta and 
their allies, in which I have stated that the latter genus 1s 
distinguished by its short thick column; but this charac- 
ter must, I fear, be given up as distinctive, for the column 
Of A. densa is ag long and hardly more stout than that of 
the above cited Lueddemannia, as a comparison of the two 
gures will show. The fact is that the columns are not
