 — This species is named for Firmin Lambeau, of Brussels, and was produced by A. A. Peeters 

 & Sons, from a cross made in 1904 between Laeliocattleya Ceres (Cattleya Mossiae X Laelio- 

 cattleya Phoeba) , a yellow variety, and Cattleya Dowiana aurea. Two forms differing in color 

 from the original are also known. L. Firmini ardens, shown at London in 1913, has the floral 

 divisions, copper red instead of apricot yellow, whereas L. Firmini Mqssange, named for 

 Leon Massange by Peeters in 1913, is reddish saffron. The several varieties are the same in 

 form of flower and in character of the lip. — E. J. Kraus.

 1920.— A brief description of this species from the viewpoint of using it as an ornamental is 

 given. It is recommended because of its hardiness and the abundance of fragrant blossoms 

 it produces very early in the spring. It might even be utilized as a pot-plant for house 

 decoration, provided some leafy plant were grown with it to produce the foliage effect.—
