Epiphronitis Veitchii is a bigeneric hybrid between Epiden- 

 drum radicans and Sophronitis grandiflora that should be 

 included in every collection. It has rich scarlet flowers, and 

 requires cool intermediate house treatment. 



L^LiAS are only distinguished from Cattleyas by the pollen- 

 masses, and, with the exception of L. anceps and the L. autiim?ialis 

 section, all may be cultivated under similar conditions, although 

 L. purpuraia succeeds better when grown a few degrees warmer. 

 L Digbya7ia (Fig. 384) is one of the most distinct Orchids in 

 cultivation. To be successful with L. anceps^ a strong light is 

 absolutely necessary ; it wnll stand, with free ventilation, the full 

 power of the sun's rays. The plant requires an abundance of 

 moisture, with strong heat during the growing season, and must

not be allowed to suffer from want of water until the flower- 

 spikes have been removed, after which a long rest, with a cool 

 temperature and dry atmosphere, is necessary, during which time 

 little moisture is required at the roots. There are many hand- 

 some forms, varying from deep rose -purple to the purest white. 

 They flower through the dead of winter, and are always appre- 

 ciated. Fig. 385 represents L. a. IVaddoftensis, one of the most 

 beautiful of the white section. Fig. 386 shows a fine plant 

 of Z. a. Sajideriana, grown in the Highbury collection of the 

 Right Hon. J. Chamberlain. 



L^lio-Cattleyas are the hybrids derived from intercrossing 

 species of the two genera indicated by the name, and succeed with
