D. aggregatum, var. majus. — As the name implies, 

 this is a larger form than 

 the type. The pseudo-hulhs 

 form dense clusters ; they 

 are stout, some four inches 

 high, and bear on the sum- 

 mit a solitary thick and deep 

 green leaf ; racemes longer 

 than the growth, bearing 

 numerous large flowers of a 

 uniform clear yellow. It 

 thrives best upon a block. 

 Spring months. Northern 

 India. 



B. Ainsworthii. — This is 

 a hybrid raised in the gar- 

 dens of Dr. Ainsworth, of 

 Manchester. The parents 

 were S. keterooarpum and D. 

 nobile. In habit of growth 

 it resembles the last-named 

 parent, but is even more 

 floriferous, and must take 

 rank as one of the finest of 

 the family. Sepals and 

 petals pure white ; ground- 

 colour of lip white, bearing 

 a large central blotch of 

 rich amaranth, feathered at 

 the edges. Another form 

 called D. Ainsworthii ptir- 

 vureum, from the same batch 

 of seedlings, is distinguished 

 by its intense rich purple 

 lip. February and March.
