produced from the side of the bulbs on long drooping spikes. 

 They are best grown in pots, with rough fibrous peat and good 

 drainage, and require a liberal supply of water at the roots in 

 the growing season ; afterwards, just enough water to keep 

 their bulbs plump will suffice, for they should never be allowed 

 to shrivel. They are propagated by dividing the plants when 

 they begin to gi'ow. 



B. Gireoudiana. — A very handsome species of a genus 

 that is rather neglected by Orchid-growers ; it is a plant of 

 easy culture and good robust habit ; bulbs stout, and with the 

 leaves of a light green colour. It produces spikes of large 

 bright yellow flowers spotted with red. Native of Costa Rica. 



B. Lanceana. — A free-flowering Orchid from Demerara, 

 blooming at difi'erent times of the year, and bearing yellow

 than the other, having larger and brighter coloured flowers.

 blooming abundantly from June to August. The colour of the

 the species, the sepals being very much lengthened out ; they 

 are greenish white spotted with dark brown ; the lip is also very 

 much lengthened, and is yellowish dotted with purple. It is 

 deserving a place in every collection.
