DESCRIPTIVE LIST. 341 



All are evergreen, and produce the flower-stems from 

 the base of the pseudo-bulbs. Some of the species, such 

 as Odontoglossum gtande, Insleayi, citrosmum, Phalcenopsis, 

 pulchellum, will grow well in any intermediate or Mexican 

 Orchid house. Most of the species do best in pots, with 

 peat and moss, with good drainage. The small-growing 

 kinds, such as O. Ehrenbergii, do well on blocks. Some 

 of the tall growers require a good peat soil, but all soil 

 must be fresh and sweet. They must never be allowed 

 to dry up, but water must at all times be given judi- 

 ciously. 



Recent years have added to the genus (in 1833 there 

 were but five known species), and every year gives us 

 new discoveries ; latterly it would seem as if each new- 

 comer was more beautiful than any we had before known. 

 To attain success in the culture of this beautiful genus 

 of plants is worth any labor, which will be well repaid 

 by the stately grandeur of some of the species, the deli- 

 cate beauty and the charming fragrance of others.
