DESCRIPTIVE LIST. 371 



A species resembling Phalcznopsis Luddemannia in 

 growth, but with pointed leaves very bright green. 

 Flowers on a short spike, yellowish white, barred with 

 broad streaks of rich reddish brown ; lip white, with 

 orange spots, and four lines of violet or lilac. 



These plants should be grown in the East Indian 

 house, with liberal waterings during growth, and even in 

 winter they should be kept damp at the roots. They may 

 be grown in pots, with sphagnum moss, but appear to 

 much better advantage on blocks or in baskets, in which 

 they thrive equally well, only requiring more attention to 

 keep them from becoming dry. They should be hung 

 near the glass. The flowers are produced on a slender, 

 flexible stalk, which continues to grow and produce flow- 

 ers ; but after two months it is well to cut off the flower- 

 stalk, unless the plant is very strong, as the plant will 

 exhaust itself. These plants are very difficult to increase. 

 If they send out young shoots they should be left on the 

 plant till they make roots, when they may be removed. 

 Plants may be produced by bending down the flower- 

 stalk upon the block, covering each node with moss, first 

 cutting off the end of the shoot. Phalanopsis Ludde- 

 mannia produces young plants on the flower-stalk more 

 freely than any other species. The growing season of 

 all is from March to October. 



" Phalanopsids are interesting from the ease with which 

 the flowers may be artificially fertilized, and from the cu- 

 rious phenomena which attend the reception of the pol- 

 linia by the stigmatic cavity. Before the pollinia are com- 

 municated the cavity gapes widely ; in the course of a 

 few hours the sides draw together, and eventually the
