BOLLEA. 



There are only two species at present described belonging 

 to this genus ; the growth is very similar to that of a Pes- 

 catorea, but the flower is totally distinct ; they succeed well 

 in the cool-house in a mixture of peat and moss ; they require 

 a good supply of water during the time of growth. 



B. Lalindd. — A very distinct plant of recent introduction. 

 The colour of the flower is bright violet, the inferior halves 

 of the lateral sepals are brownish purple, lip deep orange, 

 column purple. Native of New Grenada. 



B. Patinii. — This species was discovered by my collector, 

 M. Patin, in New Grenada. Sepals and petals pallid blue, 

 tip of upper sepal and inferior halves of lateral sepal yellow 

 like the lip ; the throat is light violet. 



Brassavola. 



There are several species of this genus, but only a few that 

 are sufiiciently showy to be worth growing by the majority of 

 amateurs. They are of easy culture, and grow best in a little 

 moss on blocks of wood suspended from the roof ; a liberal 

 quantity of water is necessary during the growing season, but 

 afterwards much less will suffice. They are best grown in 

 the warmest house, and are propagated by dividing the 

 plants. 



B. acaulis. — A very interesting species from Central America, 

 with rush-like foliage, and a compact habit of growth. Flowers 

 large, sepals and petals long, narrow, and greenish on creamy 

 white lip, large heart shaped and pure white base of tube
