the same structure. Fig. 1, which represents a section of 

 the lower part of the flower, explains the peculiarity now ad- 

 verted to. 



The species has been named after Mr. Perrin, Mr. Har- 

 rison's intelligent gardener, under whose care so many fine 

 South American epiphytes have been for the first time brought 

 into flower in this country. 



Like the rest of the genus this requires to be grown in a 

 moist stove, the temperature of which may be kept from 60 

 to 70 degrees of Fahr. in winter, and from 70° to'90°, or even 

 100° with sun heat, in summer. It is propagated, like the 

 other plants of this order, by divisions of the rhizoma, or root- 

 stock, with a stem adhering to them. The soil should consist 

 of good peat, broken, or cut into pieces one inch, or one inch 

 and a half square. The pots should be about half filled with 

 broken bricks, or something of that description, to carry off 

 superfluous water, and if they are plunged in a tan-bed, this 

 will allow the heat to rise more freely than if the pots were 

 wholly filled with soil. It is of the greatest importance to 

 preserve and encourage the roots, and as they are generally 

 protruded near the surface of the soil, it should be raised 

 several inches above the level of the pots, in a pyramidal 

 form, in order that they may have full room to push out.
