even at this season, retain all their brilliancy for several 

 weeks. It may be grown on a block or in a pot, but on

 of Guatemala. 



0. chrijsotJiyrsus. — This ver}' showy and free- flowering 

 Oncidium is a native of Brazil. It is free and compact in 

 its gi'owth, seldom growing more than a foot high, and pro- 

 ducing from the pseudobulb, when fully developed, a fine 

 branching spike some three feet in length, covered with its 

 lovely flowers ; sepals and petals green, streaked with red ; 

 the lip is large and bright yellow. It succeeds well upon a 

 block, and remains in bloom a long time. I saw a few fine

0. cojviigenim. — This plant bids fair to become highly
