0. vexillarium. — This new and magnificent Orchid ranks 

 among the most beautiful of Odontoglossums. It has been 

 known to science for a long period, but it is only lately that 

 it has been imported in a Hving state, after numerous futile 

 eff'orts. It is a most valuable addition to this class on account 

 of the distinct colour of its flowers. Leaves light gi'een, 

 from eight to ten inches long, and an inch broad. The 

 flower spikes are produced from the sides of the bulbs, and 

 bear from five to seven flowers each ; sepals and petals rosy 

 pink ; lip of the same colour. There are many 

 varieties of this charming species, some much lighter than 

 others. Mr. Richards, gardener to Baron Rothschild, Gun- 

 nersbury, exhibited a splendid specimen at the Royal Horti- 

 cultural Society's Gardens, at South Kensington. Native 

 of New Grenada.
