tinues in perfection a long time, and is best grown in a pot

0, macrantlimn. — This splendid Onddium is a great aqui-

 green leaves ; spike several feet long, twining, branching,

 sepals and petals very round and broad, thick and fleshy, rich 

 yellow, tinged with purphsh brown ; lip hastate, much smaller,
