ODONTOGLOSSUM LUTEO-PURPXJRETJM (RADIATUM). 



0. lyroglossum, Echb.f. — This very fine species is in the 

 way of 0. Wilckeanum, but differs in colour. The pseudo- 

 bulbs are oblong ovate, compressed, diphyllous ; its leaves 

 are oblong ligulate, and its radical scape bears a vigorous 

 raceme, the individual flowers of which are about four inches 

 across. The sepals and petals are oblong lanceolate, coarsely 

 toothed at the edges, of a bright yellow heavily blotched with 

 chestnut brown ; the lip is small, much fringed and toothed, 

 similar in shape to that of 0. luteo-purpureum, yellow with a 

 large blotch of chestnut brown in the centre. The plant is 

 supposed to be a natural hybrid between 0. Pescatorei and 

 0. luteo-purpureum. — New Grenada.
