 Introduced from the Brazilian province of Kio Grande do Sul by- 

 Mr. William Bull, of Chelsea^ in whose nursery it flowered in 1873. 

 It is nearly allied to the preceding species^ Maxillaria i^ida, differing 

 chiefly in the pseudo-bulbs^ bracts and colour of the flowers, which 

 are as in M. incta very copiously produced. The specific name refers 

 to the purple column.
