Pseiidobulbis foliisque Oncidio amplialo similibus, scapis radicali- 

 bus cum floris squamis acuminalis subpaleaceis slriatis suprema ovarii 

 longiludine adpressa, sepalis lanceolafis menlo obluso, petalis linearibus 

 paullo brevioribus apice abrupte seligeris, labello oblongo trilobo pilosa 

 lacinia media oblonga emarginala crispa lateralibus brevibus oblusis 

 appendice ovata in medio, clinandrio fimbriato. 



La Guayra. Leaves and pseudobulbs I have nol spen. Flowers which grew single 

 on scaly scapes, lilte Maxillaria picta , are pale vellow , slightly linged wiih pinlt on 

 Ihe otilside. The petals nre almost exactly linear , terminating suddenly nt ihe point 

 in a fiiie bristle. Tlie lip is for ihe most part white with a few scattered hairs over 

 all its upper surface; ihe centre of ihe upper pait is yellow, ihe sides of ihe lower 

 parl are streaked with crirason veins. The anlherbed is bordered by a fine fringe. 

 In many respects this approaches Maxillaria splendens, which however is easely 

 known by its long grassy leaves.
