Eria mindanaensis sp. nov. 



Herba epiphytica, caespitosa. Caules foliosi, ± 6 dm. alti, 

 internodii circiter 5 cm. longi, vaginae complanatae. Folia 

 oblongi-lanceolata, coriacea, acuminata, acuta, usque ad 1,7 dm. 

 longa, circiter 2.5 cm. lata. Racemi 2, usque ad 2.5 dm. longi ad 

 summum caulium orti, graciles viride, rhachidi pubescente. Brac- 

 teae inflorescentiae retroflexae, lineares, acuminatae, valde acutae, 

 viridae, ± 6 mm. longae. Pedicellus cum ovario 5 — 8 mm. longus. 

 Sepala extus pubescentia, lateralia, ± 4 mm. longa, late ovata, 

 , asymmetrica, obtusa, dorsale valde cucullatum, circiter 4 mm. 

 longum. Petala oblanceolata, obtusa. 3-nervia, 3.5 — 4 mm.

The shorter bracts, the apical and much larger callus, the 

 broader leaves and longer racemes distinguish this species from 

 E. davaensis Ames, its nearest ally. The terminal callus is quite 

 remarkable on account of its extraordinary size and passes into a 

 central keel which extends to the base of the lip.
