52. Eria (\Hymeneria) senilis sp.nov. Radices fibratse, ramosa?. 

 Pseudobulbi approximati, uniarticulati, 3.5-4 cm. longi, circiter

 bescentes. Pedicellus cum ovario ± 3 mm. longus, dense albido- 

 tomentosus. Sepala lateralia triangulari-ovata, concava, extus al- 

 bido-pubescentia, 5.5 mm. longa, mentum obtusum formantia. 

 Sepalum dorsale anguste ellipticum, extus albido-pubescens. Pe- 

 tala oblongi-elliptica, obtusa, trinervia, glabra, circiter 5.5 mm.

Eria senilis in general aspect resembles E. ventricosa Leavitt, 

 and is more nearly related to it than to any other Philippine 

 species heretofore described. The strongly saccate labellum with 

 an entire lamina distinguishes it from the older species.
