minuti, rubidio-brunnei. Sepala lateralia cum sacco labelli cohas- 

 rentia, oblongi-triangularia, acuta, 2 mm. longa, circiter .5 mm. 

 lata, porrecta. Sepalum dorsale oblongum, obtusum, erectum, 1.5 

 cm. longum, 1 mm. latum, ad basim subito attenuatum. Petala 

 oblonga, subquadrata, obtusa, circiter 1.25 mm. longa, .75 mm. 

 lata, incurva. Labellum valde saccatum, leviter complanatum, 

 utriculosum; lobi laterales obsoleti; lobus medius triangulus, 

 minutus, incur vus, valde acutum, profunde excavatus, sub apicem 

 pariete antico sacci subtiliter protumido. Saccus obtusus laterali- 

 ter complanatus, quam ovarium longior. Gynostemium breve; 

 rostellum in basi gynostemii elongatum, alte bipartitum, laciniis 

 ad apicem dilatatis. Pollinia 4 in corpuscula 2 subglobosa unita, 

 stipite lineari 1.5 mm. longo, ad apicem dilatato, glandula magna, 

 ligulato-oblonga. Anthera valde rostrata. 



At first glance this species bears a striking resemblance to 

 Schcenorchis minimiflora (Hook, f.), from which it differs in the 

 excavated, not terete, middle lobe of the labellum. In comparing 

 the two species one might almost suppose that the details of the 

 labellum and rostellum were inaccurately interpreted as illus- 

 trated in Hooker's Icones. Hooker's figure does not show the 

 attachment of the lateral sepals to the sac of the labellum, nor 

 does it make clear that the petals are wider than the lateral 

 sepals. In S. philippinensis the middle lobe of the labellum is 

 deeply excavated so that the erect point resembles the lip of a 

 pitcher.
