margins incurved, a little longer than the sepals ; lip galeate, 

 the limb nearly hemispherical, free apex large obtuse crisped, 

 produced at base into two conical sacs of about 2 mill, long ; 

 rostellum rhomboidal, sharply tridentate with two recesses on 

 the front edge for the reception of the caudicles, gland only one, 

 nearly square, lying upon the rostellum ; stigmatiferous lobe 

 semi-orbicular somewhat concave, cushioned ; ovary 6-ribbed, of 

 which 5 are sharply ridged or almost winged. 



Described from several living and dried specimens. The 

 flowers are rosy with darker carmine tints on the tips of the 

 sepals and petals. In habit and colour of the flowers this 

 resembles S. erectiim, Swartz ; in the shape and setting of the 

 flowers S. memhranaceum, Swartz ; but its peculiar short conical 

 sacs, its single gland, and its almost winged ovary at once 

 distinguish it from these and from any other species. Lindley, 

 adhering literally to an artificial distinction, placed the species 

 in his group Saccatae. But with none of the members of that 

 group has it any other alliance than in its abbreviated spurs, 

 while in other respects it differs widely from them, and I think 

 will be more naturally placed, as an exceptional species, in the 

 spurred group.
