4. THRIXSPERMUM AMPLEXICAULE (Bl.) Reichb. f. Xen. Orch. 2:121. 
This interesting plant which has been ascribed to the Philippines through 
Cuming's collection numbered 2056 belongs to a small group of species 
well characterized by the thickened rhachis of the inflorescence and the 
ephemeral flowers. The ovate-cordate leaves, which at their bases embrace 
the slender stems, are persistent, 2.5 cm apart. The flowers are white and 
deep-purple. The specimens collected by McGregor were found growing 
among grasses in bogs.
