80833 Quisumbing, August 25, 1930. The living plants were 
collected from the mountains between Siain and Atimonan, Ta- 
yabas Province, growing at medium altitudes on tree trunks. 
They thrive best in wooden baskets. The flowers are marguerite 
yellow 2 except the purple marginal wings of the column. 
This species is manifestly allied to Agrostophyllum malindan- 
gense Ames, which it closely resembles in vegetative characters. 
It differs notably in its leaf sheaths not being inflated and ex¬ 
panded, particularly at the apical portion of the stem, its in¬ 
florescences not being densely capitate, and in having much 
larger flowers and differently shaped flower parts. 
In the herbarium of Oakes Ames are two plants, with mature 
flowers, that must be referred to this species. The data are 
Nueva Vizcaya Province, Luzon, J. de Veyra, September 25, 
1916, and the plants are said to be tufted and epiphytic.
