Herb. 3000 Mrs. K. B. Day, November, 1934. 
The description was based on living specimens given to the 
junior author by Mrs. Day and now cultivated in the Bureau 
of Science orchid house. The flowers have the general ap- 
pearance and habit of opening of Sarcochilus pallidus. Pedi- 
cellate ovary chalcedony yellow; sepals and petals white with 
naphthalene yellow tips; labellum white with the callus on the 
front lobe apricot yellow; column naphthalene yellow. 
The genus Bromheadia is new to the Philippines. Bromheadia 
philippinensis is apparently closely allied to B. alticola Ridl., 
but differs in its apparently dissimilar habit of growth and the 
obtuse outward-pointing side lobes of the lip.
