Negros, Mount Silay (1536 Whitford) May, 1906, alt. 1,000 m. 
This species was determined by Copeland as Cyathea Christii, but it is 
distinguished from the latter by its axial parts being richly covered with 
furfuraceous scales, by the cost* being covered with rounded inflated scales, by 
its membranous texture and very reduced size.
