PHALAENOPSIS Blume 
PHALAENOPSIS MARIAE Burbidge. 
This endemic species has been collected both in Luzon and Mindanao 
and is readily distinguished from P. Lueddemanniana by its many flowered 
elongated inflorescence. The scape equals or exceeds the leaves and the 
flowers are smaller than in P. Lueddemanniana. R. C. McGregor described 
the flowers of specimens gathered by him in Luzon as follows : "88 blossoms 
all open on one plant, Fl. stalk with 8 to 15 blossoms, petals pale-yellow 
with heavy spots tending to bars of burnt-carmine. Central part mostly 
violet-purple, upper part of center white with two dots of yellow,"
