Corybas laceratus is most closely allied to C. Merrill, 
the only other species known to occur in the Philippines, 
from which it may be easily distinguished by the 3-lobed 
lip as well as by the lacerations on the lip. 
A collection from Burgos, Llocos Norte Province, 
Luzon, July 29, 1918, Ramos 32880, may be this species 
but the flowers are agglutinated and certain determina- 
tion is not possible. 
Aglossorrhyncha Schitr. 
This genus now may be added to the known genera 
of Philippine orchids. The specimen on which the record 
is based bears only one flower, and that one is not com- 
plete. The plant is apparently an undescribed species but 
cannot be described on the basis of the available material. 
Bono: on the trunk [of a tree] in the forest, Demyao (Dimiao?), 
flowers yellow, alt. 1000 ft., September 21, 1923, Ramos s.n.
