Ceratostylis latipetala sp. nov. 
Aff . C. rubrae, speciei quam habitu et stmctura liaec species conspicue ' 
simulat. Planta robusta. Gaulis ramosus. Folia coriacea, rigida, li-

longus. Gynostemium brachiis magnis, rotundatis. 
In habit Ceratostylis latipetala is almost indistinguishable from C. rubra. 
In its flowers, however, it exhibits unmistakable differences from that species. 
The labellum alone will serve as a constant differentiating character. This organ 
is concealed in the sac formed by the coherent lateral sepals. From studies of 
several flowers the labellum appears to vary to a large extent in the nature of 
the ealli. Sometimes they are very conspicuous, at other times difficult to observe. 
As in C. rubra so in C. latipetala the peduncles of the flowers are invested with 
a series of nervose bracts, the outer one forming a closely appressed sheath which 
reaches to the base of the perianth. The ovary is always concealed in the bracts. 
The flowers are described as orange-red. The petals are very characteristic of this 
species and are the broadest yet recorded for the genus.

I refer to this species specimens from Luzon. The plants bear two flower- 
shoots between which the leaves arise after the flowers are expanded. The sepals 
are very fleshy, the lateral ones oblong, acute, strongly falcate, about 2 cm long. 
The petals are oblong-elliptic, obtuse, with raised longitudinal nerves. The 
labellum is 2 cm long, obscurely 3-lobed, blunt and rounded at the apex, where 
there are several conspicuously raised nerves. At the base it is contracted into 
a silicate claw. The outline of the labellum agrees with the figure of E. squalida 
published by J. J. Smith in the second volume of plates which illustrate “Die 
Orchideen von Java” ( Plate CLXV). According to the notes made by Doctor Fox- 
worthy the plants found on Mount Pinatubo grew in very coarse gravelly soil 
where they received the most intense heat of the sun and where they bloomed 
in the latter part of the dry season.
