In habit Ci ■ralosiylis latipetala is almost indistinguishable from C. rubra. 

 In i(s 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 calli. Sometimes they are very conspicuous, at other times difficult to observe. 

 As in V. rubra so in 0. latipetala the peduncles of the flowers are invested with 

 ;i series of nervose bracts, the outer one forming a closely appressed sheath which 

 reaches to the bast' 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 ami are the broadest yet recorded for the genus.

T refer to this species specimens from Luzon. The plants bear two tlower- 

 shoots between which the Leaves arise after the flowers are expanded. The sopals 

 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 sulcate claw. The outline of the labellum agrees with the figure of E. st/ualitla 

 published by •!. J. Smith in the second volume of plates which illustrate "Die 

 Orchideen von -lava"' {Plate CLXV). According to the notes made by Doctor Fox- 

 worthy the plants found on Mount Pinatubo grew in very coarsL' gravelly soil 

 where they received the most intense heat of the sun and where they bloomed 

 in the latter part of the dry season.
