The scape is about one foot in height, covered at the base with 

 loose membranous sheaths ; the lower ones ovate, those on the 

 higher portions of the scape more pointed. The leaves appear 

 to be terete, but in the only specimen which I have seen are in 

 bad condition ; the largest is 5 inches long. The flowers are 

 rather bigger than those of E. scripta and open wide. The 

 narrow linear-lanceolate acuminate bracts are half the length of 

 the ovary. The petals and sepals are curiously veined in a reti- 

 culate manner; the former are a little shorter and considerably 

 broader than the latter, but the difference is hardly sufficiently 

 marked to cause me to refer it to the genus Lissochilus. The 

 central lobe of the lip is large in proportion to the rest, and 

 decorated with 7 crests or raised notched ridges. The pollinia 

 are more circular in outline than usual ; each has a semilunar 

 depression at the back. 



Lissochilus. 

 Only two species of this African genus have as yet been met 

 with in Madagascar, and none are known from the other islands 

 of the archipelago. I have seen neither of the species which 

 were collected by Eutenberg and described by Dr. Kranzlin under 

 the names of L. madagascariensis and L. Butenbergianus in the 

 Verhandl. Bremen, yii. pp. 256, 257. 



Ctrtopodium. 



This genus is represented by a single species, occurring in all 

 the larger of the Mascarene Islands The remaining species of 

 the genus are scattered over the tropica of America, Africa, and 

 Indo-Malaya.
