ON THE GENERA ANADYOMENE AND MICRODICTYON. 41 
Plants’ used it for his two subtribes of 4rethusee. I am inclined to 
re-establish Blume's Zpiphanes, which differs in habit from Gastrodia 
sesamoides, R. Br., as figured in Hooker's ‘Tasmanian Flora) T 
fruit, too, seem to be different, though those of the Australian plant 
are only insufficiently known. Gastrodia is said to be epiphytical, 
whilst Epiphanes is certainly terrestrial. 
I must leave it an open question whether G. Javanica, Lindl., and 
G. Hasseltii, Bl:, are distinct species or not, not having that part of 
Blume’s work to refer to. According to the diagnosis in Miq. Fl. Ind. 
Bat., however, the Griffithian plant should be referred to G. Hasseltii, 
this having a rugulous crista. The characters of the more or less acu- 
minate sepals appear of doubtful importance, our Bengal plants having 
them both acute and obtuse. Thwaites refers his Ceylon plant to 
G. Javanica, and I think correctly. 
If Epiphanes should be incorporated with Gastrodia, the sections 
would be better defined by relying upon the situation of the stigma 
rather than the labellum, as Professor Miquel has done. 
Highly interesting are the pedicels of D. pallens. Originally they 
are only 2—6 lin. long, but when the fruit becomes fully ripe, they 
elongate and are often twice as long as the whole plant. I measured 
one more than a foot long and rather thicker than the scape. The 
bracts vary much, and they are largest in the smaller plants. 
he plant varies in height from 2 to 10 inches; and if my identifica- 
tion of G. Javanica and Hasseltit proves correct, it ranges over Java, 
Bengal, Ceylon, and Coorg.

The subject of this paper has interested me for nearly half a century. 
I was so struck with the figure of the genus in Lamouroux's work, that 
I was very anxious to be able to examine it My late dear friend
