Hight years ago a figure of Dipodiwm paludosum, Reichb. 
f., appeared in the Magazine (tab. 7464), and the peculiarities 
of the genus were described, and its distribution given. 
There are leafless and leafy species, as the genus is 
defined in Bentham and Hooker’s ‘‘ Genera Plantarum ;” 
and the leafy species are remarkable amongst orchids 
having distichous, sessile leaves, for the disarticulation in 
the blade between two and three inches above their in- 
sertion. Herbarium specimens have the appearance of 
the leaves being clipped off, with the exception of a few of 
the upper ones. In living plants the position where 
disarticulation will take place is easily seen, as the leaf is 
of a darker green below than above the point. 
Records are not very precise, but from the incomplete
