to be slightly larger. In other respects the two are alike. The minuter reticulations 
on the hyaline membrane which covers the pseudo-bulbs are not visible while the plant 
is fresh; they become so only after the pseudo-bulbs have become dry. There are, 
ары sometimes а few radiating and some reticulate nerves which are visible even 
on fresh pseudo-bulbs.

19. Eria, Lindl. 
Epiphytal; usually pseudo-bulbous, the pseudo-bulbs often elongated and stem-like, 
Flowers never large, rarely brightly coloured, often pubescent or tomentose, in racemes 
spikes ог heads, or оп 1- to 2-flowered pedicels, Sepals free, adnate to the 
elongate foot of the column and with it forming a short or long and spur-like or 
saccate mentum. Jip sessile on the foot of the column and incumbent. Column short 
and straight, or long and little curved. Anther imperfectly 4- or 8-celled, Pollinia 8, 
pyriform or broadly obovoid, attached in fours by their bases to a granular membrane, 
or the whole occasionally attached to a single viscus, 
A polymorphous genus comprising about 160 species, all tropical Asiatic. It is separated from 
Dendrobium really by the single character of having 8 pollinia instead of 4. We have maintained 
most of the sections adopted by Sir Joseph Hooker in his Flora of British India, but we have not 
arranged them in the same sequence. Sir Joseph's section Porpaz we have restored to generic rank; 
and for Eria discolor we have restored, as suggested by Sir Joseph himself, the Blumean genus 
Tylostytis, We have reduced the genus Trichosma, Lindl. to Eria, as had at one time been suggested 
by Lindley himself
