6.— THE GENERA AND SPECIES. 

 Tribe I . — Epidendrece. 



I. Pleurothallis. — A large genusofinconspicuous plants 

 very common along the banks of the rivers and creeks, 

 growing generally on the smaller branches and even twigs 

 of low trees in the form of cushions or rosettes. They 

 may be recognised by their single leaf, mounted on a 

 short stalk, from the top of which and the base of the 

 leaf, proceed one or more flower spikes. Some of them 

 are very pretty when grown in masses but individually 

 they are hardly showy enough for the orchid fancier. 

 They are however useful to cover the surface of the 

 baskets in which such plants as Cattleyas are grown. 

 Twenty-one species have been recorded : — 



1. P. ciliata ... Flowers brownish yellow, downy. 



2. P. ruscifolia ... Flowers green. 



3. P. pruinosa ... Flowers yellow. 



4. P. Lanceana ... Flowers yellow and crimson. 



5. P. pifta ... Flowers yellow with red stripes. 



6. P. sicaria ... Flowers greenish with purple stripes. 



7. P. aristata ... Flowers purple veined. 



8. P. Grobya ... Flowers yellow and purple. 



9. P. emarginata ... Flowers green and white with a rosy lip.
