320 TJie Flowering Plants of Western India. 



first four, each divided into several subtribes, are hero represented. 

 I have thought it better to give the distinctions of these tribes, 

 though confessing that I myself know little about the pollinia, 

 which form so great a part of these descriptions. 



TRIBE 1. EPIDENDRE^. All here given are Epiphytes 

 (except Microstylis, and perhaps Liparis). Anther cells dis- 

 tinct and parallel, pollinia waxy, one to nine in each cell, or 

 those of each cell held together by a viscid appendage. 



1. OBERONIA. Tufted : leaves distichous, sword-shaped, 

 flowers very minute in dense spikes or racemes, sepals broad, 

 ovate or oblong, petals smaller, lip sessile, concave, column 

 very short. 



Note. " Tufted " is used of stems when very short, close, and 

 many from the same root. 



2. MICROSTYLIS. Terrestrial : flowers small in terminal 

 racemes ; sepals and petals about the same length ; lip united 

 to the base of the column, usually flat. 



3. DENDROBIUM. Stems elongate or pseudo-bulbous ; flowers 

 racemose, often large and handsome, sepals about equal, the 

 lateral obliquely united to the foot of the column, lip contracted 

 at the base, similarly united, column short. 



4. ERIA. Flowers not large or bright-coloured, sepals free, 

 lip sessile on the foot of the column, spur various. 



5. PHAJUS. Large stout herbs, leaves pleated, flowers 

 large, handsome, racemed, sepals and petals about equal, lip 

 embracing the column, erect, column long and stout. 



TRIBE 2. YANDEX. Epiphytes (except Eulophia and 

 Geodorum) ; anther cells generally confluent, pollinia waxy, 

 usually 2 or 4 in superposed pairs, attached to a gland or 

 process. 



6. EULOPHIA. Terrestrial smooth herbs, leaves pleated, 

 scape usually leafless, flowers racemose, sepals and petals free, 

 spreading, lip erect from the base of the column, its disk 

 crested or softly spinous, top of the column oblique, entire. 



7. CYMBIDIUM. Generally epiphytes, scape loosely 

 sheathed, flowers in racemes often large, sepals and petals 

 about equal, free, lip embracing the column upwards, middle 

 lobe recurved, column long. 



8. KHYNCOSTYLIS. Stem stout, leafy, leaves very thick, 

 linear, 2-lobed ; flowers in long dense drooping racemes, sepals 

 and petals spreading, lip produced into a broad dilated limb, 

 without side lobes, column short and stout.
