TJrismia.] CXLVII. BURMANNIACE^E. (J. D. Hooker.) 667 



Whole plant 3-1 in. high, very closely allied to T. Brunoniana, but differing in 

 the solitary flower and orbicular perianth-lobes. 



ORDER CXLYIII. ORCHXDEJE. 



Herbs of various habit, rarely shrubby, of two principal forms : 1, 

 terrestrial, tuberous-rooted herbs, with annual herbaceous simple stems 

 and solitary or spicate or racemose flowers ; 2, epiphytes with perennial 

 stems or branches variously thickened and forming a pseudobulb, flowering 

 from the top sides.or baserof the pseudobulb. Perianth superior, irregular, of 

 6 free or variously combined pieces ; 3 outer (sepals) more or less alike, the 2 

 lateral sometimes united into a short or long sac or spur-like base (mentum) ; 

 3 inner (petals) dissimilar,, the 2 lateral alike, the other (Up} usually very 

 differently shaped. Stamens and style united in a column opposite the lip,

waxy, i-4 in each cell, free, or those of 

 each cell held together at the base by a viscid appendage, not attached by 

 their bases or by a caudicle to the rostellum. (5 Tipularia has caudicled 

 pollinia, and in Calanthe and other C&logynece the long bases of the pollinia 

 resemble caudicles.) 



Subtribe 1. MALAXED. Stems simple, leafy, rarely leafless, with often a 

 pseudobulbous base. Inflorescence terminal. Flowers small or minute. 

 Anther erect or inclined, usually persistent, not incumbent. Pollinia 4 

 (or 8), subequal, close together, usually free (without a viscid appendage). 



Subtribe 2. DENDROBIE^E. Inflorescence terminal, lateral, or on a leafless 

 scape. Pollinia 4, rarely 2, 1 seriate, parallel, appendage 0. 



Subtribe 3. ERTELE. Inflorescence lateral, or on a leafless scape. Pollinia 

 8, subequal, appendage or obscure. 



Subtribe 4. BLETIE^. Inflorescence usually lateral. Pollinia 8, except 

 in Anthogonium, usually in 2 series, parallel, ascending, connected by a 

 granular appendage. 



Subtribe 5. CCELOGYNE&. Inflorescence terminal. Pollinia 8 or 4, sub- 

 equal, connected by viscus or an appendage (in Calanthe and others, the 

 pollinia are appendaged, but the appendage is an undeveloped portion of 

 the pollen itself, and is not derived from the rostellum).
