 49. Saccolabium, Bl. 



Epiphytes stems short rarely long. Leaves lorate or oblong 

 coriaceous or terete. Racemes or panicles lateral erect or pendulo^^s. 

 Flowers small. Sepals or petals free or adnate to the column base, 

 subequal. Lip sessile at the column base, side lobes short or almost 

 absent, midlobe small. Spur saccate or conic cylindric, with usually 

 a callus on the back in the mouth, and frequently a ridge more or less 

 developed on the lower face, sometimes meeting the opposite wall 

 and dividing the spur into two. Column short footless, arms very 

 short or wanting. Anther ovate usually beaked, pollinia 2 more or 

 less split, caudicle narrow linear, or broad, disc small or large various. 



Species about 200 African, Indian and Malayan, Chinese. 



I am quite unable to keep up the genera Cleisostoma and Sar- 

 canthus based on the development of the calli in the spur, closely 

 allied plants after differing in this point so much as to belong to these 

 different genera. The Calceolare section of Saccolahium, with a 

 saccate spur, the side lobes quite indistinguishable and forming the 

 complete edge of the sac, and 'entire absence of any callus, makes a 

 much more distinct genus. Acampe incorporated in the Flora of 

 British India with Saccolahium as far as the typical species go differs 

 in the lip possessing no real spur at all, and I keep it distinct.
