spur arched obtuse shorter than the limb ; petals erect oblong 

 somewhat truncate, the outer and upper angle produced into a 

 filiform spreading process 1'1-1'5 cm. long; hypochil of the lip 

 concave, mesochil roundish convex ; epichil filiform pendulous 

 1*2-1'5 cm. long; rostellum remarkable in the genus, rather 

 large erect 3-lobed, lobes linear-subulate acute, the side ones 

 incurved, the intermediate erect. 



Described and drawn from several living specimens kindly 

 sent to me from Piquetberg by Mr. Schlechter, the discoverer, 

 and hitherto the only collector of the species. Colour of the 

 flowers greenish yellow, with purple spots on the lip and on the 

 tips of the petals, the long filiform processes of the lip and petals 

 dark purple. A very distinct and curious species, as remarkable 

 for its much developed rostellum as for its peculiar petals and 

 lip. — Since the first part of this work was published I have 

 judged it better to maintain the genus Schizodium as distinct 

 from Disa on account of its peculiar habit and lip. Plates 

 33 and 34, therefore, representing Schizodiums under the names 

 of Disa torta, Sivartz, and Disa clavigera, Bolus, must be taken 

 as figures of Schizodium arcuatum, Lindley, and S. hifidum, 

 Reichenbach fil.f respectively.
