The plate here given is the reproduction of a coloured dra^ving by 

 the Rev. C. Parish. It resembles in many respects Sarcanthus 

 Pariskiiy Hook. (Bot, Mag. t. 6217), in habit^in the lorate bifid leaves, 

 yellow flowers, spur, and especially the carious pollen; but in that 

 plaut the leaf-lobes are rounded, ilie flowers are larger, the spur 

 horter, there is a distinct midlobe to the lip, the colunrn is longer and 

 narrower, and the spur is septate below the caiddle, and has a large 

 dorsal callus, thus referring it to the genus Sarcanthus. Were it not that 

 Mr. Parish notes that ' there is no apparent j^eptum in the spur,* I 

 should have regarded these two plants as congeneric. The singular 

 structure of the pollinia is repeated with modifications in SaccoJabinm 

 ohtuaifolitim. and actcniinatum (Plates 21o4, 2135), but it is carr.ed 

 (according to Parish's drawing), as it were, further in S. JIavum, ^or 

 each poUeu-mass is broken up into a pair, each pair lias a short stipes, 

 and these unite into a common one that is inserted in the vei'y lung 

 slender flat flexuous main stipes. I need scarcely add that I regard 

 the genus Sarcanthus as separated from Saccolahinm by a purely arti- 

 ficial character; and that a reclassification of the species cf both^ to- 

 gether with those of Cleisostoma^ is to be looked for when better 

 materials are available. — J. D. H.
