This little plant is allied to M. pusillum, Lindley, a native of 

 the Cape. It has white flowers, accordiug to a drawing made by 

 Deans Cowan. The leaves are £ an inch long and 2 lines across, 

 broader and more flaccid than M. pusillum. The racemes are an 

 inch long, the flowers 2 millim., the capsule 1 line.

A very small-flowered plant, remarkable for its numerous 

 narrow grassy leaves, somewhat like those of an Isochilus with 

 an unequally bilobed apex and crisped margin. The small 

 flowers are laxly arranged on a very slender rhachis. The petals, 

 sepals, and lip are very similar in shape, triangular lanceolate, 

 acuminate, giving the flower a star-shaped appearance. The 

 spur is rather short, straight, cylindrical, and blunt.

The original species' of this genus was O. aplylla, Eich., which 



was afterwards reduced to Anyrcecum. This plant and several 



others closely allied to it have so many remarkable characters in 



common not possessed by any others in the genus Mystacidium, 



that it Beems more satisfactory to restore the old genus Gussonia
