This terrestrial Liparis has some affinity with L. Bowkeri, 

 Harvey, a Cape plant. The lower part of the stem, about 2 

 inches, is covered with white membranous leaf- sheaths ; above 

 these are the leaves, generally two in number, ovate, with rather 

 short petioles ; they are 5-ribbed, and 2 inches in length by 1 in 

 diameter. The flower-spike is rather lax, and bears from 3 to 

 12 light-green flowers, rather large in size for a Liparis ; their 

 pedicels about \ an inch. The linear dorsal sepal is 5 lines in 

 length, twice the length of the column. The lateral sepals are 

 somewhat similar in shape to those of L. Bowkeri, rather broad 

 and falcate, 4g lines in length. In one specimen they were con- 

 nate for a portion of their length, but separate at each end. The 

 lip was broadly cordate, 5 lines long, base narrowed ; a rather
