 Levuka, Fiji Islands; J. M. Brower (3917). 



Only one of the original types of this species is now in the collection. 

 It is a small clump, about 10 centimeters in diameter and Co centime- 

 ters in greatest height, the longest branch measuring about 5.5 centi- 

 meters in length and 1.2 centimeters in thickness at the base. The 

 collection of Mr. Brower, from Levuka, contains a much larger and finer 

 specimen, diflering from the former only in its measurements. The 

 greatest spread of the clump is nearly 24 centimeters, the greatest height 

 about 11 centimeters. The base is much thickened so that the longest 

 branch measures only about 6.5 centimeters. The branches are very 

 stout, the largest being about 1.8 centimeters thick at the base ; their 

 characters are the same as in the type. The cells are large, the apical 

 measuring 4.5 millimeters across, and the lateral about 2 millimeters 

 midway of the branches, where they are also most prominent, being 

 generally much less exsert toward the base.
