fertis, |-1" longis, sa.pt brevissimis et acervato-proliferis. Corallum 

 ramulorum caliculis labellatis, labetto elongato, vix complanato ; api- 

 cali, elongate cylindrico, 2 2'" longo et f '" lato. 



Vasiform, pedicellate ; frond very broad, 1 to 2 inches thick ; branches 

 reticulately coalescent ; below complanate, without branchlets ; 

 above branchlets crowded, to 1 inch long, often very short and 

 acervato-proliferous. Corallum having the calicles labellate; lip 

 long and scarcely at all flattened ; the apical calicle long cylindrical; 

 2 to 2 lines long and ^ of a line broad.

The vases are often four feet in breadth, and stand on a pedicel one 

 to two feet in height. In one specimen the upper part is placed ob- 

 liquely, arising from an oblique position in the pedicel while growing. 

 The coalescing branches of the frond are not so far flattened and 

 united as to lose their individuality ; the open intervals are numerous, 

 yet narrower than the branches. The squarrose appearance of the 

 branchlets of the corallum, especially of those about the middle portion 

 of the vase, resembling proliferous heaps of calicles, allies the species 

 to the preceding. The branchlets, toward the margin, are about an 

 inch long, and have long calicles ; those of the margin itself are much 

 clustered. 



In weathered specimens (fig. 3 a), the calicles, just below the apex, 

 are sometimes worn off, leaving the apical calicle apparently a third 

 to half an inch in length.
