and gives out numerous receptaculiferous brandies in all direc- 

 tions. Frequently one or more branches of the Phyllamphora 

 form are found in tlie jilaces usually occupied by the recep- 

 taculiferous branches. 



The apical portions of the axial stems of Laxgsdoef's form 

 are generally rubbed off. As a rule, the scale-like leaves are 

 entirely wanting on the axial stems throughout the whole length. 

 For a few inches from the basal point the stems are naked, but 

 with subprominent scars of the fallen leaves. 



Of the receptaculiferous lateral branches. Smith ^^ gave a 

 full description and beautiful illustration. He seems to have 

 doubted the existence of the small bulb at the base of each 

 lateral branch as described by Turner. I also was not able to 

 verify any such character as Turner described and illustrated. 



The stems of the lateral receptaculiferous branches are more 

 slender than the axial member and are covered with scale-like 

 leaves spirally arranged with a divergence of |. These leaves 

 are approximate below and gradually separate toward the apex 

 of the stems. The lower leaves are very small, hardly exceeding 

 1.5 mm. in length and 0.5 mm. in the broadest part, sessile, 

 entire and tapering upward ; the uj'tper ones become gently 

 elongated often attaining 10 mm., equally sessile and tapering 

 with but one or two obtuse teeth on the lower margins. In the 

 apical portions of the stems, the leaves are replaced by berry- 

 like hollow receptacles, each borne on a short stalk. The upper- 

 most receptacle on each branch, as a rule, is the largest. 



The stems of the Phyllamphora form are as thick as the 

 axial stem of Langsdorf's form, and are similarly covered with 

 scale-like leaves in similar arrangement. The leaves are, however,
