Caespites densi, 1.2-2 cm, 3-6.2 cm longi, infra fusci, supra atrovirides, 

 leviter dilapsi. 



Caulis ramosus, in sectione transversa rotundatus fere semper autem ro- 

 tundato-triangularis; externe cellulis epidermidis uni-bistratosis obtectus, in 

 media parte parenchymatos corticalis cum "funiculo centrali" (Centralstrang) 

 (Plate III, fig. 2). Mensuram cellularum caulis vide in tabella 1.
