STEM erect,, compound, irregularly and often subunila- 

 terally branched; HYDROTHEC.E very slender, long, with 

 an entire aperture, of a thin and fragile material, borne 

 on short pedicels, ivith 3 or 4 rings, or loosely twisted and 

 with two whorls; GONOTHECJE unknown. 



Height (when finely grown) about 3 inches. 



As compared with L. dumosa this species is eminently 

 delicate and fragile. It grows in shrubby tufts, and, when 

 living, is of a light yellow or citron-colour. The calycles 

 are distinctly stalked ; they are much narrowed below, and 

 a little above the base curve outwards on one side, 

 and are slightly concave at the opposite point : this gives 

 them a somewhat crooked appearance. The calycles of 

 L. dumosa are much straighter and stouter ; they are also 

 of denser texture and sessile. The present species is made 

 of much more delicate material than its sturdy ally, and, 

 when dried, sorely disappoints the collector, the calycles 

 shrivelling up and the specimen losing its beauty. 



I have identified the L. fruticosa (Sars) and the L. gra- 

 cillima (Alder), though not without some doubt. They 

 differ chiefly in the character of the pedicel, which in the 

 former is distinctly ringed, and from one-third to half the 

 length of the calycle, while in the latter it is loosely twisted, 

 " making about two turns " and not more than one-fourth 

 the length of the calycle. The hydrothecre also are
