700 PHANEROGAM I A. 



Styles elongated. Only one flower of each umbel usually fructifies. 

 Fruit not exceeding the leaves at the summit of the shoot, turgid, 

 globular, but dorsally somewhat compressed, 2 lines long, utricular (as 

 in A. Gllllesii), the entirely loose and membranaceous epicarp smooth 

 and free from ribs or markings : on detaching the membrane, how- 

 ever, the five filiform ribs are seen on the body of the compressed meri- 

 carp, three on the back and one on each margin. Vittse none. 



This can hardly be any state of Azorella ccespitosa of Cavanilles, 

 which is described and figured as having, at least in the fruiting state, 

 a conspicuously exserted peduncle and slender pedicels, as well as 

 squarrose-spreading leaves. It is much more like the Antarctic plant, 

 however, as described by Dr. Hooker under this name ; but that is 

 said to have the calyx-tube hairy; and Dr. Hooker would scarcely fail 

 to mention the utricular character, which is manifest even in the im- 

 mature fruit. Moreover the leaves of our plant are appressed, rather 

 than spreading.
