Auckland Islands : Moist rocky places on the hills ; Hooker, Homb. & Jacq., 

 Kirk, Tennant ! Macquarie Island : In swamps ; A. Hamilton. (New Zealand, 

 from the North Cape southwards.) 



The specimens gathered by the expedition entirely agree with the common New 

 Zealand state. 



Umbelliferae, 

 Azorella Selago, Hook. f. 



Azorella Selago, Hook, l, Fl. Antarct., ii, 284, t. 99 (1847). 



Macquarie Island : Sides of the hills, forming prominent globular masses often 

 4 ft. in diameter ; Fraser, Professor Scott ! A. Hamilton ! (Fuegia ; Kerguelen 

 Island ; Crozets ; Marion Island ; Heard Island.) 



Forms large convex masses several feet in diameter, composed of the closely 

 packed stems and branches of the plant ; the young shoots, with their leaves, form- 

 ing a bright-green smooth and even crust or surface, so densely compacted as to bear 

 the weight of a man. Under this living surface, as Sir Joseph Hooker remarks, 

 lies " a vast mound of debris, the remains of former years' growth, through which 

 the roots descend to the ground.." According to Dr. Scott, it is comparatively 

 rare in Macquarie Island ; but in Kerguelen Island it is the most abundant plant, 

 often forming sheets or hummocks investing the soil for acres in extent with an 

 elastic green coating. Its apparent absence in the Auckland and Campbell Islands 

 is a very curious fact, in no way easy to account for. 



Azorella reniformis, Hook. f. 



Pozoa reniformis. Hook, f., Fl. Antarct., i, 15, t. 11 (1844). Azorella reni- 

 formis, Benth. & Hook. f. in Gen. Plant., i, 875 (1865). 



Auckland and Campbell Islands : Rocky places on the hills ; Hooker, Kirk ! 

 Cockayne, Aston ! Tennant ! (Endemic.) 



The New Zealand A. Haastii is so close to this that it is highly doubtful if it 

 can be maintained as a distinct species, for the characters of the ciliate stipules and 

 long pedicels to the fruit, relied upon by Hooker, break down when large suites of 

 specimens are under examination. A. Haastii, however, attains a much larger size 

 than A. reniformis. 



Apium prostratum, Lab. 



Ajoium prostratum, Lab., Relat., i, 141 (1804). A. australe, Thouars, Fl. 

 Tristan d'Acugn., 43 (1811) ; Hook, f., Fl. Nov. Zel., i, 86 (1853). 



Antipodes Island : Maritime rocks, abundant ; Kirk, Cockayne. (Shores of 

 New Zealand, from the Kermadec Islands to Stewart Island ; Australia, from Queens-
