The vascular flora of macquarie island.—cheeseman. 19 
H. Hamilton’s specimens, which are all I have seen from Macquarie Island, are 
rather smaller than those which I possess from the Auckland and Campbell Islands. 
Hooker remarks in the “ Flora Antarctica” that “ the peduncles generally bear two 
pedicels,” but I find that in all the specimens I have seen from the Southern Islands 
the majority of the peduncles are 1-flowered. 
S. decipiens is confined to the Subantarctic Islands of New Zealand. It is 
closely allied to S. media, but is smaller, with smaller leaves and a less developed 
inflorescence; and it does not possess the pubescent line along the branches so evident 
in that plant.

Macquarie Island :—Abundantly naturalized. A. Hamilton (1894); H. Hamilton, 
(1912-1913). 
A. Hamilton remarks that this is one of the plants that have succeeded in 
naturalizing themselves near the factories, having probably been introduced in the 
straw packing of the machinery. H. Hamilton has also informed me that he found it 
plentiful near the residences of the sealers. 
Stellaria media was originally confined to the north temperate zone, extending 
northwards to the arctic circle, but during the last hundred years it has followed the 
footsteps of man all over the world, especially in cool damp climates. Although thin 
and delicate in habit and appearance, it is really one of the hardiest plants known; 
and as it produces seed from the beginning of spring to the close of autumn, its 
regeneration each year is assured. It is now spread all through the subantarctic 
regions, from Fuegia and the Falkland Islands to Kerguelen Island, South Georgia, 
Marion Island, St. Paul and Amsterdam Islands. In the islands to the south of New 
Zealand it is now found on every island of the group.

Macquarie Island :—A. Hamilton (1894); H. Hamilton (1912-1913). 
This species, like Stellaria media, has of late years spread from its original home 
in the north temperate zone to most parts of the world. It was first recorded from 
Macquarie Island by A. Hamilton, his specimens being identified by Kirk, who reported 
that they represented an unusually luxuriant state, with almost fleshy leaves. The 
same remarks can be applied to H. Hamilton’s specimens, labelled “ The Nuggets, near
