Famity CRASSULACE.. | [Genus TILLAA, Linn. 
Tillaa moschata, D.C. Prodr. iii, 382; Cheesem. Man. N.Z. Fl. 140. 
Tillza Sieberiana, Schultz, Mant. 111, 345; Cheesem. Man. N.Z. Fl. 143. 
Tillea is a cosmopolitan genus that has representatives in most parts of the world, 
but I do not know any country that contains so many species as New Zealand, no 
less than ten being credited to it in our floras. Of these, the most interesting is 
Tillea moschata, which has a widespread distribution as a maritime plant in high 
southern latitudes. It stretches along the western coasts of South America from 
Chile to Cape Horn; is abundant on the Falkland Islands; is found on Kerguelen 
Island and Marion Island; and in New Zealand extends from Cook Strait to the 
Auckland and Campbell Islands, Antipodes Island, and Macquarie Island. It is 
thus one of those species found on most of those widely separated islands which 
girdle the globe between latitudes 50° and 60° S., and its distribution can therefore 
be described as being more or less circumpolar in its character. 
As a species T. moschata can be separated from its New Zealand allies by its 
much greater size, its stems often exceeding 6in. in length, its larger oblong- 
spathulate leaves, and larger flowers. It is purely a coastal plant, and is never 
found far from the sea. It should be remarked that it was first observed in both 
Fuegia and New Zealand by Banks and Solander during Cook’s first voyage. 
Tillea Sieberiana is a very different species from the foregoing. It is smaller 
in all its parts, much more erect in its mode of growth, and usually more copiously 
branched. The flowers are aggregated in clusters mixed with minute leaves, and 
there are no scales at the base of the carpels. Like the previous species, it was first 
gathered by Banks and Solander, and is abundant through the North and South 
Islands, from the Three Kings Islands and the North Cape southwards to the south 
of Otago. Although common on coastal rocks, it is by no means confined to the 
vicinity of the sea, but extends into many inland districts, ascending to at least 
2,000 ft. above sea-level. It is also widely distributed in Australia, ranging from 
Queensland to Victoria, Tasmania, South Australia, and West Australia, and has 
been recorded from several localities in the interior.
