The nearest ally of S. Haastii is undoubtedly the Auckland Islands S. reniforme, 
which only differs in its smaller size, entire stipules, few-flowered umbels, and fruit 
always longer than its pedicel. But reduced states of S. Haastii come very near to 
A. reniforme, and in fact have been mistaken for it both by myself and the late Mr. 
Kirk (see ‘‘ Students’ Flora,” p. 192). 
Domin’s variety cyanopetalum will probably stand as a variety if based on the 
characters quoted above. He describes it as possessing “blue petals.” This I 
believe to be incorrect so far as the fresh state is concerned, but I have frequently 
noticed the petals to take on a bluish tinge when drying. 
5. ERYNGIUM Linn. 
Perennial herbs. . Leaves usually rigid and coriaceous, spinous-toothed, 
entire lobed or dissected. Flowers sessile in dense heads, with a bracteole 
under each flower, and a whorl of rigid often spinous-pointed bracts at the 
base of the head. Calyx-tube clothed with hyaline scales; teeth rigid, 
acute. Petals narrow, erect, deeply notched, with a long inflected point. 
Fruit ovoid or obovoid, scarcely compressed, covered with hyaline scales 
or tubercles; carpels semi-terete, primary ridges obscure, secondary 
wanting ; vittae inconspicuous or absent. 
A large genus of over 220 species, spread through most temperate and subtropical 
regions, but most plentiful in South America and western Asia. The single species 
found in New Zealand extends to Australia as well.

rigid spinous herb 2-9in. high, with tufted radical leaves and prostrate 
stems much resembling stolons but not rooting. Radical leaves crowded, 
rosulate, 3-6 in. long, lanceolate or oblanceolate or spathulate-lanceolate, 
deeply toothed or almost pinnatifid, the teeth spinescent, narrowed into 
a broad flat petiole. Cauline leaves much smaller, opposite, cuneate or 
linear-cuneate, with fewer spinous teeth. Peduncles radical or from the 
nodes, 3-2 in. long, bearing a single globose or broadly ovoid head 4-3 in.

far exceeding the flowers. Calyx-tube densely scaly.—Hook. f. Fl. Nov.
