CuEESBMAN. — A'fw Species of L'ldittK. 177 



■and terete above ; blade 4-7 in. long by 3-6 in. across, cordate to orbi- 

 cular-cordate, deeply lobed at the base, acute at the tip, thin and mem- 

 branous, veins reticulate, margins sinuate and finely spinuloso-serrate. 

 Cauline leaves smaller, on shorter petioles, with large leafy auricles and 

 smaller narrower blades, gradually passing into lanceolate or linear entire 

 bracts. Corymbs large and broad, much branched ; branches slender. 

 Heads very numerous, |-1^ in. diameter, bright yellow ; involucral bracts 

 in a single series, linear or oblong-linear, acute, glabrous or finely pubescent. 

 Ray-florets 10-15 ; ligule narrow, spreading ; disc-florets 25-35. Ripe 

 achenes not seen. Pappus soft, copious, white. 



One of the most distinct species added to the New Zealand flora of late 

 years. Although allied to S. latifolius, it differs widely in habit, in the 

 large cordate leaves, which are never lobulate or pinnatifid, but have their 

 margins finely spinulose-serrate, in the long terete petioles, and in the 

 larger flower-heads. I have much pleasure in dedicating it to its zealous 

 discoverer, who has done excellent botanical work in the interior of the 

 North Island of late years. 



Mr. Turner remarks, " As far as at present noticed, the plant is restricted 

 to the mouth of the Mangaio Gorge and the steep papa clif?s of the Wanganui 

 River above and near the junction, but I have fomid only one place at 

 which it can be conveniently reached. It is associated with Ourisia macro- 

 pliylla, Senecio latifolius, Elatostemma rugosum, and Lomaria capensis, and 

 grows only where the clifTs are wet and shaded. From a little distance the 

 large bright-green leaves give the plant somewhat the appearance of the 

 arum lily."

 Tongonge and the coast ; R. H. Matthews ! 



Stem slender, wiry, flexuose, 4-6 in. high. Leaf solitary, sheathing 

 the stem at the base, the sheath finely and closely puberulous ; lamina 

 1^2J in. long, much expanded at the base, and then suddenly narrowed 

 into a linear blade, which is usually spirally twisted so as to coil round the 

 stem ; margins involute. Bracts 2, the lower one below the middle of the 

 stem, the upper almost close to the flower, both broad and sheathing. 

 Flower solitary, large for the size of the plant, J-| in. diameter. Perianth - 

 segments alike, lanceolate or oblong-lanceolate, acute or shortly acuminate, 

 dark purplish-blue with darker longitudinal veins. Column much shorter 

 than the perianth-segments, not produced at the back behind the anther, 

 but furnished with two large lateral lobes which equal the anther in height, 

 and which are oblong or oblong-falcate, obtuse, somewhat flattened but 

 thick and fleshy, not lobed nor furnished with cilia. Occasionally there 

 are evidences of a slight crest connecting the lateral lobes at the base. , 

 Anther very large, oblong, obtuse. Base of the column purplish ; lateral 

 lobes and anther bright vellow.
