36 FLORA ANTARCTICA. [Auckland and 



C. longifolia (1.). This is the original species, whereon the genus was founded by Cassini ; the specimens 

 having been brought home by Gaudichaud from the voyage of Admiral Freycinet, and described in ' Diet. Sc. 

 Nat.' vol. xxxvii. p. 259. DeCandolle considers Cunningham's Blue Mountain species (Arctotis gnaphalodes, 

 Cunn. MS. in Herb. Hook.) as identical with this. Our specimens differ from Gaudichaud's figure only by 

 having the leaves much narrower, with their margins revolute and the scapes far less leafy upwards. The 

 achsenia are constantly glabrous, the pappus pale reddish, and the papillose part of the arms of the style is as long 

 as the linear and glabrous portion. Of the C. spathulata (2.), A. C. MSS., we have no specimens ; in its gla- 

 brous foliage it differs from all but C. vernicosa. A third species is founded on a Tasmanian plant not rare on the 

 summit of Mount Wellington, where it forms large matted patches. The first specimens I had seen were ga- 

 thered there by Mr. Frazer, and more latterly by myself and Mr. Gunn, who detected it in other mountainous 

 parts of the colony. I have called it C. asteliafolia (3.), from the great similarity it bears in foliage, general 

 aspect and habitat to Aste/ia alpina, Br. The leaves are extremely variable in breadth and in the degree of re- 

 curving in their margins ; they are often very like those of C. longifolia, but never exceed a span in length. The 

 scapes too are longer, less leafy, and the flowers larger than in that species ; the hairy achsenia also afford a 

 constant character. The flowers of the ray are pink, the pappus yellow. The above three species are Austra- 

 lian. Those found in New Zealand are C. gracilenta (4.), a plant so very near, even in the variable form 

 of its leaves, to C. longifolia, that it was not till I had examined the styles that I could detect any differ- 

 ence ; the conical papillose portion of these being much produced, gradually acuminated, and three times the 

 length of the lower part of the arms, with the papilla; almost filiform. From C. astelitefolia it differs in having 

 a glabrous achsenium, which is much longer than in any of the former species. Nearly allied to this is the 

 C. graminifolia (5.), mainly distinguished from the former by its foliage. Decidedly the finest species are 

 the three following, two of them originally discovered and described by Forster ; the first is C. spectabilis (6.), 

 of which I possess a specimen from Mr, Bidwill. Though hardly exceeding a span in length, including the 

 scape, the base of the stem, while covered with the sheathing leaves, is fully an inch in diameter, and densely 

 clothed with long, beautifully silky wool. The leaves are broad and remarkably coriaceous, their upper surface, 

 in the dried state, minutely striated with anastomosing lines, and the under densely clothed with buff-coloured 

 appressed tomentura. The scape is stout, loosely covered with shaggy white wool, and producing a large, solitary, 

 apparently white flower, an inch and a half broad. The achaenia are elongated, all of them glabrous ; the tubes 

 of the corolla, especially of the ray, have long, straight, pellucid, scattered, distantly jointed, and very slender 

 hairs. Pappus yellow, rigid ; the outer setae, as in the other species of the genus, short, the rest gradually length- 

 ening. Ligules of the flowers of the ray linear, abruptly truncated, with three large teeth and four nerves. Anthers 

 shortly biaristate at the base ; styles with the arms rather elongated, the conical papillose portion of those of 

 the disc short and rather obtuse. Forster's first species, C. holosericea (Aster, Forst.), has been found, I be- 

 lieve, by that botanist alone : his specimens exist in the British Museum, accompanied by his fine drawing of 



sime sericeo-lanatis supra glabris subtus tomento fulvo appresso densissime obtectis, achaeniis glaberrimis, tubo 

 corolla? piloso, antheris breviter biaristatis.
