Abrotanella.] XXXIX. COMPOSITAE. 331 



AUCKLAND Islands : 1,000ft. to 2,000£t. CAMPBELL Islands : 500ft. to 800£t. Jan., Feb. 



The largest species. The cellular structure of the veins of the involuoral bracts and of the 

 ribs of the achenes becomes obscured after maturation. 



2. A. rosulata, Hook, f., Handbk. 139. Tufted. Stems prostrate or 

 suberect, ^in.— IJin. high. Leaves Jin.— ^in. long, narrow-ovate or lanceolate, 

 inabricating, acute or subacute, patent or recurved, concave above, rigid, very 

 coriaceous, 5-nerved beneath. Heads 3—6, terminal, partly hidden by the apical 

 leaves ; involucral bracts 8—10, linear-oblong, 3-nerved. Female florets tubular, 

 swollen at the base, 4-toothed ; achene tetragonous, 4-ribbed, narrowed below, 

 each rib produced upwards into a short horn. Male florets 4-angled ; teeth 

 erect. — Ceratella rosulata, Hook, f., Fl. Antarc. i. 35, t. 18. 



CAMPBELL Island : rare and local ; 800ft. to 1,000ft. Jan., Feb. 



3. A. linearis, Bergg. in Minneskr. Fisiog. Sdlisk, Lund. viii. (1877) 14, 

 t. 3, /. 28—38. Tufted, scapigerous, rarely exceeding 2in. in height. Leaves 

 equalling or slightly exceeding the scape, Jin.— 2in. long, linear, obtuse or 

 apiculate, with sheathing slightly hairy bases. Scapes Jin.— IJin. high, with 1 

 or several linear obtuse bracts. Head solitary ; involucral bracts subacute, 

 obscurely 3-nerved. Female florets about 4, deeply 4-toothed; achenes clavate, 

 rounded above, 4'-ribbed. Male : corolla longer ; achene tetragonous, abruptly 

 truncate above. — T. Kirk in Trans. N.Z.I, xxiv. (1891) 420. 



SOUTH Island : mountains of Nelson, Westland, Canterbury, and Otago, 2,000ft. to 3,500ft. 

 STEWART Island, sea-level to 2,000ft. Dec, Jan. 



Diminutive specimens are sometimes less than fin. high ; ou the other hand, the leaves 

 occasionally exceed 2in. in length, and the rootstook is sometimes largely developed, the decaying 

 bases of the old leaves being more or less persistent. 



4. A. caespitosa, Petrie MS. ex T. Kirk in Trans. N.Z.L xxiv. (1891) 

 420. Tufted. Stems fin.— Jin. high. Radical leaves recurved, fin. long, 

 linear obtuse, concave above, with a scarious margm when young, coriaceous. 

 Scapes naked or with 1 or 2 short bracts. Head solitary ; involucral bracts 

 7 or 8, broadly rounded at the apex, 3-nerved ; margins broad, scarious. Florets 

 6—12. Female achenes clavate, rounded above, obscurely 4-ribbed. Disk- 

 achenes tetragonous, abruptly truncate. 



SOUTH Island : mountains above the Broken River basin ; Craigieburn Mountains, Canter- 

 bury ; Clarke's Diggings, Mount Ida and Mount Kyeburn, Otago; Petrie t 3,500ft. to 5,000ft. Nov. 

 to Jan. 



A curious little plant, combining the leaves of A. spathulata with the solitary head of A. 

 linearis, but smaller in all its parts than either. In the original description only immature achenes 

 were available ; better specimens are still wanted. Perhaps only an aberrant form of A, linearis, 

 although it looks very different. 



5. A. inconspicua, Hook. /., Handbk. 140. Stems prostrate, Jin.-2in. 

 high. Leaves Jin.— Jin. long, densely crowded, spreading or ascending, subulate 

 or linear-oblong, concave at the base, subacute, rigid and rather flat when dry. 

 Head solitary, nearly hidden amongst the upper leaves ; involucral bracts linear- 

 oblong, 3-nerved, obtuse. Florets 15—20 : female slightly swollen at the base ;
