Celmisia.] XXXIX. COMPOSITAE. 279 



7. CELMISIA, Cass. 



Involucre broadly hemispherical ; involucral bracts in few or many series? 

 imbricatingj pubescent cottony silky or glandular ; tips scarious^ often re- 

 curved. Receptacle plane or convex, often deeply pitted. Hay-florets female, 

 1-seriate, spreading, flat or revolute, often very long, invariably white. Disk- 

 florets hermaphrodite, tubular, 5-toothed. Anthers usually sagittate at the 

 base, with short acute or rarely obtuse tails. Style-arms flattened, tipped with 

 long or short cones or appendages, papillose on the back. Acheues linear, 

 slightly compressed or angled, with 2 or 3 prominent ribs on each side. Pappus 

 unequal, the hairs often shortly bifid. Tufted herbs, with fleshy root-fibres or . 

 short branched rhizomes, rarely suffruticose and erect. Leaves all radical or 

 rarely cauline and densely imbricating, usually narrowed into sheathing bases, 

 clothed beneath with appressed or lax tomentum. Heads large, solitary, ter- 

 minating bracteate scapes, or rarely sessile or on axillary peduncles. 



A beautiful genus, comprising the various " mountain daisies" of the settlers. Many of the 

 species are extremely variable, and pass into each other by easy gradations. It differs from Olearia 

 only in habit, such species as G. Walkeri and C. ramulosa having an equal claim to be placed in 

 either genua. From Pleurophyllum it differs only in the solitary heads and white rays. The habit 

 is exactly that of Aster aLpinus, L., which, except for the anthers, might very well be referred to 

 Celviisia. Under cultivation some of the stronger-growing species frequenbly develop branched 

 scapes. All the species are endemic in New Zealand except G. longifolia, which extends to Aus- 

 tralia, and the doubtful C. Lechleri, Sch. Bip., which is restricted to Peru.
