[Head before the (Jtago Institute^ Dth Jnli/, 1SS9.] 



Celnusia broivnii. 



Plant 9in.-12in. high. Eootstock short. 



Leaves 9in. long, oblong, subacute. Greatest width 3|^in., 

 falling away, first rapidly, then gradually, towards the petiole. 

 Petiolar part l-|in.-2in. long, broadening to a sheath. 

 Sheath membranous at edges, slightly purple near base on 

 lower side. Petiole and sheath glabrous. Upper surface of 

 leaf glabrous, with here and there a few scattered brown 

 hairs on young leaves grown in winter. Lower side covered 

 with close, short, French-grey tomentum, neither appressed 

 nor woolly, but like velvet or peach-down, with the grain 

 pointing towards the apex of the leaf. Midrib broad, shining, 

 semi-transparent, pale-green, narrowing but still naked to 

 the tip. The naked veins for the major part of their length 

 like threads of light-green running through the tomentum. 

 Viewed from above : Leaf longitudinally divided into about 

 twelve corrugations, as in C. rerbascifolia and some other 

 species ; petiole, and the midrib for half its length, semi-trans- 

 parent and pale-green, as from below. Leaf obscurely toothed 

 or rough at edges, the roughness being commonly masked by 

 tomentum. Colour of leaf from above, olive-green ; from 

 below, between French-grey and green. Leaf not rigid, but 

 rather kid-like to the touch. 



Scape, length same as that of leaves, or 2in.-3in. longer. 

 •Covered, like leaves, with hairy tomentum, through which it 

 retains its pale-green colom-. Very much flattened, and not 

 rigid. Bracts few, and only neai- the head leafy, 2iu.-4in. 

 long, glabrous near sheathing-base, tomentose near tip. 



Head 2in. in diameter. Involucral scales numerous, gla- 

 brous towards the tip, Hnear-subulate. Inner scales slightly 

 tomentose. Rays 100, in two series, |-in. long, -^^^n. w^ide. 

 Achene pilose, covered with sliort bright hairs ^in. long. 

 Pappus longer. Corolla-tube pilose, or silky like achene. 



Locality. Mystery Pass, Disaster Burn, between Lake 

 Manapouri and Smith Sound ; altitude, 3,000ft.-3,500ft. 



A single specimen of this plant, one of the finest of the 

 genus, was brought down by Mr. Malcolm Ross, who was a 

 member of the second search-party which went oat in De- 

 cember, 1888, to endeavour to ascertain the fate of my 

 lamented friend Professor Main waring Brown, in vdiose 

 memory I have named the species. I have succeeded in grow-
