304 SXXIX. COMPOSITAE. [Raoulia. 



7. R. subulataj Hook, f., Handbk. 149. Densely tufted, rigid, glabrous 

 in all its parts. Stems ^in.-lin. high. Leaves densely imbricate, |-in. long 

 or more, rigid, subulate, acuminate, 1-nerved. Heads Jin.-^in. in diameter; 

 involucral bracts in 2-3 series, scarious, linear-lanceolate, acuminate. Recep- 

 tacle convex, hispid. Florets 20-35, those of the disk predominating ; mouth 

 almost campanulate, 5-toothed. Achene puberulous or silky. Pappus-hairs 

 slightly thickened at the tips. 



SOUTH Island : Nelson : mountains above Wairau Gorge, Sinclair, Gheeseman ! Alps of 

 Canterbury, J. B. Armstrong. Otago : Lake district, Hector and Buchanan! Old Man Range, 

 Hector Mountains, Mount Pisa, Mount Tyndall, &c., Petrie ! 4,000ft. to 6,000ft. Jan. 



A very distinct species, not easily mistaken for any other. I have not seen Canterbury 

 specimens. 



8. R. eximia, Hook. /., Handbk. 149. Forming small or large densely- 

 compacted grey tomentose hummocky masses on the mountains, from a few 

 inches to several feet long, 1ft. high or more. Rootstock woody. Branches 

 with the leaves fully Jin. in diameter. Leaves in many series, densely im- 

 bricated all round the stem, j-V'^-^s™- lo'^gj membranous, narrow obovate- 

 oblong, bearing near the tips on both surfaces a dense tuft of long silky hairs 

 meeting beyond the tip, which is completely hidden ; lower three-quarters 

 glabrous above, cottony or woolly beneath. Heads very numerous, sunk 

 amongst the apical leaves ; involucral bracts in 2 or 3 series ; outer linear- 

 spathulate, with a long scarious claw and a tuft of hairs on both surfaces at 

 the very tip ; inner linear-oblong, tips not radiating. Receptacle very small, 

 narrow, convex. Female florets 6, hermaphrodite 4, tubular; teeth extremely 

 minute. Achene with long erect silky hairs. Pappus-hairs very few, thickened 

 above. 



SOUTH Island : Canterbury : Mount Torlesse, Haast ! Enys and Kirh. Mount Dobson, 

 Saast ! Otago : Buchanan I Mount Ida Range, Petrie ! 4,000ft. to 5,000ft. Vegetable sheep. Jan. 



Closely related to B. mammillaris, but distinguished by longer branches, more woolly leaves, 

 and by the absence of white radiating involucral bracts, although in old specimens the scarious 

 bracts sometimes show a tendency to curve outwards. The leaves are excessively woolly, giving a 

 most deceptive appearance of softness to the mass, which in dry weather is as hard and unyielding 

 as the rook on which it grows. The Mount Torlesse plant is rightly referred here, and I have no 

 certain knowledge of any other stations for B. eximia than those already mentioned. It is desirable 

 that some Canterbury botanist should visit the Ribbonwood Range, Mount Dobson, and Mount 

 Arrowsmith, to determine the species reported from those localities. 



Var. lata. Leaves less densely imbricate than in the typical form, jijiu. long, broadly oblong, 

 concave above, rounded at the tip. Hairs long but less uneven than in the type. Heads not seen. 

 This is only known to me from a specimen collected by Enys and forwarded by the Director of the 

 Royal Gardens, Kew, without mention of locality, as B. eximia, with the following note by Mr. N. E. 

 Brown : " This may be a variety of B. eximia, but I doubt it ; the heads seem smaller, the hairs 

 shorter, and the phyllotaxis difierent." In the absence of flower-heads I am unable to separate it 

 from B. eximia. 



9. R. Hectori, Hook. /., Handbk. 149. Stems prostrate, lin.-3in. long, 

 densely tufted, much branched. Branches erect or ascending, fin.-2iu. high. 

 Leaves densely imbricate, broadly ovate, obtuse, coriaceous, silvery on both 

 surfaces except the membranous base, longitudinally grooved at the back. 

 Heads sunk amongst the apical leaves, J^in.-Jin. in diameter ; involucral 

 bracts few, in 2 series, the outer cottony, the inner linear-oblong, scarious,
