306 XXXIX. COMPOSITAE. [Raoulia. 



the base. Heads sessile, deeply sunk amongst the apical leaves, x'^in. in 

 diameter ; involucral bracts numerous, glabrous, narrow-linear, obtuse, the 

 inner linear-spathulate with short radiating tips. Disk-florets broadly tubular, 

 5-toothed. Florets 10-14. Corolla dark-crimson. Achene pilose. Pappus- 

 hairs thickened upwards, barbellate.

I have not seen flowering specimens of this curious plant, and have therefore copied portions 

 of Mr. Buchanan's description. 



13. R. mammillaris, Hook, f., Handbk. Forming large densely-com- 

 pacted rounded or amorphous knobby grey masses or patches, from a few 

 inches to several feet in length and 1ft.— 3ft. high. Branches very short, 

 thick, with the leaves fully Jin. in diameter. Leaves imbricated all round the 

 stem in many series, densely compacted, spreading, j'^in.— jJ^in. long, narrow 

 obovate-spathulate or cuneate, rounded at the apex, membranous, cottony or 

 woolly beneath, both surfaces bearing a dense tuft of short hairs just below the 

 tip, produced beyond the margins, which are completely hidden. Heads deeply 

 sunk amongst the apical leaves, ^in. long. Florets about 10. Inner involucral 

 bracts linear-oblong, scarious, with very short white acute radiating tips. 

 Receptacle convex, naked. Achenes with a thickened areole at the base, com- 

 pressed, broad, copiously clothed with long erect or spreading white silky hairs. 

 Pappus -hairs few, thickened at the tips. 



SOUTH Island : Nelson : Mount Starveall, Bryant ! Canterbury : the plant found on the 

 Ribbonwood Range, Mount Arrowsmith, and Mount Dobson by Sinclair and Haast probably belongs 

 to this, but I have not seen specimens. 5,000ft. to 6,000ft. Vegetahle sheep. 



Perhaps best distinguished from B,. eximia by the "knobby" habit, short branches, small 

 leaves, and short radiating Involucral bracts. Hooker describes the hairs of this species as not 

 exceeding the tip of the leaf, but all the specimens seen by me have much longer hairs ; those so 

 named at Kew agree in this particular. Much confusion exists with regard to the habitats of this 

 species and B. eximia. Haast's Mount Torlesse habitat certainly belongs to the latter, although it 

 is the only station given in the Handbook for R. mammillaris ; and it may well be that Sinclair and 

 Haast's stations cited above are really identical with Mount Starveall ; at any rate, until observed 

 by Mr. Bryant on that mountain it had not been seen by any New Zealand botanist since its original 

 discovery. A specimen named B. mammillaris, kindly given me by the Director of the Royal 

 Gardens, is certainly B. eximia. I have not seen florets in a good condition. 



14. R. Goyeni, T. Kirk in Trans. N.Z.I, xvi. (1883) 373. Forming 

 hard dense compact rounded or amorphous much-branched greenish masses 

 from a few inches to 2ft.-3ft. long, but rarely exceeding 6in. high. Rootstock 

 stout, woody. Branches short, with the leaves fully Jin. in diameter. Leaves 

 densely imbricated in many series, extremely membranous, sessile by a broad 

 base, narrow linear-oblong, iin.-^in. long, rounded, truncate at the apex with a 

 narrow margin, slightly contracted at the middle; the apical portion of the 

 upper surface clothed with a dense brush of short white uneven hairs slightly 

 exceeding the margin, glabrous at the base. Heads deeply sunk amongst the 

 apical leaves, short ; involucral bracts in 1 or 2 series, the outer narrow linear- 

 spathulate, with a scarious margin and tufts of hairs at the tip, the inner 

 narrow-linear, scarious, mostly obtuse, a few with short scarcely radiating tips.
