appressed tomentum, loosely cottony towards the base. Heads large, 
1-2 in. diam., sunk among the terminal leaves; involucral bracts in about 
2 series; the outer few, short, scarious; inner linear, obtuse, spreading, 
with long white radiating tips; receptacle small, convex, hispid. Florets 
25-40, about + female, narrow, the rest hermaphrodite. Achene silky.

Var. fasciculata: Tararua Mountains, H. H. Travers ! 
This species and R. Youngii differ greatly in habit from the other species of 
Raoulia, but the structure of the florets is that of the section Psychrophyton, in which 
they must be placed. With regard to var. fasciculata, I have shown in a note printed 
in Trans. N.Z. Inst. xliv (1912) (Proceedings), p. 25, that the structure of the florets is 
also that of Psychrophyton, and that the plant only differs from R. grandvflora in 
having 3 flower-heads to a stem. 
12. R. Heetori Hook. f. Handb. N.Z. Fl. (1864) 149.—Often forming 
broad dense patches. Stems prostrate, much branched, 1-3 in. long ; 
branches 1-2in. high, close-set, erect or ascending. Leaves closely 
imbricated, erecto-patent, ;4,-in. long, broadly ovate, obtuse, upper 
4 thick and coriaceous and clothed with appressed silvery tomentum, 
lower 4 membranous, glabrous, back longitudinally grooved when dry. 
Heads small, 1,1 in. diam., sunk amongst the terminal leaves; involucral 
bracts in 2 series, linear-oblong, scarious, subacute, glabrous, not white at 
the tips. Florets 10-18; female 3-6. Achene glabrous or nearly so.

Usually found on steep rocky slopes, where it forms broad flattened patches, often 
covering considerable areas. It never shows any tendency to form the rounded cushion- 
shaped masses so characteristic of R. extmia, R. mammillaris, and Rk. Buchanani.
