A very variable plant. Small states sometimes have the throat of the 
corolla either without scales or with very obscure ones. This character was 
used by De Candolle to constitute his subgenus Gymnomyosotis, but there is a 
gradual transition from flowers without scales to others in which they are as 
well developed as in other species of the genus, and looking at the fact that the 
filaments are at least longer than the anthers it seems best to place the species 
in the subgenus Hxarrhena, and in the neighbourhood of M. petiolata. 
Some specimens collected by Petrie at Inch-Clutha (Otago) and by Kirk at 
Winton (Southland) have precisely the habit of M. spathulata, and the calyx and 
fruit are the same. But the flowers are rather smaller, the throat of the corolla 
is furnished with evident scales, and the filaments are shorter than the anthers, 
so that the latter are entirely included in the corolla-tube, their tips not reach- 
ing the level of the scales. This form will probably prove to be a distinct 
species. 
15. M. petiolata, Hook. f. Fl. Nov. Zel. i. 202.—Perennial ; 
sparsely clothed with short white scabrid hairs ; rootstock long, 
stout or slender; stems usually numerous, decumbent or prostrate 
at the base, then ascending, slender, sparingly leafy, 4-14 in. long. 
Radical and lower cauline leaves on long slender petioles 4-3 in. 
long; blade 2-2in., broadly elliptic-oblong or elliptic-obovate, 
apiculate or rounded or retuse at the tip, thin and membranous, both 
surfaces slightly scabrid; upper cauline sessile, broadly obovate- 
spathulate. Racemes long, slender, many-flowered, simple or 
forked. Flowers 4-+in. diam., white or white with a yellow eye; 
pedicels rather long, slender, spreading. Calyx clothed with 
straight appressed hairs, d-lobed almost to the base; lobes linear, 
acute. Corolla broad, campanulate; tube very short, with 5 scales 
at the throat; limb several times longer than the tube, deeply 
d-lobed ; lobes oblong, spreading. Stamens with long and slender 
filaments; anthers far exserted beyond the tube, almost reaching 
the top of the corolla-lobes. Nutlets broadly ovoid, polished and 
shining, dark red-brown or black.—-Exarrhena petiolata, Hook. f.
