COMPOSITE 155 



slightly dentate ; then oblong-ovate, obtuse, cuneate at the base, 

 more or less irregularly dentate. 



Ultimate leaves oblong, petiolate, lyrate-pinnatifid, felted on 

 both surfaces with a dense white tomentum ; terminal segment 

 ovate or triangular-ovate, large, pinnatifid at the base and toothed 

 upwards ; lateral segments alternate or subopposite, spathulate- 

 oblong, narrowed to an obtuse point, entire. 



Mutisia ilicifolia, Hook. (fig. 483). 



Hypocotyl extremely short, hardly appearing above the ground, 

 almost square, downy. 



Cotyledons ovate, thick, 

 fleshy, acute, recurved, with 

 their points penetrating the 

 ground, glabrous, dark green, 

 indistinctly nerved, with short 

 petioles. 



Stem erect, herbaceous, 

 almost square, thickly covered 

 with down ; 1st internode 

 very short ; 2nd longer. 



First leaves simple, cau- 

 line, alternate, ovate with a FIG. 483. Mutisia ilicifolia. 



cordate base, toothed or spiny, Half nat - size - 



sessile, clasping the stem, glabrous, light green, with a distinctly 

 reticulate venation. The buds are covered with a thick white down. 



Mutisia copiapina, Auct. 



Hypocotyl erect, terete, 7'5-10 mm. long, hoary, greenish, or 

 stained with red. 



Cotyledons oblong or slightly ovate, large, from 3'5-4 cm. long, 

 ascending, otherwise as in last species. 



Stem short, erect, terete, glabrous, light green ; 1st internode 

 1-2 mm. long ; 2nd shorter. 



Leaves oblong, otherwise as in the last species. 



In an abnormal specimen one of the cotyledons was divided down 

 to the base, forming two linear leaves, giving the plant the appear- 

 ance of having three cotyledons. 



Ainslisea fragrans, Champ. 



Hypocotyl rather succulent, 5-10 mm. long, 1 mm. thick, terete, 

 glabrous, reddish. 



Cotyledons shortly stalked, 1-5 cm. long, 5-7 mm. wide, ovate-
