ASTER STILETTIFORMIS 165 
From 4. virgularius, which its smaller form resembles, it differs 
in its broader, rounder, greener bracts, in its truncate-based sessile 
axiles, and its far more salient teeth. It is usually a much larger 
plant, and its typical leaves are narrower. 
It resembles both these species in the prominence of its teeth, 
and A. virgularius in their form. It differs from both in its slit- 
toothed straighter-sided leaves, its bracts nearly without white or 
scarious margins, and its axiles nearly without petioles, with trun- 
cate base and long closely-slit straight sides, suggesting a stiletto. 
Habitat, scattered in loamy half-shade, often on steep banks,
