stem at x40 magnification.2 
1. Upper stems not white, indumentum very sparse to dense, stem surface 
visible at x40 magnification.4 
2 Leaf and stem indumentum appressed, retrorse, hairs 0.05-0.2 mm long.3 
2. Leaf and stem indumentum woolly, hairs without fixed direction, 
0.4-1.2 mm long.23. A. salviifolia

long; style 12-13 mm long; leaves often narrow (3-6.6 times longer than 
wide).3. A. brevipilosa 
3. External calyx hairs very dense, appressed, 0.15-0.25 mm long; 
style 9.5-10.5 mm long; leaves often broader (2.8-3.5 times longer than 
wide).9. A. farinacea 
4 Erect glandular hairs (0.1-0.3 mm long) frequent to abundant on upper 
stems and inflorescence rachis.5 
4. Erect glandular hairs absent from upper stems and rachises, although 
sessile glands usually present.6 
5 Patent hispid hairs absent from upper stems; cymes twice dichasial at 
base; cauline leaves 120-150 mm long; bracteoles 6.4-11 mm long. . .4. A. bundeyensis 
5. Patent hispid hairs present (often frequent) on upper stems; cymes 
monochasial or once dichasial at base; cauline leaves 51-110 mm long; 
bracteoles 2.5-7.5 mm long.24. A. viscidula
