( Plant four or five inches high. E.) Stem and leaves very hairy; root- 
leaves oblong wedge-shaped, sessile, entire, very large; stem-leaves oval, 
slightly toothed or scolloped, not three-lobed, diminishing upwards, so 
as to give the whole plant somewhat of a pyramidal form ; in opposite 
alternate pairs ; the upper tinged with purple. Floral-leaves longer than 
the flowers. Flowers from the bosom of the leaves, not more than three 
together, (in whorls, E.) Calyx very hairy, divided half-way down: 
segments awl-shaped, nearly equal. Woodw.

The pairs of the leaves and the whorls are rather distant, by no means 
crowded into a pyramidal form as in A. pyramidalis , nor are the radical 
leaves (as in that species) three or four times as large as those on the 
stem, and very hairy; but, on the contrary, the lower leaves are but 
little larger than the others, and all very nearly smooth, veiny, unequally 
toothed. The hractece sometimes quite entire, sometimes toothed; the 
uppermost only tinged with purple; whereas in A. pyramidalis, they are
