scales of the involucre in var.y. are more numerous and imbricated ; and in
the plant of Drummond from St. Louis (A. Arnottii, JSees. ined.) they are
broader, more obtuse, and remarkably appressed : other specimens of this
variety (A. patentissimus, Lindl. in herb. Torr., which however have the
leaves very scabrous on both sides) pass insensibly into the ordinary state of
the plant.—The lower leaves, except in var. 6., rarely exceed one or two
inches in length, and are mostly obtuse, but mucronate. In that, plant, however,
they vary from 3 to 6 inches in length, usually tapering to each end,
but are dilated and auriculate at the base ; they occasionally present a fewje-
mote serratures. We were strongly disposed to consider it a distinct species
• but are now convinced by the examination of numerous intermediate
forms, that it is a state which the plant assumes in shady moist places.
