base arching partly over stem, postical base slightly decurrent, apex 
bidentulate, rarely obtuse or acute, teeth small, acute or obtuse, | to 3 
cells long: cells of leaf polygonal, thin-walled, cavities angular, tri-

twice the width of stem, subtransversely inserted, decurrent, broadly 
reniform, deeply bifid (about two-thirds), lobes entire or unequally 
cleft, divisions acute or obtuse, sinus separating lobes obtuse or 
lunate ; cells of underleaves similar to those of leaf but somewhat 
smaller : 2 inflorescence usually borne singly, sometimes two@, a ¢ 
and a 9, or a @ and a vegetative branch borne from the axil of 
the same underleaf; bracts in two or three pairs, small, broadly 
ovate, usually bifid ; bracteoles similar to bracts : andreecium a short 
branch, usually borne singly but sometimes in pairs from the axils 
of the underleaves: ¢ bracts in 4 to 8 pairs, ovate, deeply bifid

This species is very common in damp, shady valleys, growing on 
the ground. It is about the same size as the widely distributed A. 
Trichomanis, of Europe and North America, but its leaves are nar- 
rower, more acute, and almost always bidentulate ; the leaf-cells also 
are much larger and with thinner cell-walls, and the underleaves are 
wider in proportion to their length.
