The annual root very long, white. Stem 2-4 inches high; branches 2-5 inches 
long, lower ones opposite, dichotomously divided. Leaves 3-6 lines long, 1 line 
wide ; floral ones or bracteze rather longer. Calyx-tube in flower 1 line, lobes 2-4, 
sometimes 6-7 lines long. Corolla blue and white (Thb.), tubular-infundibuliform, 
4-6 lines long. Stigma §-lobed. Capsule coriaceous, 2-2} lines long, crowned by 
the rigid, elongated lobes, wholly inferior ; the valves are depressed, and not elevated 
and superior, as in M. glomeratum. In some specimens, however, and chiefly in 
the small ones, which I think to be MW. sparsiflorum, A. DC., there are rudimentary 
or perfectly developed superior valves, about 3 line long. 
XII WAHLENBERGIA, Schrad. 
Calyx 5-3-fid. Corolla 5-3-lobed at the apex, rarely divided to the 
middle, infundibuliform, subeampanulate, or tubulose. Stamens 5-3, 
free ; filaments broad at the base. Style inclosed, pilose, particularly 
in the upper part. Stigmas 5-2, often linear, short. Capsule 5-3-2- 
celled, each opening by so many valves at the apex; valves with a 
dissepiment in the middle ; cells (when 5) opposite to the calycine 
lobes, Seeds numerous, minute. Schrad. in Catal. Hort. Goetting.

often elongated, filiform, terminal or opposite to a leaf. Flowers at first drooping ; 
the capsule erect. Name in honour of George Wahlenberg, professor of botany in
