Gen. Char. Calyx (fig. 1.) of 4, converging, strap-shaped, 
concave, upright, deciduous sepals ; the 2 opposite ones protube- 
rent at the base. Corolla (see fig. 2.) cruciform, of 4 inversely 
egff-shaped, spreading, entire, or broadly notched petals ; with up- 
right claws, the length of the calyx (see fig. 3). Filaments (fig. 4.) 
6, awl-shaped, simple, distinct ; the 2 outermost much the shortest, 
with a nectariferous gland at their base. Anthers oblong-arrow- 
shaped, nearly upright, of 2 strap-shaped lobes. Germen (see 
fig. 4.) oblong, rather compressed, shorter than the stamens. Style 
short and thick, frequently wanting. Stigma connivent, thickened 
or connate at the back. Pod (fig. 6.) strap-shaped, compressed, or 
nearly cylindrical, convex or keeled at one or both sides ; valves 
straight ; partition membranous. Seeds (fig. 7.) ranged alternately 
in a single row, orbicular, compressed, generally bordered. Coty- 
ledons flat, accumbent (o=), see figs. 8 & 9. 
The compressed or nearly cylindrical pod ; the converging stig- 
mas, thickened at the back ; the calyx with 2 of the sepals promi- 
nent at the base ; and the compressed seeds, disposed in a single 
row; will distinguish this from other genera, with accumbent 
cotyledons, in the same class and order. 
Two species British. 
MATTHI'OLA INCA'NA. Hoary Stock. Hoary Gillyflower. 
Spec. Char. Stem shrubby, upright, branched. Leaves spear- 
shaped, blunt, entire, hoary. Pods somewhat cylindrical, without 
glands.
