TETR ADYNAMIA— 81 LIQUOS A. Matthiola. 205 



sliallow notch ; claws erect, the length of the calyx. Fi- 

 lam. awl-shaped, simple, distmct ; 2 outermost much the 

 shortest, embraced at the bottom by a nectariferous gland. 

 ^??//z. oblong-arrow-shaped, nearly erect, of 2 linear lobes. 

 Germ, oblong, rather compressed, shorter than the sta- 

 mens. Style short and thick, or more frequently want- 

 inof. Stis^ma of 2 converging lobes, either thickened or 

 protuberant at the back, permanent. Pod linear, com- 

 pressed, or nearly cylindrical, convex or keeled at one 

 or both sides ; valves straight ; partition membranous. 

 Seeds ranged alternately in a single row, orbicular, com- 

 pressed, generally encompassed by a membranous bor- 

 der ; cotyledons flat, accumbent. 

 Herbaceous or shrubby, almost always hoary, with starry 

 pubescence, occasionally intermixed with stalked glands. 

 Leaves oblong, undivided, toothed, or sinuated. Fl. 

 fragrant, especially in an evening, their colours purple, 

 white, greenish, or brownish. Mr. Brown remarks that 

 when the lobes of the stigma are thickened at the back, 

 the cotyledons are incumbent. Prof. DeCandolle on the 

 contrary declares that he never met with incumbent co- 

 tyledons in any species examined by him. In our native 

 ones they are certainly accumbent. — I beg leave to ob- 

 serve that the name of the botanist here commemorated 

 is Matthiolus, not Mathiolus.
