Species

Angiosperms > Boraginales > Boraginaceae > Myosotis

Characteristics

Erect or sprawling herb, possibly annual, with adventitious roots from amongst rosette-lvs only. Rosette-lvs (1)-3-4 × (0.6)-1-1·5 cm., lamina orbicular, mucronate, petiole much longer, sharply defined, slender; hairs short, stiff, sparse, appressed, on undersurface similar but fewer. Lateral branches ascending to erect, up to 30 cm. long, sts themselves repeatedly branched; internodes mostly > lvs, hairs short and closely appressed. Stem-lvs with orbicular laminae, petioles becoming progressively shorter and broader; lvs associated with fls almost sessile, very broadly ovate, up to 10×6 mm.; hairs as on rosette-lvs. No clearly defined cyme but about 6 fls produced over a length of up to 10 cm., us. but not always above the highest branch, each fl. opp. or slightly below a If. Pedicels long, = fl. and 2-3 × calyx in fr. Calyx 2-3 mm. long, very deeply divided, lobes narrow and spreading in fr. exposing nutlets; hairs short, stiff, appressed, confined to margins and midribs of lobes, crowded on base. Corolla white, 5-8 mm. diam., very openly campanulate, tube 1·5 mm. long with small scales, lobes oblong, c. 2.5 × 1·5 mm.; filaments fixed below scales, as long as lobes; anthers c. 0·5 mm. long; style 2 × calyx in fr., stigma conspicuously capitate. Nutlets up to 2 × 1·5 mm., broadly ovate, brown.
