Species

Angiosperms > Boraginales > Boraginaceae > Myosotis

Characteristics

Rosettes few or many, lvs obovate-to lanceolate-spathulate, 3-12 × 0.6-2 cm., narrowing rather abruptly to subacute tip and gradually to broad petiole almost as long as lamina; hairs tapering and flexuous, appressed or spreading, on undersurface shorter, sparser, often appressed, retrorse except sts at tip. Lateral branches few per rosette, ascending to erect, up to 30 cm. long, internodes us. < lvs. Stem-lvs decreasing upwards, lower ones oblong, uppermost c. 2 × 0.6 cm., lanceolate with truncate base and subacute tip; hairs long, fine, us. crowded and appressed on upper surface, on undersurface sparser, shorter and more spreading, often retrorse towards base of lower stem-lvs. Cymes ebracteate, us. simple or once branched, 8-fld, up to 7 cm. long in fr., internodes < calyx in fr.; pedicels very short. Calyx 6-8-(9) mm. long, lobes us. slightly > 1/2 length, obtuse, rather broad; hairs long and spreading near top, medium and hooked about middle, short and spreading or retrorse near base, short appressed hairs throughout. Corolla yellow to brownish orange, narrow-funnelform, 6-8 mm. diam., tube up to 10 mm. (occ. 15 mm.) to level of scales, more to sinus of lobes; scales small or absent, sts variously developed in one fl., lobes rounded, c. 3 × 2.5 mm., not widely spreading; filaments broad, fixed just below scales (if any), c. = anthers which are 1·5-2·2 mm. long and wholly above scale-level; style at least 2 × calyx in fr., stigma capitate. Nutlets oblong, c. 3 × 1·5 mm.
