Names
Sisymbrium dissitiflorum [family BRASSICACEAE]
Information
Plants glaucescent, glabrous. Rhizomes thick, woody, with several stems 30-50 cm high. Leaves slightly ciliate; lower stem leaves oblong-obovate, obtuse, pinnatifid at the base and narrowed into a short petiole; upper leaves shortly petiolate, runcinate-pinnatifid, acute, with unequal, narrowly triangular, acute, entire or dentate lobes. Raceme lax, the buds overtopping the open flowers. Pedicels 4-6 mm long, wide-spreading. Sepals 3-4 mm long, yellowish. Petals yellow, 5 mm long, broadly oblong with a broad hyaline claw. Ovary 56-ovulate. Siliquae 3-5-4 cm long, on pedicels 7-9 mm long. Otherwise like S. capense. The description is derived largely from O. E. Schulz, 1.c.
Habitat
The above specimen agrees well with the de­scription. It is from the same locality as two of those cited by Schulz and is completely glabrous and glaucous, with only a few young buds; the upper stem leaves are shortly petiolate, oblong-lanceolate to lanceolate, the lobes small, narrowly triangular, entire or dentate. Herre in STE 19059 from Besonder-meid, Steinkopf, another imperfect specimen, probably belongs here too. More material is req jired before the position of the species can be evaluated.
