Erysimum schlagintweitianum O. E. Schulz

It is a very little and incompletely known species, and may not be specifically different from the previous species and may be only a dwarf form of it. Mature siliquae are not yet known.

Biennial or perennial, up to 10 cm tall, erect, simple or rarely branched from the base; hairs 2-4-partite appressed; rootstock slender, elongated, simple. Radical leaves densely rosulate, narrowly oblanceolate, 20-30 mm long, 2-5 mm broad, sinuate-dentate to sub-entire stalked to subsessile; cauline leaves few (2-3 usually), linear, almost entire, sessile, smaller. Racemes 10-20-flowered. Flowers c. 5 mm across, yellow; pedicels 2-5 mm long in young fruits, lowermost sometimes bracteate. Sepals 4-6 mm long. Petals 8-10 mm long, 2 mm broad. Stamens c. 5:7 mm long; anthers c. 2 mm long. Ovary 30-36-ovuled; style c. 1 mm long with capitate, sub-bilobed stigma. Siliquae (immature) c. 35 mm long, 1 mm broad, subcylindrical, linear, appressedly hairy.

Herbs annual or biennial, 3-10 cm tall. Trichomes malpighiaceous mixed with 3(or 4)-forked ones. Stems erect, simple at base. Basal and lowermost cauline leaves subrosulate; petiole 2-7 mm; leaf blade narrowly oblanceolate, flat, 0.7-3 cm × 2-7 mm, base attenuate, margin sinuate-dentate or dentate, apex acute. Upper leaves subsessile, usually smaller than basal, predominantly with 3-forked trichomes adaxially, entire or dentate. Racemes corymbose, densely flowered, ebracteate, elongated in fruit. Fruiting pedicels divaricate, 2-6 mm, stout, narrower than fruit. Sepals linear-oblong, 4-6 × ca. 1 mm. Petals yellow, spatulate, 7-10 × 1.8-2.5 mm, apex rounded; claw subequaling sepals. Filaments yellow, 4.5-6.5 mm; anthers linear-oblong, 1.5-2 mm. Ovules 30-40 per ovary. Fruit narrowly linear, subterete, 2-3.5 cm × ca. 1 mm, somewhat torulose, divaricate-ascending, straight or curved upward; valves pubescent outside with malpighiaceous and 3(or 4)-forked trichomes, glabrous inside; style stout, 1-2 mm, cylindric, sparsely pubescent; stigma entire or slightly 2-lobed. Mature seeds not seen. Fl. Jun-Jul, fr. Jul-Aug.
