Pseudocamelina kermanica Esmailbegi, Mirtadzadini & Al-Shehbaz , sp. nov.

Diagnosis:— Pseudocamelina kermanica is easily distinguished from the other annual species of the genus by having straight fruiting pedicels, 8 ovules per ovary, and strongly dentate, flabellate to suborbicular-cordate or broadly obovate basal leaves.

Type:— IRAN. SW Kerman: Qale-Askar , 3 km SW of Madun village, N29 32.231, E56 34.008, 3530 m, 15 June 2012, Mansour Mirtadzadini 1782b (holotype, MIR!; isotype, MO-6737248!). Fig. 2 .

Description:—Herbs annual, Stems 40–45 cm tall, slightly flexuous from lowermost branching, profoundly flexuous in the inflorescence. Basal and lowermost cauline leaves with petiole 0.8–2.5 cm long; blade somewhat fleshy, flabellate to broadly obovate or suborbicular-cordate, 0.7–2.2 × 1–3 cm, with 10–20 obtuse deep teeth, base truncate to cordate or cuneate; cauline leaves reduced in size and fewer toothed upwards; uppermost leaves linear to linear-oblanceolate, entire. Racemes rather lax, 7–15-flowered, grouped in open panicles; rachis strongly flexuous, segments between flowers distinctly shorter than fruiting pedicles; fruiting pedicles 7–14 mm long, filiform, straight, divaricateascending at 40–60º angle. Sepals narrowly oblong, purplish, 1.5–2 mm long, spreading; petals purplish with white margin, spreading, narrowly oblanceolate 2.5–3 × 0.7–1 mm; stamen spreading; anthers yellow, ca. 0.5 mm long; ovules 8 per ovary. Fruit oblong to oblong-ovate, 1.8–3.5 × 1–1.5 mm, terete; valves smooth, not veined, papery, obtuse at both ends; gynophore 0.1–0.3 mm long; septum complete; style slender 0.8–1 mm long. Seeds oblong, plump, 1–1.2 × 0.5–0.7 mm.

Eponymy: The species epithet is derived from Kerman province of Iran.

Notes:—In the annual habit, strongly flexuous racemes in open panicles, silicle fruits, filiform pedicels longer than rachis segments between pedicels, undivided upper leaves, and lack of indumentum, Pseudocamelina kermanica resembles both P. campylopoda and P. kurdica , or Camelinopsis sensu Miller (1978) and Al-Shehbaz (2012). Such strong similarities support the reduction herein of the latter genus to synonymy Pseudocamelina . However, P. kermanica differs from both species in having 8 (vs. 4 or 2) ovules per ovary, undissected (vs. 1–3-pinnatisect) basal leaves, and straight (vs. strongly recurved) fruiting pedicels.

Description:—Herbs perennial, with slender, surculose, rhizome-like subterraneam caudex, glabrous or with a few simple trichomes, subglaucus. Stems (5 −) 7 − 15 cm tall, dichotomously branched from base and above, ascending, flexuous. Basal leaves rosulate, fleshy, petiole 1 − 2.5 cm long; blade obovate, (5 −)6 − 14 × 2.2 − 8 mm, entire, cuneate at base, obtuse at apex; cauline leaves linear-oblanceolate, short petiolate, reduced in size upward. Racemes several flowered, lax, flexuous; fruiting pedicels divaricate, straight, 4 − 10 mm long. Sepals oblong, purple, 3.8 − 4 mm long, ascending, lateral pair saccate at base; petals oblong, obtuse, violet, 5.2 − 6 × 1.5 − 2 mm, undifferentiated into blade and claw, obtuse at apex; median filaments 3.9–4.1 mm long, lateral filaments, 2.8–3 mm long; anthers oblong, ca. 1 mm long, not apiculate; ovules 18 − 28 per ovary. Fruit linear, 20 − 25 × 1 − 1.3 mm, slightly torulose, midvein obscure; style 0.2 − 0.5 mm long. Seeds oblong, uniseriate, smooth, oblong, 1.2 − 1.7 × 0.8 − 0.9 mm.

Distribution:—endemic to Iran.

Notes:— Rechinger (1973) compared Pseudocamelina kleinii with P. violacea , both of which species were reduced by Miller (1978) to synonymy of the highly variable P. glaucophylla . However, Miller annotated the type specimen of P. kleinii as “Rather long, torulose fruited form with large fls”. In fact, P. kleinii differs substantially from P. glaucophylla by being a much smaller plant (5 −)7 − 15 vs. (25 −) 30 − 70 cm tall with saccate (vs. non-saccate) lateral sepals, violet (vs. white) petals 5.2 − 6 (vs. 3.5 − 4.5) mm long, 18 − 28 (vs. 10 − 20) ovules/seeds per ovary/fruit, and fruits 20 − 25 [vs. (3 −)5 − 18(− 25)] mm long. In our opinion these substantial differences strongly justify the recognition of P. kleinii as an independent species. Furthermore, P. kleinii is a surculose perennial (vs. biennial).
