Resurrection of the genus Camelinopsis (Brassicaceae, tribe Thlaspideae); with introduction of a new species

Abstract

The ditypic genus Camelinopsis was recently subsumed into Pseudocamelina . However, we here show that the type species of the genus, Camelinopsis campylopoda is distinct from Pseudocamelina , and should be recognized as a separate genus. The second species C. kurdica , however belongs to the genus Pseudocamelina . Camelinopsis differs from Pseudocamelina mainly by its subglobose to broadly obovoid, slightly flattened silicle which is 1.8–2.6 mm wide, instead of a linear, narrowly ellipsoid, occasionally oblong to obovoid silique, that is never wider than 1.5 mm. In addition, seeds of Camelinopsis are mucilaginous when wetted while seeds of Pseudocamelina are not. A new species of Camelinopsis is also described and illustrated based on new collections from western Alborz Mountains, northern Iran. This novelty, C. alborzica , is readily distinguished from C. campylopoda by its biennial (versus annual) habit, straight (versus strongly flexuous) racemes, longer sepals (1.7–2.1 versus 1.2–1.5 mm), shorter fruiting pedicels (0.5–1 versus 1.5– 4 cm) and higher ovule number (8 versus 4 per ovary). The genus Camelinopsis is considered a low mountain relative of the high‐elevation genus Didymophysa , as indicated by an ITS phylogeny.
