Description:—Rhizomatous herbs forming dense tufts, with usually deciduous aerial structures. Rhizome small, inconspicuous, clothed with persistent fibrous leaf bases, sometimes bristly; roots numerous, swollen, fleshy, tuberous. Stems aerial, simple or 1-branched, solid, ± rounded in cross section, usually shorter than leaves, sometimes inconspicuous or absent. Leaves isobilateral, equitant, ensiform to linear, with 1–3 prominent ribs,

usually stiff, not fetid. Flowers solitary or in small groups, terminal, pedicellate. Spathe valves 2–3, herbaceous with scariose margins at anthesis, ± keeled. Perigone in 2 rows, differing in size and shape, fused in a long, slender, cylindrical tube, somewhat widened at the apex; falls erect to erect-patent, obovate-cuneate to broadly lanceolate, sometimes with slightly undulate margin, reflexed in the upper part, gradually tapering into a short claw, with a prominent central undulate or irregularly fringed crest of a single row (rarely vestigial), usually with coloured fimbriae; standards erect to patent, narrowly oblong to elliptic, about equalling the length of falls, sometimes with slightly undulate margin, narrowed into a subcanaliculate, long haft. Stamen filaments free, adnate to the fall bases. Ovary trilocular, with axile placentation. Style filiform, with 3 petaloid branches, about half longer than falls, each one concealing a stamen; crests long, straight, broadly triangular, sometimes with fimbriate margins; stigma bilobed, with broad lobes. Capsule ellipsoid to ovoid, with 6 ribs, trigonous, dehiscing from apex to about middle, with sharp ribs, shortly pointed at the apex, not hidden into spathes; pericarp papery. Seeds numerous, oblong to pyriform, brownish, with a conspicuous whitish aril; testa surface wrinkled. p = 7 or 9. Figs. 3L , 6O , 13C .

It includes at least 8 species occurring in the central parts of Asia, south of the main Himalayas ( Fig. 9D ). A poorly known group, still in need of further studies. The noteworthy species Junopsis staintonii shows some morphological peculiarities allowing description of a new section, of which that species is the only known representative so far: Junopsis sect. Staintonia M.B.Crespo, Mart. -Azorín & Mavrodiev, sect. nov. Type (holotype):— J. staintonii (H.Hara) M.B.Crespo, Mart. -Azorín & Mavrodiev [≡ Iris staintonii H.Hara ]. Plantae humiliores notabilis ab typica sectione praecipue differt foliis basalibus brevioribus 1–6 cm longis, cujus una usque ad 30 cm postea multo elongata; floribus minutis, tubo breviore 20–25 mm long., segmentis perigonii minoribus, exterioribus obovato-subspathulatis, angustioribus, imberbibus, crista centrali minuta vestigiali, subintegra munitis. Species unica hujus sectionis per Nepalem reperta est.
