Key for Abolboda Kunth

1Plants low, delicate and tufted, often moss-like, inflorescence either sessile or raised on a bractless scape no longer than 15-20 cm; spread corolla no broader then 1.2 cm, pale blue to white.
1'Plants taller, inflorescence raised well above leaves on a scape rarely as low as 15 cm, this with at least 1 pair of erect scape bracts; spread corolla 1.5 cm wide or more, bright blue to violet.
2Scape present, though frequently exceeded by leaves.
2'Scape lacking or short, inflorescence sessile or subsessile.
3Leaf blades flattened, soft, elongate-linear, tip acute, short-acuminate or apiculate; lateral sepals (when spread) broadest at middle or above, emarginate, mucronulate; stylar appendages narrowly linear-clavate, declinate; capsule apex smooth or nearly so; seeds minutely papillose.
3'Leaf blades thickened, variously angled, lunate or trigonous in cross-section, tapering to an abruptly blunt, setaceous-awned tip; lateral sepals broadest below middle, the apex tapered, not emarginate; stylar appendages much broadened distally, ascending or spreading-ascending; capsule apex papillose; seeds not papillose.
4Leaves, or some of them, granular-papillose or tuberculate-scabridulous; spike under 1 cm long; lateral sepal keel variously scabridulous or papillose; stylar appendages declinate, narrow.
4'Leaves smooth throughout; spike ca. 1 cm long; lateral sepal keel smooth; stylar appendages ascending, much broadened distally.
5Spikes broadly ellipsoid to ovoid or even globose or hemispheric; sepal tips atte- nuate to sharply acute, much projected beyond tip of subtending bract, keel often excurrent as a cusp or arista.
5'Spikes narrowly ellipsoid, lanceoloid or cylindric; sepal tips acute, only slightly projected beyond tip of subtending bract, keel tip lacking a cusp or arista.
6Leaf blades at their widest fully 1 cm wide, usually wider; scape bracts mostly 2 or more pairs; lateral sepals strongly curved, much longer than their subtending bract; stylar appendages lacking basal auricles; seed ribs strongly connected by cross-ribs
6'Leaf blades at their widest mostly 5 mm wide or less; scape bracts a single pair; lateral sepals variously longer than their subtending bract; stylar appendages with basal auricles; seed ribs not strongly connected by cross-ribs.
7Lowest (largest) pair of scape bracts mostly 2-3 (-3.5) cm long; spikes broadly ovoid to hemispheric or subglobose, rarely over 2 cm long.
7'Lowest (largest) pair of scape bracts (3-)3.5-6 cm long; spikes broadly ovoid to ellipsoid or narrowly ovoid, mostly 2.5 cm long or longer.
8Leaf blades mostly elongated-linear, abruptly narrowed apically, their margins thickened; spikes many-flowered, bracts subulate-aristate; caosule valves sharp-tipped.
8'Leaf blades mostly tapering gradually from base to tip, their margins thin; spikes few-flowered, bracts tipped by a short, stout, blunt mucro; capsule valves blunt-tipped, slightly retuse.
9Scapes mostly with 2(-3) pairs of bracts, these 1.5-3 cm long plants usually not over 6 dm high.
9'Scapes mostly with but 1(-2) pairs of bracts, these 4-6 cm long; plants mostlv 6-10 dm high.
