3. Lobelia eryliae C.E.C.Fisch.

Plants lacking rhizomes. Stems suffruticose, 1.3 – 2.5 m tall, 6–14 mm diam, simple or branched above, erect, fistulose, glabrous to densely hispid. Leaves sessile, cauline; lamina narrowly elliptic or narrowly oblong, 3.5 –18 by 0.5 –2.5 cm, chartaceous or subcoriaceous, glabrous or hispid along the midrib on the abaxial or both surfaces; apex acuminate; base cuneate or attenuate; margin callose-serrulate or callose-denticulate. Inflorescence not clearly demarcated, 20– 85-flowered,sometimes branched at base; rachis sparsely hispid or scabrous; bracts linear or linear-elliptic, 10– 30 by 0.5 –2 mm, 1.2 – 2.5 times longer than their pedicel, glabrous or hispid along the midrib on the abaxial or both surfaces, acuminate at apex, the margin entire (rarely very sparsely serrulate); pedicels spreading or ascending, 6 –16 mm long, bibracteolate at or above middle, glabrous to densely hispid; bracteoles linear, 0.3 – 3 mm long. Hypanthium campanulate or obconic, 2.5 – 6 by 2 – 4.5 mm, glabrous or sparsely hispid toward base; base obtuse or acute. Calyx lobes subulate, linear, or linear-triangular, 5 –13 by 0.5 –1 mm, 1.2 – 4 times longer than hypanthium, erect or ascending, glabrous; apex acuminate; margin entire. Corolla violet, pale blue, mauve, or pink, rarely white, sub-bilabiate, 12–19 mm long, 3 – 6 times longer than hypanthium, externally glabrous or short-pubescent toward base, densely pubescent inside tube; tube straight, 4 –7 by 1.5– 3 mm, 1.5 – 3.5 times longer than broad, tapering slightly from base to mouth; dorsal lobes linear, 5–13 by 0.5 –1.1 mm; ventral lobes linear-triangular, narrowly elliptic, or elliptic, 5–14 by 1– 3 mm, connate for 1/4 to 1/2 or more their length, forming a lip 2.5– 6.5 mm wide. Staminal column exserted, emerging from corolla via its dorsal slit; filament tube 5.5 –10 mm, 1.5 –3 times longer than the dorsal anthers, glabrous or sparsely short-pubescent toward apex; anther tube grey, 1.3 –1.6 mm diam, glabrous or sparsely short-pubescent at base or dorsally toward apex; dorsal anthers 2.5 –4.5 mm long; ventral anthers 2 –3 mm long, bearded at apex with white trichomes 0.6 –2.2 mm long. Capsule oblong, ellipsoid, broadly ellipsoid or ovate, 5 –10 by 4 – 6 mm, the beak 1–2 mm; seeds amber-coloured, 0.4 –0.7 by 0.2 – 0.5 mm, broadly ellipsoid, compressed, the testa finely striate.

Distribution — Two subspecies, one on Luzon in the Philippines, the other on Sulawesi in Indonesia.
