Names
UTRICULARIA andongensis Welw. ex Kam. [family LENTIBULARIACEAE], in Engl. Jahrb. xxxiii. 104.
UTRICULARIA prehensilis Oliver var. parviflora [family LENTIBULARIACEAE], in Journ. Linn. Soc. ix. 150.
UTRICULARIA tortilis Kam. var. andongensis [family LENTIBULARIACEAE], in Engl. Jahrb. xxxiii 104.
Information
A delicate terrestrial annual growing in patches. Rhizoids filiform, branched, minutely glandular-verrucose. Leaves persistent at the time of flowering, in small rosettes of 3–6, linear, obtuse, narrowed at the base into a very short petiole, up to 15 lin. long and 1 lin. broad, frequently producing pitchers and rhizoids. Pitchers on the rhizoids and leaves, subglobose, 1/4 lin. long, inverted; upper lip divided almost to the base into 2 slender horn-shaped tentacles, curved over the orifice. Scape filiform to capillary, flexuous, 2 to more than 4 in. high; scales very few and minute. Flowers 1 or 2, distant; bracts and bracteoles subequal, lanceolate, acuminate, 3/4 lin. long; pedicel about 3 lin. long, capillary. Sepals broadly ovate in flower, upper larger than the lower, 1 3/4 to almost 2 lin. long, orbicular and acutely acuminate when ripe. Corolla yellowish, up to 4 1/2 lin. long (from the tip of the upper lip to the end of the spur); upper lip ovate-oblong, obtuse, slightly exceeding the upper sepal; lower lip orbicular, 2 lin. long, palate scarcely gibbous, smooth; spur conical, acute, 2 1/2 lin. long, straight or nearly so. Anthers slightly over 1/4 lin. long; filaments filiform, 1/2 lin. long. Stigma sub-sessile; upper lip indistinct; lower short, broad, truncate. Capsule and seeds unknown.
Distribution
Gaboon Lower Guinea Sierra del Crystal; on rocks in rivers, Mann, 1684!Angola Lower Guinea Pungo Andongo; boggy places by the Casalate River, on the steep slopes of Pedra Songue, 3000 ft., Welwitsch, 264!
Notes
No doubt, more nearly allied to U. tortilis than to U. prehensilis; but sufficiently distinguishable by the persistent leaves, much broader and more conspicuously acuminate sepals, larger corollas, with an ovate-oblong upper lip and filiform filaments.
