2. GENLISEA, St. Hil.; Benth. et Hook. f. Gen. PI. ii. 988. 
Calyx deeply 5-partite, persistent; segments equal or subequal, 
ovate to lanceolate. Corolla 2-lipped, spurred ; upper lip erect, entire 
or emarginate ; lower lip larger than the upper, with a vaulted more 
or less 2-gibbous palate and a deflexed 3-lobed margin. Stamens 2 ; 
filaments curved, short, sometimes asymmetrically winged; anthers 
dorsifixed, cells subdistinct or confluent ; pollen globose, smooth with 3 
pores. Ovary more or less globose, 1-celled ; style short or very short ; 
stigma 2-lipped, anticous lobe much larger than the posticous; ovules 
numerous, sessile on the free central fleshy placenta, anatropous. Capsule 
usually globose, circumscissile or breaking up irregularly. Seeds ovoid, 
often very oblique, exalbuminous ; testa subtransparent, spongy, sub- 
bullate. Embryo hippocrepiform (always?), not differentiated.— 
Rootless, terrestrial annual (?) herbs, growing in swamps, with peculiar 
pitcher-like organs (modified leaves) for the capture and digestion of 
small organisms. Primary axis terminating with an inflorescence, pro- 
ducing at the base often very dense rosettes of leaves and frequently 
root-like organs (rhizoids), the latter from the axis or the base of axillary 
buds. Leaves heteromorphic ; foliage leaves petioled, entire, spathu- 
late to suborbicular, persistent at the time of flowering ; pitcher-leaves 
consisting of a stalk and a slender tube, cylindric from an ellipsoid 
base and passing into 2 long ribbon-like spirally twisted arms, the arms 
and tube provided on the inner side with transverse bands of stiff 
reversed hairs and the tube also with digestive glands. Inflorescence 
racemose, bracteate, peduncled ; lower bracts usually barren, adpressed ; 
bracteoles 2, at the base of the pedicel. 
Species about 7-8, one species in South Africa, the others in Tropical South 
America. 
A barren plant collected by Welwitsch in Angola and numbered 6743, is 
referred to by Hiern in Cat. Afr. Pl. Welw. i. 789 as being possibly a species of 
Genlisea, 1t does not belong to Lentibulariee. 
Inflorescence and ovary densely glandular-puberulous . 1. G, afrieana. 
Inflorescence hispidulous or glabrous ; ovary glabrous or 
densely pubescent. ee 
Ovary densely pubescent above the glabrous base. 2. G. hispidula, 
Ovary quite glabrous. . . ° 3. G. subglabra. 
1. G. africana, Oliver in Journ. Linn. Soc. ix. 145, partly. 
Leaves numerous ; blades spathulate-cuneate, 2-3 lin. long, 1-1} lin. 
broad, gradually narrowed into the petiole, 2-5 lin. long. Utricles 
very variable in size; tube 3-7 lin. long. Scape erect, up to over 1 ft. 
long, filiform, simple, or with a branch from the lower part, copiously 
glandular-puberulous, at length glabrescent near the base, with a few 
remote barren bracts in the lower part; raceme densely glandular- 
puberulous all over, 3—6-flowered; bracts ovate, up to $ lin. long ; 
bracteoles similar; pedicels filiform, obliquely erect or ascending, 4-5 
lin. long. Calyx-segments subequal, lanceolate-ovate, acute, 7-8 lin. 
long. Corolla pale purple, drying blue, about 4 lin. long; upper lip
