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 subclistinct 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. It does not belong to Lentibula? , iece.

Inflorescence hispidulous or glabrous ; ovary glabrous or 

 densely pubescent. 

 Ovary densely pubescent above the glabrous base . 2. G. hispidula. 

 Ovary quite glabrous ... . 3. G. subglabra. 



1. G. africana, Oliver in Joum. Linn. Soc. ix. 145, partly. 

 Leaves numerous; blades spathulate-cuneate, 2-3 lin. long, \-\\ 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 f 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
