508 lxiii. passiflore^: (masters). [Tryphostemma. 



Capsule subsessile, subcoriaceous, oblong*, glabrous, loculicidally 3- 

 valved; valves bearing- tbe placentas in the centre. Seeds large, 

 pendulous, included within a membranous aril; testa crustaceous, 

 pitted. — Erect or climbing 1 perennial herbs, with or without tendrils. 

 Leaves simple, alternate, stalked, stipulate. Flower-stalks axillary, 

 simple or tendril-like. Flowers small, greenish. 



A small genus, established by Dr. Harvey, on an erect species from Natal, in which 

 the perianth is 5- or 6-parted, and in the latter case the perianth seemingly in 2 rows. 

 In the Zanzibar species discovered by Dr. Kirk, the habit is that of the species of 

 Modecca, and the perianth is clearly in one row, though the segments are imbricate. 



1. T. zanzibaricum, Mast. A climbing tendril-bearing plant, with 

 slender smooth angular furrowed branches. Leaves alternate, stalked, 

 membranous, smooth, elliptic or lanceolate, subcordate or rounded at 

 the base, acute at the apex, serrulate, serratures sometimes glandular, 

 unicostate, 3-4 in. long-, 1-1J in. wide. Leaf-stalk slender, one-fourth 

 shorter than the blade, destitute of glands. Stipules linear, subulate, 

 persistent, much shorter than the leaf-stalks. Tendrils axillary, simple, 

 coiled in one direction only, thickened towards the apex, sterile or 

 floriferous. Flowers pedicellate ; pedicels very slender, somewhat 

 shorter than the flower, borne on tendrils and provided at the base with 

 3 stipule-like bracts. Calyx campanulate, 3-4 lines long, smooth, 

 deeply 5-cleft, lobes obtuse, many-nerved. Corona double, attached 

 to the base of the perianth, the outer one shorter than the sepals, upper 

 half fimbriate and lobulate at the edge ; lobules triangular, inflexed ; 

 inner corona half the length of the outer corona, everted at the edge, 

 and encircled at the base by a thick glandular ring. Filaments rib- 

 bon-like ; anthers included. Ovary sessile, ovoid • ovules numerous. 

 Styles 3, at the apex of the ovary ; stigmas capitate. Capsule an inch 

 in length, yellow, oblong, pointed. Seeds rather large, pitted, oblong, 

 enclosed within a white membranous aril. 



Mozamb. Distr. Zanzibar, Dr. Kirk! 



This species differs from the Natal plant described by Dr. Harvey, mainly in its 

 climbing habit ; the 6-parted 2-ranked perianth described by him not being a constant 

 character, many of the flowers being 5-parled, as in the Zanzibar species here de- 

 scribed. 



4. BASANANTHE, Peyr. ; Benth. et Hook. f. Gen. Plant, i. 812. 



Flowers dichlamydeous, hermaphrodite. Flower-tube very short. 

 Sepals 5, lobes oblong, originally imbricate. Petals 5, perigynous, 

 linear, withering, shorter than the sepals. Corona triseriate, the outer- 

 most series springing from the throat of the flower, tubular, membranous 

 below, dividing at the upper edge into two divisions, an outer and an 

 inner, the outer consisting of numerous fine erect or spreading fila- 

 ments, the inner of small inflexed pointed teeth ; the middle row of 

 the corona is either a fleshy ring or a spreading or reflexed membrane ; 

 the innermost row is a membranous cup encircling the base of the 

 stamens. Stamens 5, hypogynous, opposite to the sepals j filaments 

 distinct or connate at the extreme base, ligulate, erect j anthers adnate,
