25. LINDENIA Benth. PI. Hartw. 84. 1841.* 



Shrubs, glabrous or pubescent, the branches terete. Stipules interpetiolar, short, connate, 

 cuspidate, subpersistent. Leaves opposite, short-petiolate, narrow. Flowers large, showy, 

 in few-flowered terminal cymes, short-pedicellate; bracts subulate; hypanthium elongate-turbi- 

 nate, 5-angulate or 5-costate; calyx 5-lobate, the lobes elongate-subulate or lanceolate, 

 equal or unequal, persistent; corolla salverform, white, the tube terete, much elongate, the 

 throat naked, the limb 5-lobate, the lobes oblong, spreading, contorted in bud. Stamens 5, 

 inserted at the top of the corolla-tube; anthers sessile, linear-oblong, obtuse, recurved, exserted. 

 Disk annular. Ovary 2-celled ; style filiform, bifid, pilose, the lobes erect ; ovules very numerous, 

 crowded, the placentae semicylindric, stipitate, longitudinally adnate to the septum. Capsule 

 clavate or pyriform, 2-celled, septicidally bivalvate, many-seeded, the valves bifid, often 

 elastically coiled after dehiscence. Seeds small, angulate, smooth; endosperm fleshy; embryo 

 clavate, the radicle terete. 



Type species, Lindenia rivalis Benth. 



1. Lindenia rivalis Benth. PI. Hartw. 84. 1841. 



Lindenia acutiflora Hook. Ic. pi. 475. 1842. 



Shrub, 3-10 dm. high, the branches stout, dark-brown or reddish-brown, usually pilosulous 

 when young, sometimes glabrate; stipules annular, 3-5 mm. long, the lobes subtruncate to 

 acute, cuspidate, thin, brown, glabrous or pilosulous; leaves crowded at the ends of the branches, 

 the petioles stout, 2-10 mm. long, usually pilosulous, the blades oblanceolate to linear-elliptic, 

 3.5-16.5 cm. long, 0.7-2.8 cm. wide, attenuate or long-attenuate at the base, acute to attenuate 

 at the apex, thin, bright-green, glabrous above or minutely pilosulous along the costa, the 

 venation plane or subimpressed or the costa prominulous, beneath scarcely paler, densely 

 or sparsely puberulent or pilosulous, rarely quite glabrous, the venation prominent, the 

 lateral veins 6-12 on each side, ascending at an angle of 45° or less, arcuate, extending to the 

 margin, this plane or revolute; cymes mostly 3-flowered, the peduncles short, stout, the pedi- 

 cels very stout, 1 cm. long or shorter; hypanthium 7-10 mm. long, sparsely or densely hirsutu- 

 lous, calyx-lobes linear-subulate, 1-2 cm. long, green, erect, pilosulous or hirsutulous; corolla- 

 tube usually 10-16 cm. long, 2.5-3 mm. thick, copiously pilosulous outside, the lobes elliptic 

 to oblong-oval, 2.5-3 cm. long, acute to very obtuse at the apex, short-pilosulous; anthers 

 linear, about 1 cm. long; capsule pyriform, 1.2-2 cm. long, costate, hirsutulous, thick and 

 woody, the exocarp finally separating from the endocarp; seeds 1.5-2 mm. long, brownish. 



* The name Sipkonia was first suggested by Bentham for this genus, and was printed in the text of 

 the fascicle of Plantae Hartwegianae containing page 84. Before the publication was distributed, 

 however, the name Lindenia was substituted, with a pen, in all the copies. There is no reason, con- 

 sequently, for citing the homonymous Siphonia Benth. as a synonym of Lindenia, for the former was 

 never published, except as it has since appeared in synonymy.
