182 Lxxxiv. APOCYNACE^ (stapf). [CaUichiUa. 



terminal; peduncles 1J-4J in. long, sometimes paired on a common 

 peduncle ; rhachis at first very short, then lengthening, ultimately up 

 to 1-J in. long, bearing the persistent, somewhat distant bracts and 

 scars of the fallen flowers, bracts ovate, acute, up to IJ lin. long; 

 pedicels slender, up to G lin. long. Sepals unequal, oblong, obtuse, 4-5 

 lin. long. Corolla-tube slightly over 1 in. long, cylindric up to 6-7 lin. 

 from the base, then subcylindric or very slightly and gradually widened 

 towards the mouth, here 2-3 lin. in diam. ; lobes obliquely obovate and 

 acuminate, cuneate below, up to Ij in. long, almost 1 in. broad. 

 Stamens inserted 7-8 lin. from the base ; anthers 2 lin. long. Style 

 6-7 lin. long ; stigma shortly cylindric, bifid, with a wavy, lobed ring 

 at the base.

Very similar to C. ina;qualis, from which it differs only in the more attenuate or 

 even acute (never cordate) leaf-bases, in the larger calyx and- the corolla-lobes, 

 being comparatively longer and more narrowed towards the base. 



3. C. inaequalis, Stapf. A glabrous, scandent shrub ; branches 

 slender, greenish, terete. Leaves subsessile, oblong-elliptic to obovate- 

 oblong or oblong, abruptly and acutely acuminate, rounded or sub- 

 cordate at the base, 5-8 in. long, 1J-3J in, broad, papery ; midrib 

 slender ; secondary nerves 7-9 on each side ; veins distinct or obscure, 

 forming a loose network ; petiole hardly any or pp to 2 lin. long, 

 stout. Inflorescences 2-7-flowered (often with only 1 flower out at a 

 time), racemiform on very slender pseudo-axillary peduncles 2-5 

 in. long ; rhachis at first very short, then lengthening to ^ in. long, 

 covered with the persistent bracts and scars of the fallen flowers; 

 bracts very broad, ovate, J-J lin. long, margins scarious ; pedicels 

 slender, up to 6 lin. long, bracteolate at the very base. Sepals 

 unequal, ovate, obtuse, 1|-2J lin. long. Corolla-tube 1-1^ in. long^ 

 cylindric to 7-8 lin. above the base, then gradually widened towards 

 the mouth ; lobes very broad, obliquely obovate and acuminate, 1 in. 

 long and almost as broad. Stamens inserted 6-7 lin. above the base ; 

 anthers 2 to scarcely 2 J lin. long ; style about 6-7 lin. long ; stigma 

 subulate, papillose, bitid, with a lobed wavy ring at the base. —

4. C. subsessilisy Stapf. A climbing or erect shrub, or small 

 tree, quite glabrous ; branches slender, terete or quadrangular when 

 quite young, pale green, ultimately whitish. Leaves oblong to lanceo- 

 late, acuminate (acumen slender and acute), narrowed towards and 

 generally suddenly contracted at the base, 3-7 in. long, 1-2 J in. broad, 

 membranous or papery ; secondary nerves about 8 on each side ; petiole 

 very short or 0. Inflorescences few-flowered or reduced to 1 flower ; 

 peduncle rather slender, 1 J-4 in. long; bracts ovate-acute, 1-2 lin. long ; 

 pedicels 2-6 lin. long. Calyx 3-5 lin. long ; sepals oblong, obtuse or
