5. S. calycina, iV. J^. Br. Plant probably perennial, 1 ft. (or 

 more ?) high ; stem corymbosely branched, with its aagles and those of 

 the pedicels here and there scabrid-denticulate. Leaves in many pairs 

 along the stem, 6-10 lin. long, 4-9 lin. broad, orbicular-ovate, very 

 obtuse or slightly notched at the apex, very broadly rounded or sub- 

 cordate at the base, spreading, apparently thin, 5-7-nerved. Inflores- 

 cence rather lax, few-flowered, each branch with about 3 pentamerous 

 flowers ; pedicels 3-8 lin. long. Sepals leaf-like, 3-4 lin. long, 1 J-2 

 lin. broad, ovate or ovate-oblong, obtuse, narrowed at the base into a 

 very short petiole, reflexed or very spreading. Corolla-lobes 4-4J 

 lin. long, IJ- '^i lin. broad, elliptic-oblong, obtusely rounded at the 

 apex, apparently concave, with 2 oblong fringed glands near the base. 

 Stamens about 2 lin. long. Ovary ellipsoid, obtuse ; stigma sessile,

This species has the appearance of a Hypericum, and differs from all the other 

 African Swertias in its leaf-like reflexed calyx-lobes. 



6. S. fwambensis, N. E. Br. Perennial, 12-16 in. high; stems 

 simple and branching upwards or several and branched at the top ; 

 branches and stems long and straight, all ascending and forming a 

 nearly flat-topped corymbose inflorescence of many-flowered cymes. 

 Leaves in 4-6 distant pairs, J-lJ in. long, 2-5 lin. broad, lanceolate 

 or linear-lanceolate, acute, sessile, those at the base of the branches 

 largest, usually longitudinally folded, very spreading or deflexed, 

 those below smaller, almost passing into scales at the base, erect or 

 ascending. Pedicels J-l| lin. long. Sepals 2-3 lin. long, |-f lin. 

 broad, lanceolate, acute. Corolla-lobes 4J lin. long, Ij-lf lin. broad,
