Drege ! Cradock, and Gamke R., Zeyher / (fragments). (Herb. Sd., Hk,, Bth., D.) 
A small plant, with stems 2-3 inches long, resembling Sedum dasyphyllum in habit 
and foliage. Branches jointed, slender. Leaves 1-11 lines in diameter. Flowers 
small, on pedicels 2-3 lines long. Fragments of a nearly similar but stronger plant 
were gathered by Zeyher at Bitterfontein ; they differ from Zeyher’s plant above 
in having a large woody root and somewhat larger leaves, but are too im- 
perfect for description. 
68. C. dentata (Thunb! Cap. 293); stem herbaceous, simple or 
forked, with distant nodes ; leaves opposite or subfasciculate, on very 
long petioles, reniform, at base either cordate or cuneate, repando-crenate 
or lobulate, or subentire, thinnish, membranous when dry, glabrous ; 
flowers patently cymose, on slender pedicels, the lower ones sometimes 
crowded in the axils ; calyx lobes short, blunt, oblong, glabrous; petals 
free, ovato-lanceolate, acute. £. ¢ Z./ 1857; also Petrogeton typicum,

Dr. Pappe! (Herb. Thunb., Hk., D., Sd.) 
A weak, soft, succulent herb, with something the habit of Chrysosplenium oppositi- 
folium, variable in size, 3-6 incheslong or more. Petioles 1-3 inches long, slender. 
Leaves 4-1 inch wide, shorter than their width, occasionally smaller or larger: in 
the smaller forms subentire ; in the larger with a few wide crenatures or very shal-. 
low lobules. Flowers 2 lines long, starlike, in a more or less developed cyme. 
69. C. patens (E. & Z.! 1855); stem herbaceous, simple or forked, with 
distant nodes, slender and pellucid; leaves opposite or subfasciculate, 
on very long petioles, roundish-reniform, obtuse at base, repando-dentate 
or lobulate, thin and membranous when dry, glabrous ; flowers in a 
spreading, slightly divided cyme, on long slender pedicels ; calyx-lobes 
very short, linear-oblong, acute, one-nerved ; petals free, ovato-lanceolate,

Scarcely differing from the preceding except by the calyx and the more sharply 
lobulate or subincised leaves, and laxer inflorescence. 
70. C. nivalis (E. & Z.! 1860) ; stem herbaceous, simple or forked, 
with distant nodes, slender and pellucid ; leaves opposite or subfascicu- 
late, on long petioles, subrotund, entire, or obscurely repand, thin and 
membranous when dry, glabrous; flowers on very long threadlike pedi- 
cels, axillary or terminal, or 2—3 together in an imperfect cyme ; calyx- 
lobes nearly equalling the petals, thin, elliptic-oblong, obtuse, nerved ; 
petals ovate or ovate-elliptical, acute ; styles shortly subulate. Petro-
