Hydrocotyle. | UMBELLIFERZ (Sond.) 531 
Stem and branches woody, 4-14 feet, erect. Petioles 1-2 inches long. Leaves 
about 1 inch long, 6-8 lines broad, sometimes narrower, attenuated at the base ; 
teeth or lobes at the apex 1-3 lines long. Peduncles 4-6 lines long. Flowers very 
small. Fruit 14 lines long, compressed ; mericarps with 3 ribs on each side ; fur- 
rows flat, not wrinkled. 
13, H. montana (Cham. & Schlecht. 1. c. 374); suffruticose, swbto- 
mentose, at length glabrescent ; stems suberect; branches spreading, 
elongate ; leaves ovate or elliptic-oblong, acute, entire or acutely-3—5- 
_ toothed at the apex, coriaceous, 3—5-nerved, obtuse or subcuneate at the 
base ; those of the branches smaller, sublanceolate, much shorter, 
petiolated ; umbels sessile, many-flowered, monocarpous ; petals of the 
fertile flowers hairy on back ; fruit obovate-orbicular, glabrous, shorter 
or longer than the villous, ovate, cuspidate, 2-leaved involucre. H. 
difformis, E. § Z.1 2165. Zey. 2666. 
Has. Mountains near Langekloof and Tradow, Mundt § Maire; Hottentotts- 
hollandberge near Grietjesgat on Palmietriver, near Klynriver, and between Gna- 
denthal and Mount Zwarteberge, Z.¢ Z./ May. Aug. (Herb. Berol. Hk. Sd.) 
Root thick and woody. Stem and branches striate, purplish, several feet long. 
Leaves much aggregated at the base and on the nodes, on carinate, 2—5-uncial 
petioles, usually 1-2 inches long, 8—14 lines broad ; old ones sometimes nearly 4 
inches long, 2 inches broad, very thick and with revolute margins ; those of the 
upper branches nearly sessile, 1-4 inch long, 4-2 lines wide. Umbels capitate, 
woolly, 10-20-flowered ; sterile flowers on filiform, villous pedicels, the fertile quite 
sessile. Petals white and violaceous, obtuse. Fruit 2 lines long and broad, quite 
glabrous ; mericarps with 2 ribs on each side, very prominent as well as the dorsal 
rib ; furrows flattish or rugose. The lower leaves are similar to those of H. 
triloba, but the base is ovate, obtuse, rarely subcuneate. The specimens collected 
by Mundt. § Maire are not very perfect. 
14. H. tridentata (Linn. fil. Suppl. 176); suffruticose, villous- 
tomentose, at length glabrescent ; stems and branches short, ascend- 
ing; leaves petiolate, oblong-cuneiform or obversely-lanceolate, narrow, 
with 3 acute teeth or lobes at the apex, 1-3-nerved, coriaceous ; peduncles 
solitary or geminate, with a very short 4-5-flowered, monocarpous 
umbel ; petals villous ; fruit cordate-orbicular, glabrous, shorter than 
the villous, ovate, acuminate, 4-leaved involucre. Thunb. ! Dissert. p. 6.

Root very long and woody. Stem and branches 2-4 inches, tomentose. Leaves 
fasciculate, 2 lines broad, }—1 inch long, attenuated into a short or longish petiole, 
dilated at the base, 3-nerved, the lateral ones often obsolete ; when young tomentose- 
villous, at length nearly glabrous, with 3, rarely 2 teeth at the apex, very rarely 
acute, not toothed. Peduncles 1 line long or shorter. Involucre 3 lines long. 
Pedicels of the sterile flowers glabrous. Fruit sessile, 2 lines long and broad ; 
mericarps with 2 lateral ribs on each side ; furrows flattish, a little rugose. 
15. H. Centella (Cham. & Schlecht. 1. ¢. 37 5); suffruticose, subto- 
mentose or glabrous ; stem and branches terete or subangulate ; leaves 
petiolate, oval, oblong, or lanceolate, acute or acuminate at both ends, 
3-nerved; peduncles fascicled, filiform, with a 3—5-flowered, monocar- 
pous umbel; petals glabrous, rarely subpilose ; fruit obcordate, glabrous 
or pubescent, longer than.the ovate, acute or acuminate, 2-leaved 
involucre.
