UMBELLIFERA. 
1. Hydrocotyle Caffra, n. sp.; glabra, foliis peltatis trans- 
verse ovali-orbiculatis, petiolo vix longioribus, 12-nerviis, 
margine circumcirca inciso-lobatis, lobis brevibus latis sub- 
zqualibus obtusiuscule 3-4-dentatis; pedunculis petiolo du- 
plo longioribus umbelle radiis aliis unifloris, aliis longioribus 
umbelluliferis; fructu late orbiculari, vix emarginato, utrin- 
que leviter 3-costato. 
In solo argillaceo-arenoso circa Port Natal (V.c.) Nov. 
1839, legit Dr. Ferd. Krauss, n. 127. 
This species comes very.near H. Bonariensis, Lam. and 
H. petiolaris, DC. (prodr. 4, p. 60), but cannot be united 
with either of them. From both it is easily distinguished by 
its inflorescence, all the flowers being decidedly pedicellate, 
with the longer radii of the umbella are terminated by a 
simple umbellula, instead of bearing one or two distant 
whorls of subsessile flowers. From the latter species it dif- 
fers, besides, in the length of its petioles and peduncles, in 
the form of the leaves (which are even more strongly doubly- 
crenate than in H. Bonariensis), and in the fruit. Moreover, 
there is, at the base of the general umbella, and of the umbel- 
lulz, an involucre of several narrow lanceolate leaflets, nearly 
as long as the pedicels, of which I can find no trace in my 
Brazilian specimens of H. Bonariensis.
