The largest New Zealand species, and one universally distributed throughout the Tropics of both hemispheres, 
the temperate latitudes of North and South America, the Cape of Good Hope, Australia, and Tasmania. It is 
perhaps the most distinct species of the genus, easily known by its robust habit ; its leaves fasciculate at the root- 
ing knots of the creeping stem, on petioles 1-7 inches long, with the lamina cordate, with a shallow sinus at the 
base, blunt, sinuated or entire ; its short peduncles; conspicuous involucre ; and large, broad-ribbed carpels. 
4. Hydrocotyle tripartita, Br.?; glabra, caule breviusculo, foliis parvis palmatim 3-partitis, seg- 
mentis cuneatis 2-3-fidis, pedunculis folio subzquilongis, umbella capitata 3-5-flora, carpellis pallidis 
utrinque l-costatis. DC. Prodr. v. 4. p. 65 (non Hook. Ic. Plant. t. 312). 
Haz. Northern Island. Swamps at the foot of Tongariro, Colenso. 
I am in doubt whether this be the plant of Mr. Brown or not; it is certainly not that figured and described by 
me as such in the “Icones Plantarum. My New Zealand specimens are very insufficient —Whole plant an inch 
or so long, rather stout, smooth. Leaves divided to the base into three cuneate segments, + inch long, lobed. 
Peduncles nearly as long as the petioles. Umbels few-flowered. Carpels pale, sessile, with one rib on each face. — 
This much resembles starved specimens of Ranunculus acaulis. 
5. Hydrocotyle Nove-Zelandie, DC.; pilosa v. glabrata, caule elongato hirto tenello petiolis pe- 
dunculisque superne preecipue retrorsum hirsutis, stipulis latis membranaceis persistentibus, foliis reniformi- 
rotundatis sub-7-lobis acute dentatis v. obtuse crenatis glabratis, pedunculis petiolo brevioribus zqui- 
longisve, umbellis laxe 5-10-floris, carpellis pallidis utrinque obsolete 1-costatis. DC. Prodr. v. 4. p. 67. 
H. dichondreefolia e? H. Novæ-Zelandiæ, 4. Cunn. Prodr. H. pilosa, Banks et Sol. MSS. et Ic. 
Has. Very abundant throughout the Islands, Banks and Solander, etc. 
A very common and variable plant, nearly allied, if not identical, with a Chilian species (7. Bonplandii ?). 
Stems 1—10 inches long, more or less hairy, especially on the peduncle and petiole, where the hairs are reversed; 
also variable in the depth of lobing and sharpness of the teeth or crenatures, and of the depth of the sinus of the 
leaf. Dr. Lyall’s specimens from Bluff Island have a prostrate almost woody stem, but the stems are usually weak 
and trailing, and, as well as the whole plant, pale yellow-green. Stipules conspicuous, membranous. Leaves 
4-1 inch broad, orbicular-reniform. Peduncles shorter than or as long as the leaves. Umbels loosely five- to ten- 
flowered.  Carpels pale, with one often obscure rib on each face.—I have imperfect small specimens apparently of 
this plant, with leaves three- to five-lobed to the middle. 
6. Hydrocotyle moschata, Forst. ; hispido-pilosa, pusilla, caule (pro planta) robusto repente, foliis late 
reniformi-rotundatis 5-7-lobis, lobis argute dentatis, pedunculis folio brevioribus, capitulis multifloris, 
fructibus dense compactis parvis brunneis, carpellis utrinque costatis dorso acutis. Forst. Prodr. DC. 
Prodr. v. 4. p. 67. A. Rich. et A. Cunn., ete. 
Var. B. compacta; folis profundius lobatis, lobis inciso-dentatis, pedunculis brevibus. H. compacta, 
DC. Prodr. A. Rich. A. Cunn. H. capitata, Banks et Sol. MSS. et Ic. 
Has. Both varieties abundant throughout the Islands, Banks and Solander. Forster, ete. 
This common little plant is, I think, identical with a Chilian one ; it resembles in habit and foliage small robust 
hairy specimens of H. Nove-Zelandie, from which it differs in the much smaller crowded dark brown fruits, the 
carpels of which have sharper ribs and are sharp at the back. Though generally very distinct, I have many 
specimens which might belong to either. Stems much branched, 1-3 inches long. Stipules membranous, con-
