30, Lastly, of indigenous Medicinal plants and vegetable substances, a 
few will be here mentioned ;—a future time may prove their value. 
(1.) Lhose which have already been usefully tried :—the root of the 
Harakeke (Phormium tenazx,) as an anthelmintic and cathartic ; the 
leaves and bark of the Kohekohe (Dysoxylum spectabile), as a tonic; 
the roots of the Kareao (Rhipogonum parviflorum,) as an alterative,— 
this plant is very closely allied to the Sarsaparilla plant (Smilax sarsapa- 
rilla,) and its roots have been beneficially used in New Zealand instead 
of that medicine which is so commonly adulterated (i) ; the bark of the 
Houhere (Hoheria populnea,) as a demuleent; the fragrant herb 
Mentha Cunninghamii, as a diaphoretic ; the aromatic leaves of Angelica 
rosefolia, as a diuretic and remedial in syphilitic cases; and the roots 
ot Taraxacum Dens-leonis, as an alterative. 
(ii.) Those which, from their known natural affinities, are believed to be 
valuable ; from such the following are selected :—the spicy bark of the 
Horopito (Drimys axillaris,) a species ranking next to the well-known 
D. Winteri of Cape Horn, which produces the valuable Winter’s 
Bark ; the intensely bitter bark of the Kowhai (Sophora, or Edwardsia, 
grandiflora, )—it is worthy of notice, that both African and East-Indian 
Kino is produced by plants of an allied genus of the same sub-order ;— 
the leaves of the Wharangi-pirou (Jelicope ternata, )—as allied naturally 
to the genus Diosma, species of which genus produce the well-known 
Buchu leaves, which the New Zealand MMelicope also resemble in taste 
and smell;—the Kawakawa (Piper excelsum,)—many closely allied 
species of this genus (and of the next genus Cubeba,) are extensively 
used as Medicines in various parts of the world ;—the aromatic succu- 
lent stems and roots of various species of Panax, and of Aralia,—of 
which genera several species are used in medicine, and the roots of P. 
Quinque-folium (a plant closely allied to some of owr Panaces,) are sold by 
the Americans to the Chinese for real Ginseng root (P. Ginseng) ;—the 
astringent bark and diuretic seeds of Sapota costata ;—the roots of the 
2 Mountain Gentians, which are just as purely bitter as those of the 
officinal Gentiana lutea ;—the aromatic bark of the Tawa (Nesodaphne
