the largest species of the genus; Broker a binata ; Aciphylla Colensoi; 
Celmisia , several sp. ; Colensoa physaloides; Wahleribergia saxicola ; 
Gentiana montuna , and G. pleurogynoides; Calceolaria Sinclairii; 
Ourisia , several sp.; Gallixene parviflora ; Forster a Bidwillii; Helo- 
phyllum Colensoi ; and several of the peculiar orchideous plants, both 
terrestrial and epiphytical. 
30. Lastly, of indigenous Medicinal plants and vegetable substances, a 
few will be here mentioned ;—a future time may prove their value. 
(i.) Those which have already been usefully tried :—the root of the 
Ilarakeke (Phormium tenax,) as an anthelmintic and cathartic ; the 
leaves and bark of the Kohekohe (Dysoxylum spectabile), as a tonic; 
the roots of the Kareao (Ithxpogonim parviflorum ,) as an alterative,— 
this plant is veiy 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 demulcent; the fragrant herb 
Mentha Ctinninghamii, as a diaphoretic; the aromatic leaves of Angelica 
rosccfolia, as a diuretic and remedial in syphilitic cases; and the roots 
of Taraxacum Dens-leonis, as an alterative. 
(ii.) Those which , from their known natural affinities , arc believed to be 
valuable ; from such the following are selected :—the spicy bark of the 
Horopito (I)rimij8 axillaris ,) a species ranking next to the well-known 
T>. JFinteri 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 ( Meltcope ternata ,)—as allied naturally 
to the genus Diosma , species of which genus produce the well-known 
Buchu leaves, which the New Zealand ATelicope also resemblo in taste 
and smell;—the Kawakawa ( Piper exceUum ,)—many closely allied 
species of this gonus (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 spocies are used in medicine, and the roots of P. 
Quinque-folium (a plant closely allied to somo of our 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
