no great demand has up to the present time arisen for it. 

 The Kola-nut plant has been in cultivation in this country 

 for some years previous to 1868, in which year it flowered

Gohibrina reclinata. — The bark of this plant, under the 

 name of Mabee Bark, began to attract some notice in this 

 country as a medicine about 1885, in consequence of its 

 being largely used in the West Indies in the preparation 

 of a stomachic driak. The plant is a native of South

Copernicia cerifera. — This is the Wax Palm or

Diiboisia Hopwoodi. — The broken leaves of this plant, 

 known as Pituki, have been used by the aborigines of

 long journeys or to increase their courage in battle. It 

 was introduced to the notice of the medical world in 1873 

 as a narcotic stimulant. 



JEucalypttis globulus, Blue Gum of Tasmania, where, as 

 .also in Victoria, it grows over 300 feet high. Introduced 

 in 1856, it has become very common in many parts of 

 England, though, with the exception of Cornwall and the
