CONCLUDING REMARKS. 



THE writer in concluding this small contribution towards the 

 literature of industrial plants could not but feel, that he over- 

 stepped already the limits originally assigned to this communi- 

 cation. Tet thus far extended as it is, it excludes many important 

 genera and species altogether, not merely such as Atalantia, 

 Cynodon, Debregeasia, Villeburnia, Zamia and others, which 

 were inadvertently passed, but also numerous others of perhaps 

 secondary note, yet sufficiently significant to be reserved for a 

 supplemental treatise. Nevertheless to about seven hundred 

 prominent utilitarian plants now primary local attention has been 

 directed in a connected form, which with the three hundred 

 timber-trees, enumerated in* last year's Report of the Acclima- 

 tisation Society, gives us a list of about one thousand plants for 

 our cultural choice. But besides indirectly or passingly the 

 writer has alluded to very many more ; and these indications 

 ought to aid many of our colonists to trace out still further novel 

 resources for their requirements in husbandry or technology or 

 any other purpose. It is the intention at an early opportunity 

 to add to these lists, and to group also the products of the various 

 timber- trees together in an augmented index, as many of these 

 furnish also medicinal substances, dyes, oils, gums, resins, esculent 

 fruits and other articles of our wants. Thus notes for instance 

 on Camphor, vegetable tallow, real manna, maple-sugar, hickory- 

 nuts, sandarac, turpentine, kauri, &c., must be sought among 

 the timber-trees. Simultaneously then a geographic grouping 

 of all these indicated plants will be effected, in order that at a 

 glance may be indicated, what from each particular country in 

 various parts of the globe may be secured. The range of each 

 recorded species is now already given with a view of affording a 

 clearer insight into the adaptability of different climatic tracts 

 and altitudes of this colony or countries within the same 

 isothermal lines for special plants. Furthermore to give to
