CONCLUDING EEMAEKS. 
The writer in concluding this small contribution towards the 
literature of industrial plants could not hut feel, that he over- 
stepped already the limits originally assigned to this communi- 
cation. Yet thus far extended as it is, it excludes many important 
genera and species altogether, not merely such as Atalantia, 
Cynodon, Dehregeasia, Villeburnia, Zamia and others, which 
were inadvertently passed, hut 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 Eeport 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
