them both numerically and in the amount of space they occupy. In Antarctic America they are represented 

 by a very few Stellatce, which group is here entirely absent. As no other order exhibits so remarkable an 

 excess, they probably balance the strangely disproportionate want of Composite, which appear to have almost 

 as few representatives in proportion to the mass of exogenous vegetation as any other island. Comparing the 

 dicotyledonous vegetation of the Falkland Islands with that of Lord Auckland's, it will be seen, that in the 

 former the Composite are to the other Dicot. as 1 : 2' 8, and that Rubiacece (Galium) are to Compos, as 1 : 21 : but 

 in the latter group, Compos, are to the other Dicot. only as 1 : 4'5, and Rubiacece to Composite as 1 : 1*6 ! If 

 in each we add these two Nat. Orders together, it will be found, that in the Falklands the proportion which 

 the sum of Rubiacea and Composite bear to other Dicotyledonous plants, is as 1 : 2 - 7, and in Lord Auckland's 

 group as 1 : 2 - 3 : proving, that as far as these two remote localities are comparable, Rubiacete only balance in the 

 latter the want of what is generally, in all climates, the preponderating natural order. This is one only of many 

 equally singular proofs, which a little patient investigation may deduce, that a harmony exists and may be 

 traced in the vegetation of remote climates, whose Floras are otherwise totally dissimilar.

Hab. Lord Auckland's group ; creeping amongst moss in the woods, where its bright red 

 berries give it a pretty appearance. 



My specimens are unfortunately not in flower ; they however entirely resemble the figures of N. depressa 

 above quoted, and agree with numerous Falkland Island and other southern specimens of that plant with which 

 I have compared it. In Mr. Cunningham's ' Flora of New Zealand,' its precise habitat is omitted ; but it is 

 inserted in a MS. copy of that ' Flora' which formed part of my library at sea. There he mentions the " Falls 

 of the Keri-Keri river " as the only locality in which he gathered it. In botanizing over that spot repeatedly 

 in September and October 1841, in company with Mr. Colenso, we often met with Cunningham's plant, both 

 there and afterwards in other moist places near cataracts ; it is however entirely different from the true N. de- 

 pressa, being much smaller in all its parts, with narrower and more acuminated leaves. The berries of the 

 Auckland Island specimens are very much vertically depressed, and their structure is entirely that of the genus 

 Coprosma.
