Porunar aNp Geograpuicat Notice. In so numerousa genus 
as Acacia, it is often very difficult to identify particular species. 
Mr, Bentham has kindly undertaken to compare the present plant 
with those in his own herbarium, and has infaii us that he pos- 
sesses dried specimens of it, collected by Mr. Gunn in Van Dieman’s 
Land, numbered but not named. It evidently belongs to De Can- 
dolle’s third Section, “Spicate; floribus nempe in spicis SHS 
dispositas. Stipule in oteatbul nulle aut minime t 
agrees in general habit and some particulars with A. verticillat, but 
differs considerably from that species in having its leaves scattered, 
and the parts of the perianth less numerous. The leaves are formed 
more like those of oxycedrus, but are probably more succulent. 
INTRODUCTION; WHERE GROWN; CuLtTure. The present specimen 
was raised in the Cambridge Botanic Garden, from seed sent from 
Van Dieman’s Land to the Right Hon. T. Spring Rice, the Chan- 
cellor of the Exchequer, after whom the species has been named, as 
a trifling mark of respect for the ready condescension with which, 
when Secretary to the Colonies, he professed himself anxious to 
further the interes of Botany in any way which his position in the 
t enable him by facilitating the transmission of seeds 
or living Ss from any of our Colonies. The scientific world are 
greatly indebted to him on several occasions, and among others, for 
his application to the Lords of the Treasury for a grant in aid of the 
publication of Mr. Darwin’s work, entitled the “Zoology of the Beagle’s 
Voyage,” and also of Dr. Smith’s work on the New Animals discovered 
by him in South Africa. These two works, in all probability, would 
never have appeared excepting for the liberal and timely assistance 
thus procured for them, and most certainly the public could not have 
purchased them at the reasonable prices at which they are now pub- 
en if they had been undertaken at the personal risk of their 
authors 
From the same packet of seeds from which this plant was raised 
other Acacias have been obtained, but have not yet flowered. They 
have all ae same general aspect, and their leaves are precisely 
similar, but they are labelled, respectively, “Willow-leaved Gum 
Mimosa,” wOséke r Mimosa,” “Broad-leaved Mimosa,” “ Willow- 
e 
leaved Whattle Mimosa.” The present plant may be considered equally 
ornamental with its congeners, and has the advantage over most of 
them in the earlier expansion of its lowers, which appear in March. 
It requires only the ordinary treatment of a sttoreneend plant.
