48 NATURAL HISTORY OF PLANTS. 
nists, except Mimosa, Acacia, and Inga ; and even as late as 1783 we 
find Lamarck’ uniting these into a single genus, which he called in 
French Acacie (Acacia), in Latin Mimosa. This was a retrogression, 
for one hundred years since TourneFrort had separated the genera 
Mimosa and Acacia, calling the latter Casse‘ (Cassia). From these 
several small genera, then containing only one or very few species, 
were distinguished towards the end of last century, viz., Adenanthera® 
and Prosopis’ by Linnaus, Hntada’ by Apanson, Zygia® by P. 
Brownu, Gagnebina’® by Necxur, and Neptunia® by Lourziro. A. L. 
DE Jussizv, who knew five of the preceding genera, places them 
without special comment in the Leguminose, with regular corollas. 
In 1814 R. Brown" proposed to make a separate order for Mimosee, 
which De Canpoiie” and Linpixy™ considered only a tribe or sub- 
order of Leguminose, while ExpuicHER,” too, made them an order 
altogether distinct. The most recent authors, such as Benruam & 
Hooker,” retain it merely as a suborder. 
Few of the genera, except those above-mentioned, date more than 
sixty-four years back at the very outside. Tio WILLDENOWw” are due 
two, Schranckia and Desmanthus; to Dn Canpou.E one, Dichro- 
stachys ;" to Von Martius, Pithecolobium, Enterolobium, and Stryph- 
nodendron ;* to R. Brown, Parkia ;° and Affonsea to A. DE Satnt- 
Hivarrz.” Excepting Xerocladia, recently proposed by Harvey,” and 
Archidendron, just characterized by F. Murrizr,” all the other genera 
of Mimosee (viz., Calliandra, Serianthes, Lysiloma, Leucena, Xylia, 
Pentaclethra, Plathymenia, Elephantorrhiza, and Tetrapleura), were 
established between 1842 and 1845 by Bunruam,® who has studied 
this group with no less diligence and success than the rest of the 
enormous Order Leguminosae.
