Order XI.—Leguminosa. 
331. Mimosa eburnea L. ? Rob. p. 496. Common in 
the southern parts of Louisiana and Florida ; it 
grows in fields arid sands, forming a large bush, it 
blossoms all the year round, and is at the same 
time covered with flowers and fruits. The bran¬ 
ches are slender, brown, and covered with gemi¬ 
nated straight thorns, one or two inches long, di¬ 
verging and of a shining white ; the flowers are 
yoilow, in a globular head, of the size of a filbert, 
the calyx and corolla are irregular, there are 
many stamina and one style, the pods are round, 
clammy, longer than a finger, with transverse par¬ 
titions and oblong seeds. The M. eburnea being 
a native of the East-Indies, this is probably a dif¬ 
ferent species, to which the name of M. chiona - 
cantha might be given ; but Robin omitting to de¬ 
scribe the leaves, the following imperfect defi¬ 
nition could only be framed, which I have to re¬ 
gret, is not sufficiently comparative. M. chio- 
nacantha Raf. Fruticosa cespitosa aculeata, 
aculeis geminatis stipularis divergentibus patulis 
strictis niveis lucidis, (foliis bipinnatis, foliolis 6 
jugis,) capitulis globosis, floribus irregularis po- 
lyandris, lomentis strictis teretis glutinosis. Raf.
