LEGUMINOS-MIMOSEZ. 41 
A. Farnesiana, a species often cultivated in the south of Europe, 
has been made by some authors the type of a genus apart,” on account 
of the structure of its fruit, which is irregularly cylindrical, some- 
what curved, and as thick as it is broad; it is filled by a pulp which 
dries up and isolates the seeds, arranged obliquely in two rows, as if 
in complete or incomplete cells. Botanists are now agreed in making 
it only a section of the genus Acacia, of which that plant has the 
habit, the foliage, and very nearly the flower. 
A. lophanta; a species also cultivated in our conservatories, has 
become the type of a separate genus, under the name of Aldizzia,' 
because its stamens are monadelphous, instead of being quite free, 
as is the case in many Acacias. But all the other characters being 
identical in both types, neither fruit, flower, nor vegetating organs 
presenting any marked differences, we are,absolutely compelled to 
leave 4. lophanta in the genus Acacia, where we have already seen 
species with their staminal filaments united for some short distance. 
Thus, too, it seems impossible to us to make a separate genus for 
vinera of the bipinnate leaves which have glan- 
dular petioles and non-spinescent stipules, 
Flowers in capitula or spikes fascicled axillary, 
or collected into racemes at the end of the 
branches. Species about sixty. (Jacq., op. cit., 
t. 396.—VELLoz., loc. cit., t. 28, 29, 36-38.—

Pl. Natal., t. 1.—Harv. & Sonp., op. cit., 
282.) To this group belongs A. concinna DC. 
(Prodr., ii. 464, n. 159), whose fruit separates 
into one-seeded joints, and which HassxaRu 
has made the type of the genus Arthrosporion 
(Retzia., i. 112). Besenna anthelmintica A. 
Rica. (Fl. Abyss., i. 253), attributed to this 
by Bzentuam (Gen., 595), certainly belongs to 
the group Albizzia. 
VI. Filicine.—Woody or rarely herbaceous 
unarmed plants; leaves bipinnate without pe- 
tiolar glands. Cupitula globular or elongated, 
axillary fasicled flowers sometimes shortly pedi- 
cellate. Species about ten, from North or Cen- 
tral America. (Jacg., Helog. Amer., t. 78.— 
K., op. cit., t. 31.)

Soc., iii. 147.—Mimosa Farnesiana I.., Spee., 
1506.— UL. scorpivides Forsk. The corolla of 
this species is gamopetalous and valvate or very 
slightly imbricate near the apex in the young 
bud. The stamens are free for the greater part 
of their length; but towards the base they co- 
here into one or several bundles, and are inserted 
on the base of the corolla. The ovules are 
numerous, and at first arranged in two vertical 
rows, with their raphes facing. Later on they 
appear to form a single row. The style is 
slightly dilated at the apex. BEnTHam refers 
this species to the section Gummifere. It is 
true that its fruit is nearly cylindrical or slightly 
torulose; and the pericarp forms oblique septa 
between the seeds marking out one-seeded com- 
partments arranged alternately in two rows. 
But A. tortuosa W. (Spec., iv. 1083 ;— DC., 
Prodr., n. 132), and some other species of the 
section Gummifere have already a thickened pod 
with the seeds contained in incomplete cells, and 
thus affording a transition towards 4. Farne- 
siana.
