A. Farnesiana, 1 a species often cultivated in the south of Europe, 

 has been made by some authors the type of a genus apart, 2 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 pub) 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. lojjhanta? a species also cultivated in our conservatories, has 

 become the type of a separate genus, under the name of Albizzia* 

 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 A. 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. (J acq., op. cit., 

 t. 396.— Velloz., loc. cit., t. 2S, 29, 36-38.—

 (Prod i"., ii. 464, n. 159), whose fruit separates 

 into one-seeded joints, and which Hasskael 

 has made the type of the genus Arthrosporion 

 (Betzia., i. 112). Besenna anthelmiidica A. 

 Rich. (Fl. Abyss., i. 253), attributed to this 

 by Beniham (Gen., 595), certainly belongs to 

 the group Albizzia. 



VI. FilicincB. — Woody or rarely herbaceous 

 unarmed plants; leaves bipinnate without pe- 

 tiolar glands. Capitula globular or elongated, 

 axillary fasicled flowers sometimes shortly pedi- 

 cellate. Species about ten, from North or Cen- 

 tral America. (Jacq., Eulug. Amer., t. 78. — 

 K., op. cit., t. 31.)

 — A. lenticellata F. MUEIL., in Journ. Linn. 

 Soc, iii. 147. — Mimosa Famesiana L., A'/'"'., 

 1506.— M. scorpioides Foksk. 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 arc 

 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. Bentiiam refers 

 this species to the section Gummifera. It is 

 true that its fruit is nearly cylindrical or slightlv 

 torulose; and the pericarp forms oblique septa 

 between the seeds marking out one-seeded com- 

 partments arranged alternately in two rows. 

 But A. iortuosa W. (Spec, iv. 1083 ; — DC, 

 Prodr., n. 132), and some other species of the 

 section Gummiferce have already a thickened pod 

 with the seeds contained in incomplete cells, and 

 thus affording a transition towards A. Farne- 

 siana.
