very extremities, and densely clothed with short, cinereous hair. In 
the cultivated state, the branchlets are brown, subangular, pilose, and of 
spreading, dependent habit. Phyllodia copious, alternate, often an inch 
long; in some instances but a little more in length than in breadth, 
elliptical or ovate ; as frequently equilateral as oblique, especially in the 
wild specimens: often of very flexuose surface with undulated, thick- 
ened margins, or almost entirely plane, acuminate, with an attenuated, 
curved mucro; the upper margin more wavy than the lower, and near 
the base furnished with a rather prominent oval gland; smooth, hav- 
ing several faintly-marked primary veins, diverging from the midrib 
at an angle of forty-five degrees, and running parallel to each other. 
Flowers bright-yellow, formed in solitary, rarely geminate capitula, and 
projecting beyond the phyllodia, on peduncles from the axilla, Pedun- 
eles either nearly smooth, or but thinly interspersed with hairs. Calyx 
small, five-toothed, smooth. Corolla five-cleft, each segment erect, 
margins somewhat incurved, apex hooked, Stamens numerous, about 
half the length of the style, Legume (in the ripe state) dark-brown, 
two to three inches long, and one broad, compressed, obtuse, slightly 
curved, subgibbous, the outline often repand or subsinuate, with a 
thickened margin ; smooth, and traversed b parallel, ultimately branch- 
ed veins, one-celled, long-peduncled. Seeds four to eight, seldom more, 
flattish, obtusely elliptical, very smooth, brown-black. Umbilical 
. funicle simple, cymbiform, 
Of the same section as, and closely akin to our plant, our Herbarium 
furnishes several, as yet unpublished species; of which, two more nearly 
allied, have been defined by Mr. CUNNINGHAM, as follows: 
_A. sertiformis ; glaucescens glabra, stipulis acutis persistentibus, phyllo- 
diis obliqué subrotundis perlaté ovatisve acuminatis manifesté parallelo- 
venosis, venulis anastomozantibus, acumine incurvato innocuo, dimidio 
superiore minore ad basin uniglanduloso, capitulis solitariis axillaribus pe- 
dunculatis; pedunculo phylloditin eequante, (nunc duplo longiore,) ramis 
teretibus elongatis incurvatis deflexisve, floribus quinquefidis, petalis sube- 
rectis, stylo staminibus pauld longiore.
