Description:
Description - Leaf rachis without an obvious wing, at most narrowly marginate; leaflet apex mostly acute or bluntly acute, sometimes rounded; axis of the inflorescence velutinous, sometimes with some longer hairs intermixed, the buds densely tomentulose; filaments of the 2-4 larger stamens densely villose, the pollen of all the stamens globose or subglobose, 26-31 µ diameter; gynoecium always unipistillate, villose-sericeous, the hairs loose and not appressed; fruit 4-6 cm long and 3 cm wide, smooth at maturity but obliquely transverse-costulate earlier.

Discussion:
Vogel’s S. montana is certainly conspecific with this variety and the rather crude drawing of Mimosa pacoba in the Vellozo publication is surely referable here, too.The typical variety of S. flaemingii (Fig. 16g-i) differs from the other varieties in its wingless and emarginate leaf-rachis and the densely pubescent filaments of the larger stamens. Var. arumateuana (Fig. 16a-c) is quite distinct from the other two varieties in the large number of larger stamens and in the leaflets being glabrous on the upper surface; in the larger-stamen number, this variety is similar toS. macrostachya var. kuhlmannii but the leaflets are more like those of S. flaemingii. Harms’ species, S. psilonema, has been reduced to varietal rank in this treatment to emphasize the very close relationship that appears to exist between these taxa. In addition to the slight, not completely constant differences of leaflet shape and filament vestiture, war. psilonema (Fig. 16d-f) is well separated geographically.There is the closest possible relationship between this species and S. macrostachya, although they differ superficially to a remarkable extent, considering what must be interpreted as close evolutionary affinity. The leaflets of this species are predominantly oblong or oblongish and are considerably smaller than the distinctly ovate or elliptic ones of S. macrostachya; in addition, there are usually fewer pairs of leaflets per leaf in the latter species, although there is overlapping in this characteristic. The two varieties of S. acutifolia with pubescent gynoecia differ in leaflet shape and pubescent type.
