Description:Distribution and Ecology - Trees to 2 meters insavanna-like forest between Serra Pirapucu andRio Maturaca (ca. 0°40'N, 66°08'W0 Amazonas,Brazil (Fig. 2), this being the first report of thespecies in Brazil. K n o w n only from the type collection,which was in bud in January and was made at 600 m elevation. This locality is immediatelysoutheast of Serra da Neblina and onlya few kilometers from the Venezuelan border.Thus, var. densesericea should also be expectedto occur in Venezuela.

The collection upon which this variety is based
is in bud only, but nevertheless is readily referable
to J. memorabilis. The typical variety has
leaves that are puberulent and obviously glandular
below. The major veins of the leaves of
var. memorabilis are sometimes sericeous below
and the leaf undersurfaces are pale green. This
is in contrast to the leaves of var. densesericea,
which are very densely and evenly sericeous below,
these hairs thereby completely obscuring the
midrib and any glands that may occur in the
areoles. The dense silky pubescence persists on
mature leaves and imparts a golden or bronze
color to the leaf undersurfaces.
