This species is so different from all others known to m e that I cannot guess at its
affinities. In its large and abundantly white-pubescent flowers (glabrous within except
for the staminal ring), in its large, thin leaves with midvein convex above and
with prominent lateral veins connected by a marginal vein 3-10 m m from the margin
(as in some species of Eugenia), it is apparently unique. The calyx-lobes are thin
in texture and abundantly pubescent on both sides, recalling in this a number of
species of sect Armeriela (e.g., Myrcia tafelbergica, M . calycampa, M . gonini), but
M . speciosa differs from these species in the prominent midvein and in most other
respects. Because the calyx-lobes in the type-collection of M . speciosa are partly
deciduous, I am treating the species as a member of sect Armeriela. It seems to be
known still from the two original collections only.
