sericeous

It is sericeous (silky) throughout, giving the stem a silvery-grey appearance.

Terminal buds are broadly ovoid or globular, and covered with sericeous scales.

Leaf texture is sericeous adaxally (above) and abaxally (below), giving the leaves a silvery-grey appearance.

The branchlets are moderately to densely sericeous on emergence but becoming sparsely so to nearly glabrous.

The Symphyotrichum sericeum plant is distinctive in the wild due to the silky texture; no other American aster is sericeous throughout.

Unlike in Trochetia, the Trochetiopsis flowers have only five stamens, and the sepals generally have appressed sericeous indumentum on their interior faces (although one species, T. melanoxylon, lacks this last character).
