Morphology Stem
Stems rigid to sometimes slightly flexuous; bark whitish and striate with brown when young, to dark lead-grey or sometimes purplish-brown, glabrous and smooth to rugose and transversally cracked when older Stems rigid to sometimes slightly flexuous; bark whitish and striate with brown when young, to dark lead-grey or sometimes purplish-brown, glabrous and smooth to rugose and transversally cracked when older.

Morphology Reproductive morphology Flowers

Morphology Reproductive morphology Flowers Pedicel
Pedicels 0.5–5 mm long, covered with minute short glandular hairs
Ecology

Note
