GENUS INDEX

GENUS CODE: VIBUR
GENUS SCIENTIFIC: Viburnum
GENUS AUTHORITY: L.
GENUS COMMON: Viburnum
GENUS SUMMARY: (contributed by B.A. Sorrie & A.S. Weakley)
GENUS IDENTIFICATION: Identification notes: Leaves vary in shape in some taxa more than in others; we have allowed for some of this variation in the key, but readers should expect that some specimens will not key cleanly, especially rapidly-growing vegetative shoots. Petiole length of leaves varies considerably, even with those possessing �short� petioles. However, by measuring only the petioles of the first leaves below an inflorescence one reduces the chances of misidentifications greatly. Warning: even in some of the �long� petioled taxa, one may occasionally encounter unusually short petioles; therefore it is wise to examine several twigs. Density of pubescence and glandularity of leaves, petioles, and inflorescences varies more in some taxa than in others; we have allowed for some of this variation in the key, but readers should expect that some specimens will not key cleanly, especially vegetative shoots. Stipitate glands are usually very short, especially those on leaf veins; a 10� lens may not be adequate to see them clearly. It is our belief, based on thousands of specimens examined and years of fieldwork, that most Viburnum tend to lose pubescence, and perhaps glandularity as well, as the season progresses.

FAMILY INDEX

FAMILY CODE: VIBURN
FAMILY SCIENTIFIC: Viburnaceae
FAMILY AUTHORITY: Rafinesque 1820
FAMILY COMMON: Viburnum Family
FAMILY SUMMARY: A family of about 5 genera and about 175-210 species, shrubs, small trees, and herbs (here interpreted as including Sambucus and Viburnum), mainly of the Northern Hemisphere. There now appears to be little doubt that Sambucus and Viburnum are more naturally placed in a separate family, in contrast to their traditional placement in the Caprifoliaceae (Zhang et al. 2003, Eriksson & Donoghue 1997). The correct name for that segregate family has been in dispute, but the failure of a super-conservation proposal for Adoxaceae means that Viburnaceae is the correct name (Wilson 2016).
