Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net will point to this new site.
The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.
A familiar genus in cultivation, especially in hedges, the principal taxon being a variety of S. albus. The white fruits in the fall make this species attractive to human eyes and to hungry birds and mammals. Even mature first-year stems can show the distinctly hollow pith characteristic of our common species.
1. Corolla ca. 3–4 mm long; fruit red to purple; pith usually ± uniform (dense or loose but continuous or even absent); flowers in dense axillary clusters of 6–12 or more per node).
1. Corolla ca. (4.5–) 5–9 mm long; fruit white; pith of twigs hollow between the nodes; flowers various.
2. Stamens and style included in the corolla; anthers ca. 1–1.5 mm long; corolla ca. (4.5–) 5–6 (–6.5) mm long; flowers when axillary 1 (–3) per axil (more when terminal as the case sometimes in var. laevigatus).
2. Stamens and style exserted at maturity; anthers 1.7–2.4 mm long; corolla ca. (5–) 6–9 (–11) mm long; flowers mostly 6 or more in axillary (and terminal) spikes.
All species found in Symphoricarpos
