Viburnum cassinoides

Viburnum cassinoides most often grows as a dense multi-stemmed shrub with a rounded crown, typically to heights of 5–6 ft (1.5-1.8 m).^[4] Its leaves are simple, opposite, ovate to broadly lanceolate, about 2–4 in (2.5–10 cm) long and have lightly toothed margins.^[5] Moreover, its lateral leaf buds are brown and particularly narrow (technically lanceoloid), whereas its apical flower buds have an inflated base. Both bud types are covered by 2 scales and rest above V-shaped leaf scars that each encompass 3 vascular bundle scars.^[6]

The flowers of Viburnum cassinoides emerge from a dense cluster called a dichasial cyme composed of many trios of one terminal axis and two lateral axes, which may act as terminal axes themselves and develop their own lateral axes. Each axis is terminated by a bisexual flower adorned with 5 white petals, a single pistil and 5 stamens topped with yellow anthers. Additionally, the stamens are perfectly centered on the flower's sepals, which are partially fused at the base.^[6]

Northern wild raisin's flowers develop into fleshy spherical fruits, which are botanically described as drupes and not berries. They gradually change colour from green, to pink, to dark blue, and at maturity their flesh is edible raw or cooked.^[5][6]

Viburnum cassinoides has been recorded under its synonym Viburnum nudum var. cassinoides in Connecticut, Massachusetts, Maine, New Hampshire, Rhode Island and Vermont.^[6] Through iNaturalist, this species has been observed in Ontario, Québec, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland and Labrador (only on Newfoundland Island), as well as northern Michigan, northeastern Ohio, New York State and along the Appalachians down to northeastern Alabama and northern Georgia.^[7]

Although the IUCN has not assessed this species' conservation status,^[8] NatureServe denotes it as Possibly Extirpated in Delaware and Critically Imperiled in Wisconsin and Indiana, where only sparse populations subsist. It is considered Secure across most of the rest of its range.^[1]
