Oval-leaf Huckleberry - Vaccinium ovalifolium
(see State Rank Reason below)
MNPS Threat Rank
State Rank Reason (see State Rank above)
Vaccinium ovalifolium has not been documented in Montana. Past reports have all come from mis-identified specimens. However, the potential for occurrence in Montana exists as northern Idaho supports populations. Potential specimens should be provided to and verified at one of our State Herbaria (University of Montana, Montana State University, or Montana State University-Billings). A conservation status rank is not applicable (SNA) because this plant is not known to occur in Montana.
This excerpt is adapted from the Flora of North America (Vander Kloet in FNA 2009).
PLANTS: Stems clumped, suckering when disturbed, up to 4 m tall; twigs yellow-green or golden brown, glaucous, usually terete, sometimes somewhat angled, glabrous, sometimes hairy in lines.
LEAVES:Leaf blades 25-39 mm long, ovate to elliptic (rarely obovate), pale green or glaucous below, slightly darker pale green above, margins entire to obscurely serrate.
INFLORESCENCE: Calyx lobes vestigial or absent, thin, glaucous and glabrous; corolla 5-7 mm long, globose, sometimes urceolate, and pink, bronze-pink, or greenish white; filaments pilose basally to glabrous. Berries 8-10 mm diameter, blue, dull purplish black, or black, sometimes glaucous.
Oval-leaf Huckleberry - Vaccinium ovalifolium, Not Documented in Montana
Identified by a combination of these characters:
*Habit: Tall shrub that grows in clumps (rarely colonies; suckering when disturbed);
*Twigs: Usually round in diameter;
*Leaves: Mostly without hairs, without glands, and smooth (entire) margins. Mid-vein or top may have some hairs; and
*Berries: Deep purplish, bluish, or black.
Potential specimens should be provided to and verified at one of our State Herbaria:
University of Montana (MONTU), Montana State University (MONT), or Montana State University-Billings (MSUB).
Coniferous woods and adjacent areas, peaty slopes (Vander Kloet in FNA 2009).
