State Rank Reason (see State Rank above)
Parthenocissus vitacea is found scattered in eastern and south-central Montana with a location also documented in Ravalli County. This native vine grows in woody draws and in riparian habitat along streams and adjacent lawns and pastures. Woody draws can be over-used by livestock and in urban areas people may wonder if this plant is invading their lawns. Overall, populations appear to be stable. As an attractive vine that is native to Montana it provides a better landscaping alternative than its introduced relative, Parthenocissus quinquefolia. Current data on locations, population sizes, and threats are needed.

    Range Extent

    ScoreF - 20,000-200,000 sq km (~8,000-80,000 sq mi)

    Comment152,190 square kilometers.

    Area of Occupancy

    ScoreD - 6-25 4-km2 grid cells

    CommentMontana can be divided into 30,390 4x4 square kilometer cells. For this species plant observations occur in 19 of these 4x4 square kilometer cells.

    Number of Populations

    ScoreC - 21 - 80

    Comment22 observations representing discrete locations.

    Environmental Specificity

    ScoreC - Moderate. Generalist or community with some key requirements scarce

    CommentPlants are found in urban and rural areas, but along streams and moist areas which are a more limited habitat in Montana.

    Threats

    ScoreD - Low

    CommentOne observation reported plant as "invading lawns"; however, it is unknown if any land management action occurred. Its habitat of woody draws can be negatively impacted by if overused by livestock.

 
General Description
PLANTS: Woody vines with tendrils. Tendrils are 3- to 5-branched, lack adhesive disks, and are oppositely arranged in the upper leaf axils. Source: Lesica et al. 2012.

LEAVES: Alternately arranged on branches. Leaf blade is palmately divided into 5 leaflets. Leaflets are 5, narrowly obovate in shape, with sparse hairs (glabrate), 3–10 cm long. Source: Lesica et al. 2012.

INFLORESCENCE: A dichotomously branched, hemispheric panicle that arises from the leaf axils. Flowers with reduced sepals and 5 distinct greenish to reddish petals of 2–3 mm long. Berry is 6–10 mm wide. Sources: Lesica et al. 2012; Wen in Flora of North America [FNA] 2016.

Parthenocissus comes from the Greek words Parthenos meaning 'virgin' and kissos meaning 'ivy'.

Phenology
Flowering from may to June and fruiting from August to September (Wen in FNA 2016).

Diagnostic Characteristics
In Montana species of the Grape Family (Vitaceae) can be separated by the degree of lobing in the leaf. Grapes (Vitis) have single leaves with shallow lobes while Woodbines and Virginia Creepers (Parthenocissus) have a single leaf palmately divided into distinct leaflets.

Montana has 2 Parthenocissus species:

Woodbine - Parthenocissus vitacea, native and desireable
*Tendrils: Without an adhesive disc. Look closely where it attaches to a substrate.
*Inflorescence: Panicle is dichotomously branched.

Virginia Creeper - Parthenocissus quinquefolia, exotic
*Tendrils: With an adhesive disc. Look closely where it attaches to a substrate. Discs are easily broken off unless carefully remove.
*Inflorescence: Panicle has a central axis.

Range Comments
British Columbia to Quebec in Canada south to California, Arizona, Utah, Texas, Midwest and eastern U.S., but apparently not in the southeast U.S. (Wen in FNA 2016).

Habitat
In Montana plants grow in riparian forests in the plains (Lesica et al. 2012).

Reproductive Characteristics
Plants reproduce by seed.

FLOWER
Unisexual, perfect, hypogynous, and 5-merous. Sepals are reduced and obscurely lobed. Petals are 5, separate, and 2-3 mm long. Stamens are 5. Pistil has a superior ovary with 1 style.

FRUIT
Fruit is a berry. Berry is round and 2-celled with 2 seeds per cell.
