1 SRS-FIA Invasive Plant Identification 2012-2013 Part 1 This presentation contains the new grass, herb and vine species added to SRS-FIA manual version 6.0.

2 Eragrostis curvula ERCU2 Common names: weeping lovegrass, African lovegrass Densely clumping warm-season grass. Long, thin and wiry basal leaves that arch and droop in all directions almost touching the ground (thus the common name “weeping”). Evergreen or semi-evergreen in the southern Coastal Plain, while dormant whitish, wispy clumps are highly recognizable further north. Still widely seeded for soil stabilization along highways, on surface mines, and around businesses and homes.

3 Eragrostis curvula ERCU2 Common names: weeping lovegrass, African lovegrass Stem not apparent except for the flower/seed stalks. Leaves arise from tightly packed basal sheaths that persist over winter. Leaves thin, less than a quarter of an inch wide, with margins often rolled inward, to several feet long and arching over at mid-leaf to almost touch the ground. Persistent sheaths.

4 Eragrostis curvula ERCU2 Common names: weeping lovegrass, African lovegrass

5 Eragrostis curvula ERCU2 Look-a-likes Resembles no other grasses due to its unique growth habit of tight clumps of “weeping” long and narrow leaves. Eragrostis spectabilis - purple lovegrass Eragrostis curvula - weeping lovegrass

6 Eragrostis curvula ERCU2 Look-a-likes Eragrostis spectabilis - purple lovegrass Eragrostis curvula - weeping lovegrass Arizona Cooperative Extension

7 Liriope muscari LIRIO2 Includes: Ophiopogon muscari, L. spicata Common names: creeping liriope, big blue lilyturf, creeping lilyturf, monkey grass Dense, evergreen ground cover of crowded tufts of grass- like but thicker leaves, 6 to 18 inches tall. Stalked spikes (racemes) of small purple flowers jut upward in early summer. Stalks of small, green-to-black berrylike fruit in summer through winter.

9 Securigera varia SEVA4 Synonym: Coronilla varia Common names: crown vetch, trailing crown vetch Deciduous, perennial forb sprawling to form tangled mats to 3 feet high. Forms brown, “earth hugging” patches in winter that resprout quickly in spring or remain green in southern areas. Caution: All parts are poisonous to some degree. Especially to horses apparently.

10 Securigera varia SEVA4 Synonym: Coronilla varia Common names: crown vetch, trailing crown vetch Alternate leaves, pinnately compound, 2 to 4 inches long, with 2 tiny stipules. Leaflets 11 to 25, dark green, oblong to obovate, with minute hair-like tips. Fruit and seeds May to July and maturing in October. Radiating clusters of slender, pointed seedpods (loments), 2 to 4 inches long, light green maturing to brown.

11 Securigera varia SEVA4 Synonym: Coronilla varia Common names: crown vetch, trailing crown vetch Flowers May to September. 5- 25 small, white to pink, pea-type flowers clustered in clover-like “crowns” about 1 inch wide.

12 Securigera varia SEVA4 Look-a-like Vicia villosa - hairy vetch Tendrils at leaf ends.

13 Securigera varia SEVA4 Synonym: Coronilla varia Common names: crown vetch, trailing crown vetch

14 Ampelopsis brevipedunculata AMBR7 Common names: amur peppervine, porcelain berry Deciduous, woody vine of the grape family, running and climbing over shrub and tree crowns etc. by clinging tendrils, forming thicket and arbor infestations.

15 Ampelopsis brevipedunculata AMBR7 Common names: amur peppervine, porcelain berry Found throughout the region except AR, TX and OK with dense infestations in KY, VA, TN and NC. Alternate, simple leaves, usually 3-lobed sometimes ovate (egg shaped).

16 New leaves smaller and less lobed. Ampelopsis brevipedunculata AMBR7 Common names: amur peppervine, porcelain berry New stems are whitish green, smooth to lightly hairy. Woody vine to 4 inches diameter, climbing by tendrils with forked ends. Tendrils occur on new growth, opposite from leaves. Seedlings

17 Ampelopsis brevipedunculata AMBR7 Common names: amur peppervine, porcelain berry Flowers from June to August. Numerous tiny-branched clusters, opposite from leaves. Fruit and seeds from July to January. Drupes in clusters, whitish, yellow, purple, turquoise, and porcelain blue (thus the common name), with all colors sometimes present. Persist in winter at most leaf axils.

18 AMBR7 Look-a-like Vitis rotundifolia – muscadine Fruits are larger and darker. Leaves usually not lobed. Flower petals meet at tips. Tendrils are not forked.

19 Ampelopsis brevipedunculata AMBR7 Comparison with grapes Ampelopsis sp. Vitis sp. Vitis species stems have a brownish pith. Ampelopsis species have a whitish pith.

20 Akebia quinata AKQU Common names: five-leaf akebia, chocolate vine Woody, deciduous semi-evergreen twining vine to 40 feet long, climbing in tree and shrub crowns and/or forming solid ground cover. Floristic Synthesis of NA © 2010 BONAP

21 Akebia quinata AKQU Common names: five-leaf akebia, chocolate vine Woody, round stem up to 4 inches in diameter. Dark brown/gray with light brown lenticels. Alternate, palmately compound leaves, usually 5 leaflets, 1 to 3 inches long, terminal leaflet usually the largest. Margins entire, tip notched or blunt with tiny hair.

22 Akebia quinata AKQU Common names: five-leaf akebia, chocolate vine Flowers from March to April. Small purple-to-violet flowers of 3 sepals (no true petals). Fragrance likened to chocolate. Fruit and seeds May - October. Light green, turning pink to purplish with lighter speckles and a waxy coating. When ripe the skin splits to reveal a pulpy, edible inner core that splits further to expose many (100+) imbedded black seeds.
