Flowering - May - August.
Habitat - Streambanks, muddy shores, ditches, moist ground.
Origin - Native to U.S. and Eurasia.
Other info. - This is one of the first plants I photographed in this state. The plant is a fast growing annual which produces a multitude of small yellow flowers. The fruits are quite large for the size of the flowers and make the plant easy to identify.
Our plant belong to variety sceleratus f. sceleratus. There is another form which is aquatic and not yet found in this state. This is form natans Gluck.
This species can be found along the Missouri, Mississippi, and a few other rivers.
The plant is somewhat toxic and can cause skin irritation to people allergic to it.

I NEED HELP WITH MY KALANCHOE PLANT PLEASE! I bought this little guy a few months ago and it bloomed for my a few days after i bought it. It was fine until l 3 weeks later when i noticed the leaves shriveling up. It continued to lose it leaves and I pruned the flowers so it can focus all its energy on regaining its health. During the past few months I've repoted the plant, checking for root rot or any pest and i found nothing. Ive changed waterings, light, anything you can think off and it continues to loose it leaves. If you guys can help me save this plant, please comment any suggestions!

Family - Hippocastanaceae
Stems - Woody to 9m tall, with a single trunk or multiple trunks.
Leaves - Opposite, palmately compound, petiolate. Leaflets typically 5, but sometimes 6 or 7, 3-8cm wide, 15cm long, serrate, pubescent below, glabrous above, acuminate. Petiolules to 1cm long.
Inflorescence - Terminal panicle to 20cm long on new season growth. Axis of inflorescence densely pubescent with multicellular hairs. Pedicels pubescent, to 8mm long in flower.
Flowers - Petals 4, pale yellow to creamy whitish, clawed. Claws of upper petals to 3.5mm long, with dense tuft of villous pubescence at apex. Limb of upper petals +1.5cm long, 4mm broad at apex, with reddish spot near base of limb, pubescent. Lower petals with claw to 3.5mm long. Limb of lower petals +1cm long, 8-9mm broad, pubescent. Stamens 7, exserted. Filaments villous, to -2cm long, white. Anthers orange-red, 2mm long. Ovary 6mm long, dense villous at base but glabrous and reddish at apex. Calyx tube to 7mm long, 5mm in diameter, 5-lobed, yellow-green, pubescent. Lobes to 3mm long, obtuse, pubescent. Fruits globose, spiny, 2.5-6cm in diameter. Seeds 2 per fruit, +/-3cm in diameter, shiny, dark brown.
Flowering - April - May.
Habitat - Wooded slopes, ravines, thickets, open, rich woods, also cultivated.
Origin - Native to U.S.
Other info. - This species can be found throughout Missouri but is apparently absent from the extreme southeastern and northwestern corners of the state. The tree is easy to identify because of its palmately divided leaves (which are opposite) and its big inflorescences. The buds are easy to ID in winter also as they are quite large and the tree generally has a widely spreading growth habit. This species deserves to be cultivated more and it grows easily from seed. The fruits of the plant split into 3 parts and the seeds are actually edible. The seeds should be cooked first as they can be mildly toxic if eaten raw.

Flowers - Petals 3, purple to pinkish-red, broadly ovate, to 2cm long and broad, glabrous, spreading. Stamens 6, erect. Filaments +/-6mm long, purple, glabrous in the apical 1/2, densely pubescent with long, purple, multicellular hairs in the basal 1/2. Anthers yellow, 2-lobed, +2.5mm broad. Ovary light green, glabrous, 2mm long, +/-1.3mm broad. Style +3mm long, glabrous, purplish. Sepals 3, to 1.5cm long, +/-7mm broad, elliptic, entire, slightly inflated, acute, densely pubescent externally, glabrous internally, distinct.
Flowering - April - June.
Habitat - Mesic to dry upland forests, shaded ledges of bluffs, open rocky woods, glade edges, railroads.
Origin - Native to U.S.
Other info. - This striking species can be found mainly in the eastern half of Missouri in counties that border the Missouri and Mississippi rivers. The plant can be identified by its small size, pubescent sepals, and narrow leaves. This species seems to prefer acidic soils but would do well in cultivation and makes an attractive garden specimen.
Stems - Single or multiple from the base, from thickened roots, to 30cm tall, erect, herbaceous, glabrous basally, puberulent at the apex, slightly zig-zag. Hairs of the stem with thickened pustulate bases, multicellular (of 2-3 cells).
Leaves - Alternate, sessile, sheathing at the base, with the blades narrower than their flattened and unfolded sheaths. Sheaths glabrous, with long pilose hairs on the margins. Leaf blades linear, grass-like, sparsely hairy, with long cilia on the margins basally, to +30cm long, to +/-1.5cm broad, entire, green above, silvery-green below with parallel venation.

Family - Liliaceae
Stems - Aerial stems to +15cm tall, erect, green, glabrous, angled, purplish near apex, from small bulb. Bulb +/-1cm in diameter, with fibrous roots.
Leaves - Basal, typically 2-3 per plant, folded longitudinally at base, entire, linear to narrowly oblong, to +/-20cm long, 1.5cm broad.
Inflorescence - Few flowered raceme terminating the aerial stem, sometimes just single-flowered. Pedicels purple, 6-9mm long, glabrous, subtended by small scales. Scales light purple, succulent, to 1.5mm long.
Flowers - Tepals 6, 1.5-1.7cm long, 5-6mm broad, blue, glabrous, oblong to narrowly ovate, entire, with a single blue midvein. Stamens 6, adnate to the base of the tepals. Filaments white, erect, 8mm long, glabrous, compressed at base. Anthers blue, 2.1mm long. Style 6mm long, purple, glabrous. Ovary green, superior, 4mm long, 3-angled, 3-locular. Placentation axile. Seeds (ovules) many.
Flowering - March - April.
Habitat - Mesic bottoms, moist slopes, roadsides, fields.
Origin - Native to Russia.
Other info. - This attractive little garden species has escaped to a few counties in Missouri but is widely cultivated. Where escaped it can be quite aggressive and locally abundant.
The typical flower color is blue but colors vary depending on the cultivar. So far, only the blue flowered plants are found wild in Missouri. Like most plants in the genus, this species is toxic.

Family - Passifloraceae
Stems - Vinning, glabrous to minutely pubescent, herbaceous. Tendrils present.
Leaves - Alternate, 3-lobed, serrulate, petiolate, to +15cm long, +13cm wide, glabrous. Petioles with two glands near base of leaf blade.
Inflorescence - Single pedicillate flowers from leaf axils.
Flowers - Very interesting. This flower exhibits a corona which is a structure of appendages situated between the corolla and stamens. In the picture the corona is the ringlike structure of purple and white appendages above the petals and sepals. Flower is typically 6-7cm broad. Petals 5, sepals 5, purplish to whitish, similar, alternating. Styles 3. Stamens typically 5. Sepals 5, greenish-white, with a terminal appendage.
Fruit - Fleshy, ovoid to globose, green at first, yellowish-red at maturity.
Flowering - June - September.
Habitat - Thickets, disturbed sites, waste ground, roadsides, railroads. Also cultivated.
Origin - Native to U.S.
Other info. - This plant and its relatives have an edible fruit often seen in drinks as "Passion fruit". Some folks like it, some don't. In his particular species the mucilage around the seeds of the fruit is quite sweet and delicious.
The genus name comes from the story of Jesus in Christianity, the "Passion". The flower parts are telling of the story. The petals and sepals are representative of the disciples of Jesus, except for Judas and Peter. The stamens, numbering 5, represent the wounds of Jesus. The stigmas, because of their shape, represent the nails used in the crucifixion. The corona represents the crown of thorns.
