Loments with 2-4 segments, puberulent, upper margin almost straight across.
Flowering - June - August.
Habitat - Open rocky woods, typically in acidic soils.
Origin - Native to U.S.
Other info. - As I have mentioned before, the species in this genus can be difficult to distinguish from one another. That is not the case with this plant. The peculiar growth pattern of the plant makes it simple ti ID in the field.
Steyermark lists two varieties for the plant. Variety nudiflorum has no leaves present on the flowering stems. Variety foliolatum (Farwell) Fassett has leaves on the flowering stem. Both varities are common throughout most of Missouri except in the northwest 1/4 of the state, where the species is apparently absent.

Involucre - To +3cm tall, 4cm wide, vase-shaped. Phyllaries imbricate, with a spine tip, arachnoid pubescent.
Ray flowers - Absent.
Disk flowers - Corolla pink to rose, tubular, to 3.5cm long. Style 1, exserted beyond corolla. Achenes to 6mm long, 2mm wide. Pappus of plumose bristles.
Flowering - June - September.
Habitat - Pastures, prairies, disturbed sites, waste ground, roadsides, railroads.
Origin - Native to Europe.
Other info. - Many people, including myself, beat up on Carduus nutans as being a horrible exotic pest but Cirsium vulgare cannot be far behind. This is a very common plant. Its spiny leaves and stems are annoying at best. It is a pretty plant but doesn't make a good specimen for cultivation because of its prickles and weedy habit.
The fruits (seeds) are carried great distances by the wind with the aid of their plumose bristles.

Leaves - Main cauline leaves alternate, deeply pinnatifid, (many lobes divided again), to +/-12cm long, +/-7cm broad. Ultimate divisions mucronate, scabrous, entire, oblong. Leaves in upper portions of stem greatly reduced, mostly undivided, scabrous, typically arachnoid pubescent, mucronate, linear to oblong.
Inflorescence - Single flower head terminating stem in a loose paniculiform arrangement of the upper 1/2 of stems.
Involucre - To 1.2cm tall(long), 7-8mm in diameter, ovoid to slightly urcreolate in shape. Phyllaries with prickle tips, imbricate, with some arachnoid pubescence, dark brown to black in upper half, green in lower half. Margins pectinate.
Ray flowers - Absent.
Disk flowers - Outermost flowers enlarged, sterile, 5-lobed. Lobes to 8mm long. Innermost flowers 5-lobed, whitish to pinkish, fertile. Lobes to 4mm long. Anthers pinkish-rose, exserted, connate around style, 2-3mm long. Achenes to 3.5mm long, brown to blackish in fruit, ridged, glabrous to sparse pilose. Pappus of short bristles to 2mm long.
Flowering - June - August.
Habitat - Waste ground, rocky ground, roadsides, railroads.
Origin - Native to Europe.
Other info. - This plant is considered a pest almost every place it grows outside of cultivation. It is most common in the southern and especially the southwestern portions of Missouri.
At first glance the large sterile disk flowers appear to be ligules, but a quick second look will prove otherwise. The plant grows tall and gets very thin and open, much like in the large picture above.

Family - Asteraceae
Stems - To +2m tall, herbaceous, erect, glabrous to arachnoid pubescent, from taproot, often branching, winged(from extended leaf bases). Wings with spiny margins.
Leaves - Basal leaves in a rosette, to +40 cm long, oblong, elliptic, or lanceolate, variously lobed, spiny-margined, glabrous to arachnoid pubescent. Cauline leaves alternate, variously lobed, spiny-margined, sessile with bases decurrent on stem and forming wings, glabrous to arachnoid pubescent.
Inflorescence - Single flower head terminating stem. Head usually nodding, 5-8cm broad.
Involucre - Outer phyllaries spine-tipped, lanceolate, typically recurved, reflexed or spreading, greenish purple, with prominent midvein, to +1.3cm long, +1cm broad at base. Inner phyllaries with weak spine or none, erect to spreading, purple, with prominent midvein. Phyllaries mostly glabrous or with arachnoid pubescence at base.
Ray flowers - Absent.
Disk flowers - Corolla dark pink, to +1.5cm long, 5-lobed. Stamens 5, mostly included. Style exserted well beyond corolla, pinkish to lilac at apex. Achenes glabrous, 4mm long, striped. Pappus of capillary bristles.
Flowering - May - October.
Habitat - Pastures, prairies, waste ground, disturbed sites, roadsides, railroads.
Origin - Native to Europe.
Other info. - This is a very aggressive species which spreads rapidly because of the large number of achenes produced by each plant.
The fruit can travel great distances with the wind because of the large, silky pappus.
The nodding nature of the mature flower heads gives rise to the species name. "nutans" which means "nodding".
This plant can be seen along the sides of virtually every road in the state during the summer.
A plan to eradicate the plant is underway using a beetle, a Curculionid I think, who's larva eats the fruits of the plant before they mature. I have seen the larvae in action and they do inflict some serious damage.
