Central lobe deflexed, rounded, with a single shallow notch, 2-2.2mm broad, 1-1.5mm long. Lateral lobes rounded, 1.5mm broad, 1-1.2mm long, spreading. Lower lip single-lobed, lobe 2-2.3mm broad, 1-1.4mm long, reflexed. Lower lip bearded internally and with 2-4 darker pink spots internally. Stamens 4, adnate in the middle of the corolla tube, alternating with the corolla lobes, slightly exserted. Filaments white, pinkish at the apex, terete, glabrous, 2mm long. Anthers pinkish, fading to purple, bilobed, .5-.7mm broad. Style glabrous, 2-2.4mm long, included under the upper lip of the corolla, white, fading to lilac at the apex, terete. Ovary 4-parted, 1mm broad in flower, subtended by a nectariferous ring. The nectary with a basal appendage that protrudes slightly past the top of the ovary.

Habitat - Gravel bars, rich soils, alluvial soils or dry soils along streams, spring branches, gravel bars, roadsides, railroads.
Origin - Native to India.
Other info. - This weedy but showy species can be found mostly in the southern half of Missouri. It is very easy to identify, especially while in flower, as no other plant looks or smells quite like it. The purple stems and distinctive leaves are good characters for identification. The leaves of some plants can be crisped, other may not be. Both types of plants can grow right next to each other and are, at most, phases of the species.
The plant was (is) used traditionally to treat a variety of ailments from diarrhea to morning sickness. It is also used as a culinary herb. This species also produces Perilla oil which is used in food products and also in making lacquers and finishes for wood. Perilla oil is a less expensive substitute for Linseed oil, which comes from another plant, Linum usitatissimum L.

Lower lip to 1.7cm long, with central linear lobe (notched at apex), glabrous internally, pubescent externally. Stamens 2, adnate at apex of corolla tube, exserted from upper lip of corolla. Filaments to 1.4cm long, white, glabrous. Anthers 2mm broad, with brown-purple margin. Style to +3cm long, white below, pinkish-purple at apex, pubescent. Stigma unequally two lobed. Ovary of 4 nutlets. Nutlets to 2mm long in fruit, blackish. Calyx tube to 1cm long, -2mm in diameter, 5-lobed, puberulent, 13-ribbed (nerved). Lobes linear-attenuate, 1.1mm long, dark purple, with spreading cilia on outer margin between lobes and dense erect cilia on margin internally.
Flowering - May - August.
Habitat - Prairies, fields, open rocky woods, glade margins, thickets, roadsides, railroads.
Origin - Native to U.S.
Other info. - This striking species can be found throughout Missouri but is apparently absent in the extreme southeastern section of the state. It is an easy species to ID in the field. The brilliant, dense flower heads and pleasant fragrance make the plant a perennial favorite, literally. The plant is a big favorite among butterfly gardeners and is widely cultivated. It grows easily from seed.
The leaves have been used traditionally as medicine but today are used to flavor teas. The flowers can be used to dress up a salad or garnish a meal.
The species is sometimes broken up into different varieties but these integrate so I won't mention them.

Family - Nyctaginaceae
Stems - To 1m tall, erect to ascending, dichotomously branching, multiple from the base, glabrous or with some minute pubescence at the nodes, often glaucous, 4-angled (the angles rounded), often reddish at the nodes.
Leaves - Opposite, petiolate. Blades truncate to subtruncate at the base, acute at the apex, ovate to lanceolate, typically glabrous but with a few hairs near the petiole, to +10cm long, +7cm broad. Margins with some cilia or a few strigose hairs.
Inflorescence - Terminal cymose clusters of multiple flowers. Pedicels and branches of the cyme with dense antrorse pubescence. Pedicels to +1.5cm long.
Flowering - May - October.
Habitat - Open ground, prairies, waste ground, roadsides, railroads.
Origin - Native to U.S.
Other info. - This showy yet weedy species can be found throughout Missouri. The flowers of this species typically open for about one or two hours per day and then close and drop. The plant is most often seen with closed flowers or, more commonly, in fruit. Despite the short flowering time, this is the most showy species of the genus in Missouri.
Traditionally the plant (root tea) was used to treat fevers and to expel internal parasites. A poultice was applied externally to burns, sores, and swelling. The plant is considered to be toxic and should not be ingested.

Family - Lythraceae
Stems - Multiple from base, becoming woody at the base, herbaceous above, to 2m tall, 4-angled, scabrous, pubescent to hispidulous, erect.
Leaves - Opposite to subopposite in inflorescence, linear-lanceolate to oblong-linear, sessile, somewhat clasping or not, entire, scabrous, +/-10cm long, +/-2cm broad, acute, reduced upward, greatly reduced in inflorescence to foliaceous bracts.
Inflorescence - Dense terminal spikes with clusters of 3-9 flowers per node. Flowers subtended by reduced leaf(foliaceous bract). Bracts dense pubescent. Axis of inflorescence dense pubescent to tomentose.
Flowers - Petals 5, borne at apex of floral tube, to 7mm long, 3.5mm broad, glabrous, subequal, oblong-obovate, pinkish-rose. Stamens 10-12, in two sets of five or six each. Longer set of stamens well exserted. Filaments to 1.3cm long, adnate at base of floral tube. Anthers purple. Shorter set of stamens included to slightly exserted. Filaments white and fading to pinkish-purple at apex. Anthers yellow. Ovary cylindrical-conic, 2.5mm long, 1mm in diameter, glabrous. Style 1mm long, curved. Stigma glandular, capitate, green. Floral tube to 7mm long, 3mm in diameter, cylindric, 12-nerved, dense pubescent, with 6 appendages. Appendages linear-attenuate, 2-3mm long, greenish, alternating with calyx lobes. Calyx lobes pink, to 1mm long, shorter than appendages, acute.
Flowering - June - September.
Habitat - Moist to wet ground along ditches, streambanks, meadows, waste ground, prairies, roadsides, railroads. Also cultivated.
Origin - Native to Europe.
Other info. - Efforts to keep this plant under control in Missouri so far have met with moderate success. The plant is rare in the wild and typically gets destroyed upon its discovery. You can help too. If you find the plant in the wild, report its location to Missouri Department of Conservation. This is no laughing matter as anyone who has been to New England or the Northeast can attest. The plant is highly invasive and can quickly spread through an area and out-compete all native flora. It creates a sea of pink which may be pretty to look at but is an environmental disaster. Don't be tempted to grow it at home, find something else.

Other info. - ...So I'm driving home and I spot a good planting of Delphinium ajacis. I decided to stop and take some snaps. Upon returning to my car I reached for my keys only to discover them still in my ignition and behind locked doors. The passenger window was cracked open a bit so I decided to look for some wire and fish my keys out. As I walked around an abandoned building I found not only some good wire, but also the plant pictured above. The moral of the story? - Always have a spare set of keys handy and ALWAYS have your camera.
