Leaves - Opposite, decussate, sessile, linear to linear-spatulate, to 1.5cm long, 3mm broad, entire, glabrous, rounded to subacute at the apex, densely glandular punctate on both surfaces.
Inflorescence - Single axillary flowers. Pedicels to +/-5mm long, glabrous.
Flowers - Corolla purplish (very rarely all white), bilabiate, 1.2cm long, pubescent externally, contracted and brown at the base in the calyx-covered portion. Upper lip single-lobed. The lobe deflexed, 3-4mm broad, 2-3mm long, emarginate. Lower lip 3-lobed. Lobes rounded, 2mm long and broad. The center lobe slightly larger than the laterals. Stamens 4, didynamous, 2 attached in the basal 1/4 of the corolla tube, 2 attached in the apical 1/4 of the corolla tube and slightly exserted. Filaments whitish and glabrous, to +3mm long. Anthers lilac, bilobed, 1mm long. Style white (lilac at the apex), glabrous, to 1cm long. Stigma unequally 2-lobed. Ovary green, glabrous, deeply 4-parted, .5mm long. Calyx bilabiate. Calyx tube to 4mm long, glandular punctate, with 13 ribs, greenish-purple. Upper lip 3-lobed. Lobes acuminate, 1.1-1.2mm long. Lower lip 2-lobed, lobes equal or slightly longer than upper lobes, acuminate. Calyx with a ring of floccose hairs at the summit of the tube internally.
Flowering - May - October.
Habitat - Limestone glades and knobs, rocky open ground, wet meadows along spring branches, gravel bars, bluffs escarpments.
Origin - Native to U.S.
Other info. - This little species is very common in the Ozarks of Missouri. The plant is more often smelled than seen. Plant hunters strolling through the glades of Missouri often step on the plant releasing a very strong mint flavor into the air. The smell is unmistakable. Because the plant has thin stems and thin leaves it often gets overlooked until that smell fills the air. Chewing on the plant gives you fresh breath that will last for hours.

Leaves - Cauline leaves opposite, linear to lanceolate or oblong(or combinations of the three), sessile or short petiolate, to +8cm long, 2cm wide, variously pubescent, serrate to denticulate or entire, typically well over 20 in number on the stem.
Inflorescence - Terminal spikes of whorled flowers (verticillasters). Typically 1-4 flowers per node. Flowers on pedicels to 6mm long, recurved pubescent. Each cluster typically subtended by a reduced foliaceous bract.
Flowers - Corolla blue, strongly bilabiate, to 2.5cm long, pubescent externally. Lower lip much larger than upper lip, to +1cm broad, 3-lobed. Central lobe notched at apex. Lateral lobes much smaller than central lobe. Upper lip galeate, entire, to 1cm long. Stamens 2, covered by upper lip. Calyx bilabiate, with 12-13 ridges(nerves), to 1cm long, pubescent. Upper lip to +2mm long, acute. Lower lip slightly smaller to equaling upper lip. Ovary of 4 nutlets. Nutlets to -3mm long, brown and glabrous when mature.
Flowering - July - September.
Habitat - Prairies, glades, bluffs, disturbed sites, roadsides, railroads.
Origin - Native to U.S.
Other info. - This striking species can be found growing wild mainly in the southwestern corner of Missouri. It is cultivated elsewhere.
According to Steyermark, the typical variety found is var. grandiflora Benth. which has recurving pubescence on the stem. This plant is pictured above. Another variety, var. azurea has a pubescence which is more straight, spreading or ascending. This latter variety is less common.
The seeds of this plant, like all the mints, are small nutlets which can be found inside and at the base of the calyx. I mention this because I have observed people digging the plant to take home and grow. If you want to grow the plant, COLLECT THE SEEDS!!

Expanded portion of corolla tube to +1cm long, 1cm in diameter, pubescent. Corolla lobes +/-1.5cm long and broad, glabrous internally, pubescent externally with some glandular pubescence near the base. Stamens 4, didynamous, adnate at the apex of the constricted portion of the corolla tube. Filaments white, 1.3cm long, sparse pubescent at the base, glabrous above. Anthers yellow, 3mm long. Style -4cm long, sparse pubescent below, white. Stigma 2-lobed, curled. Ovary superior, with some glandular pubescence at apex near style, 4mm long, 1.3mm in diameter, conic, 2-locular. Calyx tube to 5mm long, 5-lobed. Lobes linear-lanceolate, 2-3cm long, 3mm broad, with long and short glandular pubescence, entire, erect. Capsules brown, glabrous, to 2cm long, explosively dehiscing.
Flowering - May - October.
Habitat - Waste ground, disturbed sites, moist, open woods, streambanks.
Origin - Native to U.S.
Other info. - Although the corolla looks regular, it is typically zygomorphic, with one petal being slightly larger than the other four. The flowers of this species only last for one day but the plant produces many flowers while in bloom. This species is common and reminds many people of the non-related "Petunia" of cultivation.
Steyermark lists three forms for the plant based on flower color and size. Form strepens is shown above. Form alba Steyermark has a white corolla. Form cleistantha (Gray) McCoy has cleistogamous flowers but may not be a distinct form, rather a phase of form strepens.

Leaves - Opposite, petiolate. Petioles +3c, long at base of plant, reduced above, villous, winged on upper leaves. Blades lance-ovate below, lanceolate above, to +/-6cm long, =2cm broad, entire or with a few shallow teeth, somewhat undulate, strigose.
Inflorescence - Terminal dense 4-angled spike of verticillasters to +/-7cm tall(long), 1.5-2cm thick. Verticillasters each with 6 flowers(3 flowers per cymule). Cymules subtended by broad ciliate-margined bracts. Bracts decussate, abruptly acuminate, 1.6cm broad. Flowers sessile.
Flowers - Corolla bilabiate whitish-purple. Corolla tube to 8mm long, glabrous. Upper lip galeate, purple, 6-7mm long, 5mm broad, with a few villous hairs externally on midvein. Lower lip 3-lobed. Lateral lobes 2-3mm long, 1.5mm broad. Central lobe 4mm long, deflexed, fimbriate-erose at apex, light purple. Stamens 4, didynamous, included under the galea, upper pair adnate near base of galea, lower pair adnate near base of corolla tube. Filaments purple, glabrous, the longest to 1.2cm. Anthers purplish-brown. Style inserted between upper pair of stamens, glabrous, lilac, 1.6cm long. Stigma 2-lobed. Ovary 4-parted. Calyx bilabiate, accrescent, 10-nerved. Tube to 5mm long in flower. Upper lip with three mucronate lobes, reddish-purple at apex. Lower lip 2-lobed. Lobes acuminate, 3mm long in flower, reddish-purple. Calyx villous on margins and on nerves. Nutlets to 2mm long, brownish-yellow, glabrous.
Flowering - May - September.
Habitat - Waste ground, disturbed sites, open woods, pastures, roadsides, railroads.
Origin - Native to Europe, Asia, and North America.
Other info. - This is a very common species in this state. The plant is generally quite small and can bloom at just a few cm in height if it is growing in an area where it gets frequently cut or mowed. The species designation means "common" and is frequently used in botanical nomenclature to describe plants that are indeed common.
Steyermark busts the species apart into different varieties and forms. I won't go into those here but it is worth noting that our plants belong to variety lanceolata (Bart.) Fern. and the European plants belong to variety vulgaris. Both varieties can be found in Missouri but var. lanceolata is much more common.

Family - Polemoniaceae
Stems - To +40cm tall, herbaceous, erect, typically simple below but branching at inflorescence, single or multiple from base, from taproot, simple to glandular pubescent.
Leaves - Opposite(maybe a few alternate bracts in inflorescence), sessile, linear to linear-lanceolate or ovate, entire, acute to attenuate, rounded at base, to +/-5cm long, +/-1cm broad, pilose to glandular pubescent, with single prominent midrib.
Inflorescence - Terminal and axillary cymes, many flowered (+/-50). Peduncles and pedicels densely glandular pubescent. Pedicels to +/-9mm long. Flowers often subtended by linear-lanceolate bracts.
Flowers - Corolla various shades of purple or rarely white, 5-lobed. Corolla tube to 1.5cm long, 2mm in diameter, with multicellular hairs externally. Corolla lobes spreading, to 1.5cm long, 5-8mm broad obovate, glabrous. Stamens 5, adnate at different levels in corolla tube, mostly included. Anthers yellow, 1.5mm long. Style 1-3mm long. Stigma 3-lobed. Lobes -1mm long. Ovary glabrous, green, 1.1mm long, superior, 2-3-locular. Calyx densely glandular pubescent, accrescent. Calyx tube to 2mm long, 5-lobed. Lobes linear-attenuate, 8mm long, 1mm broad, connected by scarious tissue for 2-3mm above calyx tube, often with some purplish coloring.
Flowering - April - July, sometimes again in the late fall.
Habitat - Rocky or dry open woods, valleys, thickets, meadows, prairies, glades.
Origin - Native to U.S.
Other info. - This is a popular little plant because of its striking floral displays and the easy manner in which it can be grown. The plant takes readily from seed and produces much seed every year. The plant itself is perennial.
This is an extremely variable plant in nature with no fewer than 6 varieties and forms in Missouri alone and more elsewhere. The varieties are based on the type and amount of pubescence on the calyx and subtending bracts, the shape and size of the leaves, and of course the flower color. I am not going to go into all the varieties and forms here because many of them integrate, further complicating the issue.
This plant is sometimes mistaken for Phlox divaricata L. but this latter species blooms slightly earlier in the year, grows in moist places, spreads by horizontal runners, and has more bluish flowers.

Stems - Vegetative stems decumbent. Flowering stems erect to ascending, to 40cm tall. Both types typically densely pubescent to glabrous. Plants rhizomatous.
Leaves - Of fertile shoots - opposite, sessile, lanceolate, decussate, spaced +/-5cm apart, to 5cm long, 2cm wide, variously pubescent, entire. Of sterile shoots - elliptic to narrowly oblong.
Inflorescence - A fairly compact cyme, sometimes paniculate.
Flowers - Corolla lavender to purple, with tube to 2cm long, glabrous. Corolla lobes 5, spreading, spatulate to obovate, to 2cm long, 1cm wide. Stamens 5, unequal in corolla tube. Calyx tube to 3mm long, densely pubescent to glabrous. Calyx lobes 5, to +3mm long.
Flowering - April - June.
Habitat - Open woods, slopes, moist ground.
Origin - Native to U.S.
Other info. - This is the most common species of Phlox found in the state. It is one of the earliest blooming plants in spring also. The corolla is typically light blue-purple but can vary in color from rose to white. A white flowered form can be seen in the "White Flowers Opposite Page" of this website.
In the glossary you will find the word "divaricate" which means "widely spreading", thus the species name of this plant because of its spreading nature.
Most descriptions of the plant give the stems as glabrous but every plant I have found has been from sparsely pubescent to hirsute.
