Flowers - Corolla +6cm in diameter. Petals 5, deep rose-pink with white at very base, free for most of length but united to stamen column, +3cm long, +2cm broad, glabrous, blunt to emarginate at apex. Stamen column 1.3cm tall(long). Filaments deep rose-pink. Anthers pale yellow. Styles 1cm long, deep rose-pink, at first hidden by stamen column. Ovary of 15-20 carpels in a ring to 5mm in diameter. Calyx deeply 5-lobed. Tube to 3mm long. Lobes to -2cm long, lanceolate but involute in upper half, with prominent white venation, hirsute to pilose, greenish near apex, purplish-green near base, ciliate-margined, tomentose internally near base. Fruit ring to 10mm broad, 1 seed per carpel.
Flowering - March - August.
Habitat - Prairies, open woods, roadsides, railroads.
Origin - Native to U.S.
Other info. - This is a striking plant with bright flowers which only last a day and then dry to a more purple color. It is gaining popularity in cultivation and is easy to grow.
Like I've mentioned before, this family typically has flower parts in multiples of five, (the carpels, for example), and that along with the recognition of the stamen column is a good way to start recognizing the family.

Inflorescence - Terminal umbel with +/-50 flowers, nodding when immature. Pedicels much longer than the flowers, glabrous, purplish in strong sun, to +2cm long.
Flowers - Perianth pink, spreading, 6-parted. The tepals to 7mm long, elliptic, typically acute at the apex, glabrous. Stamens 6, erect, exserted beyond the perianth parts. Filaments terete, pink, glabrous. Anthers yellow when fresh, quickly becoming brown. Style pink, terete, glabrous, shorter than or equaling the stamens.
Flowering - July - November.
Habitat - Glades, bluffs, open dry woods, roadsides.
Origin - Native to U.S.
Other info. - This showy species can be found in the Ozark region of Missouri. It is the latest blooming onion in Missouri and is easy to identify in the field. The papery-covered bulb, pink flowers, and flat, persistent leaves are good characters to look for.
A. stellatum can sometimes be confused with another plant, A. cernuum Roth, because both can have nodding inflorescences (cernuum means "nodding"). The inflorescence of A. stellatum only nods when it is immature and will become erect with time. The difference between the two plants is in the flowers. A. stellatum has a spreading and open perianth. The perianth of A. cernuum is campanulate (shaped like a bell).

Stems - From a bulb. Bulb covered with a dense network of criss-cross fibers. Fibers tan in color. Bulb to 3cm long, ovoid. Aerial stems to +40cm tall, erect, glabrous, terete, single to multiple from the base, simple.
Leaves - Basal, linear, glabrous, to +40cm long, 2-7mm broad, green to pale green, with a broad shallow groove adaxially, sometimes folding at the base, pale green to whitish at the base.
Inflorescence - Terminal umbel of zero to many flowers. Sometimes the flowers replaced with reddish bulblets. Sometimes inflorescence a combination of bulblets and flowers, or all flowers. Bulblets sessile. Flowers with pedicels to +4cm long, glabrous, erect. Pedicels much longer than the flowers. Bud of inflorescence covered with a scarious tan bract. Bract persistent at the base of the umbel after anthesis.
Flowers - Tepals 6, pink to white, glabrous, oblong-lanceolate, to +/-8mm long, +/-3mm broad. Stamens 6, erect. Filaments pinkish, glabrous, expanded at the base, adnate to the base of the tepals, +/-5mm long. Ovary subglobose, glabrous, 3-locular. Style glabrous, +/-5mm long, pinkish. Ovules 3-4 per locule.
Flowering - April - July.
Habitat - Glades, bluffs, open woods, prairies, disturbed sites.
Origin - Native to U.S.
Other info. - This showy plant can be found throughout Missouri. It is especially common in glade areas of the Ozarks. The plant has a strong onion scent and is edible.
Many authors have tried to split this species into varieties based on the number of flowers or bulbs produced. I will not go into these here as the varieties are probably not valid. Bulb producing plants can be found growing right next to flower producing specimens.
Other Allium species are similar in appearance to this one but only A. canadense has the characteristic fiber coating on its bulb. Be careful not to remove the coating when digging the plant up to check.

Blade elliptic to lance-ovate or lance-oblong, serrate, +/-11cm long, +/-4cm broad, acute, pubescent below, sparse pubescent to glabrous above. Leaf tissue abruptly contracted at base and creating a slight wing on petiole to 1mm broad.
Inflorescence - Terminal spikiform arrangement of verticillasters to +30cm tall(long). Verticillasters with +/-5 flowers each. Flowers on pedicels 2mm long. Pedicels and axis tomentose. Each flower subtended by a lanceolate-attenuate bract to +/-8mm long.
Flowers - Corolla highly irregular, bilabiate, light pink to purplish. Corolla tube greenish, 5mm long, dense glandular pubescent and pilose at apex. Upper lip with 2 lobes erect and shaped as horn-like appendages. Lobes to 4mm long(tall). Lower lip with two lateral rounded lobes and one large cupped central lobe. Lateral lobes to 3mm long. Central lobe to 7mm long, 6mm broad, glandular externally, often with two pinkish-purple spots near base internally. Stamens 4, didynamous, well exserted from corolla, deflexed. Filaments greenish-white, 1.4cm long, pubescent near base, glabrous above. Anthers reddish-brown, .7mm broad. Style 1.5cm long, white, glabrous, exserted from between opposing pairs of stamens, down-curved. Stigma 2-lobed. Ovary of 4 nutlets. Nutlets green and glabrous in flower. Calyx bilabiate.

Lobes attenuate, 3mm long. Calyx accrescent.
Flowering - June - September.
Habitat - Prairies, wet meadows, thickets, streambanks, railroads.
Origin - Native to U.S.
Other info. - This species can be found throughout Missouri. The unusual flowers of this species make it a simple to ID in the field. The flowers are also quite showy and make the plant much deserving of cultivation. Flying insects are attracted to the flowers and the large central lobe of the lower corolla lip serves as a platform for insects to land on. The two purplish spots on the lobe are like runway lights guiding the insects to the flower.
The leaves of T. canadense have a slightly fowl odor when crushed.
Some authors, including Steyermark, split the species into different varieties but they are so similar that I won't go into them here.

Inflorescence - Axillary bracteate fascicles of typically 3 flowers. Peduncles to 1cm long in fruit, 1-2mm long in flower, 4-angled, glabrous to sparse pubescent. Bracts subtending the flowers foliaceous, accrescent, lanceolate, 3-nerved, to 8mm long and 3mm broad in fruit, strigose externally, glabrous internally.
Flowers - Corolla 4-lobed, funnelform, 4-5mm long, pinkish-purple. Corolla tube to 3mm long, whitish at the base, glabrous externally and internally. Corolla lobes acute, spreading, -2mm long, 1mm broad, glabrous. Stamens 4, exserted, adnate at the apex of the corolla tube. Filaments white, glabrous, 1.1mm long. Anthers purplish, .3mm long. Style exserted, glabrous, translucent, 4mm long. Stigmas 2, short (.1mm long). Calyx 1.1mm long in flower, accrescent, 6-lobed, pubescent, green. Calyx lobes triangular, .3mm long. Fruits mostly on stalks to .5mm long, pubescent. slightly rectangular in cross-section, to 4mm long, 2-locular, 2-seeded.
Flowering - April - May.
Habitat - Openings in woods, along creeks, disturbed sites, fields, roadsides.
Origin - Native to Europe.
Other info. - This little species is uncommon in Missouri. It is found only in several southwestern counties. The plant, at first glance, appears to be in the genus Galium but its purplish flowers, funnelform corolla and bracteate inflorescences separate it from that genus. The plant can be quite weedy if left un-checked and it will most certainly expand its range in Missouri with time.

Flowers - Corolla bilabiate, pinkish, pubescent externally. Corolla tube to +/-2.3cm long, constricted at base where surrounded by calyx, expanded beyond calyx. Upper lip 8-9mm long, 7-8mm broad, truncate to rounded at apex, the sides parallel. Lower lip 3-lobed. Lateral lobes 3-4mm long, 3mm broad. Central lobe 5-6mm long, 4-5mm broad, with purple spotting internally,(purple coloration extended into throat of corolla). Stamens 4, didynamous, ascending under the upper lip of the corolla. Filaments adnate for most of length(seemingly by dense pubescence), white or tinged with pink. Anthers purplish-brown, 1.7mm long. Style inserted between stamens (and slightly longer), white, glabrous, 2.5cm long. Stigma 2-lobed, filiform.Ovary 4-parted, green, glabrous. Calyx tube 6mm long(in flower), dense pubescent, pitted internally, 5-lobed. Lobes equal, acute, 2.2mm long(in flower). Calyx accrescent, to +1cm in fruit. Nutlets to +3mm long.
Flowering - May - September.
Habitat - Prairies, glades, wooded bluffs, streambanks, railroads.
Origin - Native to U.S.
Other info. - This is a popular and well known native plant. It is widely cultivated and used in butterfly and landscape gardens. The plant has many varieties in cultivation. A common name for the species is "Obedient Plant" because the plants flowers can be rotated or twisted to new positions and will remain this way and continue to grow.
Steyermark breaks the species up into a couple of varieties and forms based on leaf size and flower color. I won't go into those here.
