Family - Portulacaceae
Stems - From stout taproot, multiple from base, prostrate, greenish with some red tinge, branching, succulent, herbaceous.
Leaves - Alternate, sessile or very short petiolate (+/-1mm), glabrous, oblanceolate to obovate, obtuse to truncate at apex, tapering slightly to base, entire, glabrous, succulent, to 3cm long, 1.2cm broad.
Inflorescence - Single or few flowers terminating stems.
Flowers - Petals 5, yellow, glabrous, 3-4mm long, 2.5-3mm broad, distinct. Stamens 6-10. Filaments 1mm long, translucent yellow, glabrous. Anthers yellow, .2-.3mm broad. Style 5-lobed, 1.1mm long, glabrous. Calyx tube to 2mm long, glabrous, green, 2-lobed, with transverse groove. Lobes subequal to unequal, to 4mm long, glabrous, acute. Capsule circumsissle, to +5mm long (tall). Seeds many. Placentation free central.
capsules with seeds.
Flowering - June - November.
Habitat - Cultivated and waste ground, rocky bluffs, glades. roadsides.
Origin - Native to Eurasia.
Other info. - This small plant is becoming common throughout Missouri. The succulent nature of the plant allows it to survive in habitats barren habitats.
Although I have the flower parts labeled as "petals", "sepals", and "calyx" above, this is not technically correct. The perianth is actually composed of an involucre of 2 bracts - the "sepals" above, and 4-6 petaloid tepals - the "petals" above. The ovary is partially inferior.
This species is edible (it's quite tasty) and is often called "Pusley." It was also used traditionally as an ointment for burns.

Leaves - Alternate, petiolate. Petioles of lower leaves to 15cm long, hollow, sparsely to moderately pubescent. Blade pubescent above and below, with ciliate margins, to +15cm broad, +8cm long, palmately lobed, each lobe again divided. Ultimate leaf divisions 2-3mm broad, linear to lanceolate.
Inflorescence - Terminal raceme to 15cm tall(long). Pedicels subtended by attenuate bract. Bracts to 9mm long, 2mm broad at base.
Flowers - Pedicels to 2cm long, densely pubescent. Corolla zygomorphic, typically +/- 3.5cm long and broad. Calyx of 5 sepals. Sepals deep blue-purple(violet) to whitish. Upper sepal with spur to 2cm long. Petals 4. Lateral petals bearded on outside and slightly covering stamens. Upper petals spurred, to -2cm long, lighter blue-purple to whitish. Stamens +/-20. Anthers brownish-black, to 1.5mm long. Filaments white, glabrous, to +6mm long, flattened below and broadest at base. Ovaries pubescent, 4mm long, 1.2mm in diameter.
Fruit - Follicles up to 2cm long, 3 per flower.
Flowering - April - June.
Habitat - Rich, moist woods, slopes, ravines, streambanks.
Origin - Native to U.S.
Other info. - Everyone likes this genus because of the interesting and striking flowers. D. tricorne is a fairly small plant but it produces great color. Many pants in the genus are cultivated.
This species can be toxic.
Steyermark lists the above plant as form tricorne, having flowers which are all deep blue or with some white. A second form, form albiflora Millsp., has flowers which are entirely white. I think a third form may also exist, but I don't know what it is.
Here's a look at a white perianth:

Family - Scrophulariaceae
Stems - To +40cm tall, herbaceous, single or multiple from base, branching above or not, hollow, semi-succulent, from fibrous roots or with weak taproot, with two opposing longitudinal lines of pubescence below, scattered glandular pubescent above.
Leaves - Opposite. Lowest pairs(s) petiolate, (the petiole ciliate margined, to 1.5cm long), blade to +2cm long, 1.5cm broad, toothed, narrowly ovate. Upper leaves sessile, clasping, lanceolate, coarsely toothed, to +5cm long, +2cm broad, very sparsely pubescent (mostly on midrib) to glabrous.
Inflorescence - Terminal whorls or single axillary flowers. Whorls subtended by linear bracts to -1cm long. Pedicels to 1cm long in flower, much elongated in fruit to +3cm long, pubescent.
Flowers - Corolla bilabiate, tubular, to +1cm long. Upper lip two lobed, 6-7mm broad. Lobes lighter in color from whitish to lavender, deflexed at the apex. Lower lip three lobed with folded central lobe enclosing stamens and and style, blue-purple, more broad than upper lip. Stamens 4, borne at base of corolla tube, one pair from upper lip, one pair from lower lip (didynamous). Filaments white, glabrous, to 6mm long. Anthers of stamens from lower lip yellow, to 1mm long. Anthers of stamens from upper lip brownish, to +1mm long. Style filiform, to +5mm long. Ovary globose, 4-valved. Fruit a globose capsule to +6mm in diameter, +/-4 seeded. Calyx campanulate, persistent in fruit. Tube to 3mm long. Lobes 5, 4mm long in flower (5-6mm long in fruit), subequal, 2-3mm broad at base, mostly glabrous but sometimes very sparsely pubescent. Margins serrulate.
Flowering - April - June.
Habitat - Moist low woods, streambanks.
Origin - Native to U.S.
Other info. - I like most of the plants from this family and Collinsia is no exception. This common little plant has brilliant flowers and a striking display for a plant its size. I don't know if it is cultivated regularly but it should do well for people with shaded moist locations in their yards (areas which are typically tough to plant). Remember - Don't collect the plant, just some of the seeds.

Family - Balsaminaceae
Stems - To 1.5m tall, branching above, erect, herbaceous, easily broken, succulent, glabrous, somewhat glaucous, hollow when larger.
Leaves - Alternate, petiolate. Petiole to +/-5cm long, glabrous. Blade ovate to elliptic, shallow serrate, to 10cm long, +/-5cm broad, somewhat glaucous. Teeth of blade with whitish mucro at apex.
Inflorescence - Clusters of 1-3 pedicillate flowers from leaf axils. Pedicels to 3cm long, sometimes with one or two small scale-like bracts.
Flowers - Petals 5, appearing as only 3 petals because of the union of the lateral petals, orange-yellow. Sepals 3, orange-yellow. Larger sepal with spur to +1mm long. Stamens 5, connate around stigma. Pistil 1. Ovary 5-locular. Capsules exploding(elastically dehiscent) when touched, to 3cm long, 1cm wide.
Flowering - May - October.
Habitat - Moist ground, low woods, slopes, stream banks, ravines.
Origin - Native to U.S.
Other info. - Everyone loves to play with the elastically dehiscent seed pods of this plant and it's relative I. pallida Nutt. The pods give a little "pop" when touched, and the seeds fly a pretty good distance. The stems of the plant are easily broken and contain a highly mucilaginous fluid which is supposed to remedy skin irritations caused by other plants. How convenient that this species shares the same habitat as the "Stinging Nettles" (Urtica and Laportea).
In case you're wondering, this is the same genus as the common cultivated Impatiens seen at nearly every garden shop. Few people notice that the flowers of those plants are also spurred like I. capensis.

Family - Portulacaceae
Stems - From a taproot, multiple from base, branching, erect to ascending, herbaceous, succulent, terete, to +8cm long, glabrous but with tufts of pilose hairs in the leaf axils. Hairs white, to 3mm long.
Leaves - Alternate, petiolate to subsessile, succulent, terete to slightly compressed, with a bluish-green tint, to -2cm long, acute. Petioles to 2mm long.
Inflorescence - Terminal cluster of 2-6 flowers. Cluster subtended by a whorl of leaves. Flowers sessile, surrounded by dense white pilose hairs.
Flowers - Petals 5, wine-colored, glabrous. Stamens 10, in a ring at the edge of the receptacle. Stigma 5(4)-lobed. Style glabrous. Ovary half inferior. Placentation basal. Sepals 2, greenish or with a purplish tint, acute, entire, broadly ovate to orbicular, +/-2mm long and broad. Fruit a circumsissle capsule.
Flowering - May - October.
Habitat - Glades, rocky bluffs.
Origin - Native to U.S.
Other info. - This striking little plant is found in a handful of counties in western Missouri. Since it is succulent, it survives well on glades where water is scarce. Given good growing conditions, the plant can form fairly large mats. It would do well as a rock garden plant in cultivation.
The flower morphology looks typical but actually isn't. The petals and sepals are not true organs in this genus but are called such to simplify descriptions.

Family - Portulacaceae
Stems - To 30cm tall, herbaceous, succulent, glabrous, erect to sprawling, rarely rooting at nodes.
Leaves - Alternate, terete to somewhat flattened, linear-oblong, to 5mm wide, 1.3cm long, succulent. Tufts of stiff bristles present at base of leaves.
Inflorescence - Single flower terminating stem, often with involucre-like whorl of leaves at base of flower.
Flowers - Corolla red, rose, pink, orange, yellow or white. Petals to 3cm long, 5 to +30 in number. Stamens +/-40.
Flowering - July - September.
Habitat - Cultivated and possibly escaped to dry waste ground of roadsides and railroads.
Origin - Native to Argentina.
Other info. - This little plant is a survivor. I have friends back in Florida that frequently chop the plant up into tiny bits and then spread the pieces along a brick sidewalk. Within days there are new plants coming up everywhere. This is something to keep in mind if you are thinking of planting the plant in your yard.
The flowers are very striking and new colors are always being developed in cultivation. This species is a "bread and butter" plant of local garden centers.
The plant is capable of growing in dry neglected conditions.
