The cold infusion is a good tonic and stimulant during convalescence from exhausting diseases. A warm infusion is very useful in puerperal, remittent, and other forms of fever, coughs, colds, catarrhs, etc., and is of much benefit in spasmodic diseases, especially colic, cramp of the stomach, and spasms of infants. It has the taste and odor peculiar to the mint family.Īction, Medical Uses, and Dosage.-Pycnanthemum is diaphoretic, stimulant, antispasmodic, carminative, and tonic. The whole plant is used, and yields its virtues to boiling water. ![]() History.-This plant is found in low grounds, dry hills, and plains, from Ohio and Illinois extending southward, and flowering in July and August. Corolla pubescent stamens exserted (G.-W.). Calyx teeth ovate-lanceolate, acute, and with the lanceolate bracts canescently villous and awnless. The flowers are white, in large, terminal, sessile heads. The leaves are sessile, nearly entire, lanceolate, acute at both ends, pilose beneath floral ones not whitened. ME by Magee and Ahles (1999), but specimens are unknown.Botanical Source.-This is an indigenous perennial plant, with long and soft whitish hairs, and a subsimple stem, from 1 to 2 feet in height. Faces of upper stem internodes moderately to sparsely pubescent with short, pilose hairs pubescence of abaxial leaf blade chiefly or entirely confined to the veins ![]() Faces of upper stem internodes conspicuously pilose with spreading hairs pubescence of abaxial leaf blade conspicuous and uniform across the surfaceġb. Mesic to wet-mesic forests, fields, meadows, and roadsides.ġa. ME by Magee and Ahles (1999), but specimens are unknown. There are two leaves per node along the stemĥb. ![]() The leaves are nearly similar in size, prominence of teeth, and length of stalks throughout the stem The leaves are simple (i.e., lobed or unlobed but not separated into leaflets) the leaf blade margin has forward-pointing teeth.the leaves have no leaf stalks, but attach directly to the stem.The leaves are green, with an expanded blade and a leaf-like texture The leaves drop off in winter (or they whither but persist on the plant) The upper side of the leaf blade is relatively uniform in color the leaf blade is linear (very narrow with more or less parallel sides).the leaf blade is lanceolate (lance-shaped widest below the middle and tapering at both ends).the edge of the leaf blade is entire (has no teeth or lobes).The base of the leaf blade is cuneate (wedge-shaped, tapers to the base with relatively straight, converging edges), or narrow the leaf has a distinct leaf stalk (petiole).Opposite: there are two leaves per node along the stem the upper side of the leaf is not hairy, or it has very few hairs.the upper side of the leaf is fuzzy or hairy.The underside of the leaf is fuzzy or hairy The flower has one or more bracts associated with it The fruits do not have thorn-like defensive structuresįinal leaf segment length (compound lvs only)įinal leaf segment length to width ratio (compound lvs only)įinal leaf segment width (compound lvs only) The plant has axile placentation, in which the ovules are attached where the septa of a compound ovary are united, usually on the central axis, or to the septa themselves The fruit is a schizocarp (when dry it splits into sections, each holding one or more seeds) The fruit is dry but does not split open when ripe The fruit is obloid (longer than wide and with rounded ends) the upper lip of the bilabiate corolla has two lobes.the upper lip of the bilabiate corolla has one lobe.The stigmas are positioned at the tip of the style The stamens are not attached to one another The stamens are attached at or near the bases of the petals or tepals The sepals do not have appendages on them ![]() The sepals are green or brown, and leaf-like in texture The petals of the flower do not have folds or plaitsĪll the flowers have both carpels and stamens (synoecious) The petals are thin and delicate, and pigmented (colored other than green or brown) The flower includes two cycles of petal- or sepal-like structures The ovary is above the point of petal and/or sepal attachment
