Description
Marshallia mohrii grows to around 1-2.5 ft in height, with 2.5 cm wide tubular-shaped flowers found in 2-6 flower masses. The flowers can range in color from white, to pale pink or lavender. The leaves of the plant are lanceolate to ovate in shape, ranging from 6-10 cm long and 2 cm wide, with three parallel veins. The leaves are larger and more numerous near the base of the stem. (Patrick, Krakow, 1995)
The plant typically flowers from mid-May through June, with fruit being produced in July and August. (Tsao, Van Lonkhuyzen, 2000) The fruit is a 5-angled, 10-ribbed achene, about 4 mm long, with a hairy, resin-dotted surface. The fruit is topped by a crown (pappus) of five, narrowly triangular, sharply pointed scales, which are 1-3 mm long. The fruits are found among the sharply pointed bracts (chaff), which persist on the flower head. (Patrick, Krakow, 1995)

“Whose are the truly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the month’s labor in the farmer’s almanac, to restore our tone and spirits.”
—Henry David Thoreau (1817–1862)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
