M.J. Oldham & W.D. Bakowsky 28668; specimen record, replicates at MICH 1556309, NHIC# 10569; identified by M.J. Oldham, !A.A. Reznicek Jan. 2013 as Podostemum ceratophyllum ; rocky rapids; on boulders in rapids; GPS waypoint 51

25m tall tree, currently in fruit. Twigs and seed husk exuding a strong odor. Fruit is a nut surrounded by a large, dense and continuous husk with a rough-ish surface texture, (currently green coloration). Leaves of this individual are pinnately compound in alternate arrangement.

Pleasant smelling plant extending around 5 feet tall, up the fence line. Soil was still slightly moist from a previous rain. This area holds water well. The naturally forested, weedy area was surrounded by many other shrubs and trees.
The plant had yellow and white flowers with opposite, simple oval leaves.

Flowering dogwood is a small deciduous tree growing to 10 m high, often wider than it is tall when mature, with a trunk diameter of up to 30 cm. A 10-year-old tree will stand about 5 m (16 ft) tall. The leaves are opposite, simple, ovate, 6–13 cm (2.4–5.1 in) long and 4–6 cm (1.6–2.4 in) broad, with an apparently entire margin; they turn a red-brown in fall. The flowers are individually small and inconspicuous, with four greenish-yellow bracts 4 mm long. Around 20 flowers are produced in a dense, rounded, umbel-shaped inflorescence, or flower-head, 1–2 cm in diameter. The flower-head is surrounded by four conspicuous large white, pink or red "petals" (actually bracts), each bract 3 cm (1.2 in) long and 2.5 cm (0.98 in) broad, rounded, and often with a distinct notch at the apex. The flowers are bisexual. When in the wild they can typically be found at the forest edge and frequently on dry ridges. While most of the wild trees have white bracts, some selected cultivars of this tree also have pink bracts, some even almost a true red. They typically flower in early April in the southern part of their range, to late April or early May in northern and high altitude areas.
