Horse nettle

Here is a nice patch of horse nettle (Solanum carolinense). It's growing in a parking lot divider off 18th St. near County Road 350S. Usually you notice horse nettle in your back yard when you step on it going barefoot. Pictures taken July 30, 2010.

Green Dragon

This green dragon (Arisaema dracontium) is in Celery Bog Park in the woodlands between the entrance drive and the pond's edge. The presence of green dragon indicates a higher quality woodland. Picture taken July 13, 2010.

Fifty years ago there were hardly any woods here. Much of the park land has restored itself without human effort, save for the removal of invasives like honeysuckle. The planet will heal itself if left alone.

Nearby the green dragon and more numerous are Jack-in-the-pulpit (Arisaema triphyllum) with leaves as big as plates-o'-shrimp.

Napaea dioica

This Napaea dioica, or glade mallow, is growing on the Wabash Heritage Trail right across from the softball fields at Lyboult Park. Of Napaea dioica, Deam's Flora of Indiana states: "Local and very rare. Alluvial banks of the Wabash River and moist roadsides." So it is that even the rarest of plants may inhabit urbanized areas. Pictures taken July 11, 2010.

Purslane seeds close up

This is a close-up look at the tiny seeds of purslane (Portulaca oleracea) sitting in their seed capsule.

The seeds came from this purslane plant growing in the sidewalk on Main Street.

This is a closer look at the purslane seeds from the plant pictured above. The green plant they are laying on is not purslane but rather an Oxalis stricta seed capsule. Pictures taken July 9, 2010.

White pigeon

This white pigeon (Columbia livia) showed up in downtown Lafayette, I don't know whether it's an escaped domesticated pigeon or a white form of the pigeons you normally see here in the city. Picture taken July 5, 2010.

Wild Bergamot

This Monarda fistulosa appears along the southern trail in Celery Bog Park. Monarda fistulosa is a common wild plant with showy fragrant flowers. It grows totally wild in many places in Tippecanoe County although this here is likely the result of a restoration effort. The population of Monarda should persist in this area as long as the habitat remains unaltered. Picture taken July 3, 2010.

High water mark of June 23

The flood levels of the Wabash at Lafayette last peaked on June 23 at 19 feet and the river has been receding ever since. The high water mark is visible in this picture of the Lafayette side of the river, taken from the pedestrian bridge on June 29, 2010. The Wabash river level at the time of the picture is about 9 feet.
