Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

Prosartes

Disporum in Michigan Flora.

Like Streptopus and Uvularia, plants are branched, but have leaves pubescent beneath. In addition to the three species known from Michigan, P. lanuginosa (Michx.) D. Don occurs in southwestern Ontario. It differs from the Michigan species by its glabrous ovary even in flower and greenish yellow rather than white tepals. Formerly placed in Disporum, which is now circumscribed to include only Old World species.

1. Tepals copiously purple-dotted; ovary densely glandular-pubescent.

P. maculata

1. Tepals unspotted; ovary hispidulous, especially toward the summit, or papillose.

2. Ovary somewhat hispidulous to essentially glabrous at maturity; leaf margins ciliate essentially to the tip.

P. hookeri

2. Ovary densely papillose; leaf margins not or very sparsely ciliate at and near the tip.

P. trachycarpa
