Addendum: Well-Hidden

I should have written a little more about Obolaria in yesterday’s post, which I realized when someone asked a question in the comments.

The thing is, very little is known about this plant. I was able to find one paper* on the subject; in the introduction, the authors state:

Although morphological descriptions of O.virginica exist in various floras (e.g., Radford et al. 1968, Fernald 1970, Wood and Weaver1982, Gleason and Cronquist 1991), information about reproductive capacity or ecological parameters that might influence growth and development is lacking. For example, no information exists about the pollination biology of pennywort, nor have there been any studies to examine basic soil parameters to determine optimal growing conditions of this species.

The paper is interesting, but has no further discussion of pollinators.

I’m not patient enough to sit and watch a stand of Obolaria to see what, if any, insects come to visit. It would be an interesting project, though.

One thought on “Addendum: Well-Hidden

  1. Pollinators are a strange group that does not even fit into a group. I sometimes write about flowers that are pollinated by flies . . . so they smell like what flies want; ICK! Those that are pollinated by bats smell like over-ripe fruit. Some flowers use infrared or ultraviolet that we can not see, or fragrances that we can not smell. There are so many flowers out there that I can not figure out; but I do not need to as long as ‘they ‘ know what they are doing.
