mid-stem leaves in comparison photo: S. flexicaulis (L), hybrid (centre), S. caesia (R). Lower stem leaves of hybrid were broader, with obvious lateral veins (see e.g., plant at bottom left of photo 1)

All of the wild gingers (Asarum canadense sensu lato) I was able to find throughout this sandy floodplain forest had glabrous, short-acuminate, strongly reflexed petals like this plant. I am not sure how widespread this variety is in Canada, but certainly is expected to be Carolinian in distribution.

WDV 255 (to UWO).

Glomerules not cylindrical, leaves with callous apices, inflorescence branches spreading more than 90 degrees (per FNA key). Growing with Comandra umbellata, Antennaria parlinii ssp. fallax, and across the road from a population of Thalictrum thalictroides, another locally rare species of well drained, sandy soil. This species has never been recorded in Niagara, Ontario but is known from adjacent Niagara County, New York.

M.J. Oldham & W.D. Bakowsky 32714; specimen record, replicates at MICH 1459300; identified by M.J. Oldham, !A.A.

M.J. Oldham, S Varga, WD Bakowsky, GM Allen, DA Sutherland 18080; specimen record, replicates at DAO, MICH, NHIC# 00025; identified by M.J. Oldham, !A.A. Reznicek 1996 as Adenocaulon bicolor ; 300-400 mature plants on fairly steep wooded slope of W Birch, Abies, Thuja; flowering; growing with Aster macrophyllus, A. cordifolius, Carex eburnea, Abies balsamea

I found a few of these goldenrods in a mesic sandy site in a young oak-maple forest. They superficially resembled rough goldenrod (Solidago rugosa) but they were completely glabrous except for a few hairs in the inflorescence and along major veins on the abaxial leaf surfaces. Careful examination of the plants using the Flora of North America description made me very confident that this is, in fact, elm-leaved goldenrod (Solidago ulmifolia), and it resembles the individuals of that species which I've seen in the States. Proximal cauline leaves (i.e., lowermost leaves) were senesced at anthesis.

Essex County, Ontario, Canada.

Hairy leaves, sheaths, and glumes. Keys best to Phalaris aquatica using FNA key, but Lemmas are awned which seems inconsistent with that species. Habitat fits though - disturbed riparian moist meadow with carex spp, Juncus spp, Scirpus atrovirens,elc.

Large, old, badly damaged tree about 10 km north of perhaps the northern-most naturally occurring population of this species, suggesting there are or were shumardii trees near the location of this hybrid.

Note that the name Quercus x riparia refers to the cross between Q. shumardii var. schneckii and Q. rubra. There is does not seem to be an official scientific name for the hybrid between Q. shumardii var. shumardii (one of the putative parents of this tree) and Q. rubra, so I'm using Q. x riparia as a place-holder for this observation.

Thanks to Albert Garofalo for bringing me to this site.
