Therefore, most seeds produced by lilies in bear digs fall onto bare soil, which is ideal for germination and establishment of Erythronium
seedlings (Caldwell 1969, E.
Variation in pollen size, fertilization ability, and postfertilization siring success in Erythronium
Claytonia lanceolata, Erythronium
grandiflorum, and Mertensia brevistyla formed an early cohort; Delphinium nuttallianum, Lathyrus leucanthus, and Potentilla pulcherrima formed a middle cohort; and Eriogonum subalpinum, Ipomopsis aggregata, Campanula rotundifolia, and Seriphidium vaseyanum formed a late cohort.
Cruzan (1990) suggested that small pollen grains of Erythronium
have a higher surface-to-volume ratio; thus they would dry more quickly than large ones and their life expectancies would be shorter.
Post-fertilization causes of differential success of pollen donors in Erythronium

Cryptic self-incompatibility, Erythronium

caerulea, preventing pollination of late flowers did not increase seed set of early flowers in Erythronium
grandiflorum nor in Clintonia borealis, while preventing pollination in early flowers increased seed set of late flowers in both species (Thomson 1989).

Seed dispersal in Erythronium
This week, I saw erythronium
blooms start to open up and trilliums display their wonderful flowers.
One of the plant specimens is the uncommon Erythronium
mesochoreum (prairie trout-lily) which was collected by Dr.
