STUDIES IN THE MORPHOLOGY OF RICCARDIA PINGUIS
TLDR
Plants of this species are somewhat more abundant on the railroad right-of-way through the swamp prairie bordering Lake Waubesa and extending westward for about a mile, and at all these stations the plants are protected from the summer sun but are favored with nearly full sunlight during the fall and early spring-the seasons during which vegetative growth appears to be most rapid.
