--><p>The basal tubercles on the petals of <i>Orthilia</i> are unique among Monotropoideae. On fresh or rehydrated flowers they are about 0.2–0.3 mm in diameter and 0.1–0.2 mm tall. The tubercles appear as obscure thickenings on dried specimens. H. F. Copeland (1947) found no evidence of glandular activity associated with these tubercles and speculated that they may influence the opening of the flowers, as do the lodicules of grasses.</p><!--
