158 5 Corolla rose pink; inflorescence 1 (?2)-flowered; bract at base of pedicel tubular, attached circumferentially around stem; aerial leaves (when present) terete, septate Utricularia resupinata Fig. 160 �C Corolla yellow (sometimes fading white); inflorescence (1?) 2?15-flowered; bract at base of the pedicel peltate or ovate, attached on one side of the stem; aerial leaves (when present) flattened, not septate 6 6 Pedicels subtended by a single ovate (attached at base) bract; pair of bracteoles present, bracteoles linear [http://www.selleckchem.com/products/SNS-032.html SNS-032 manufacturer] to lanceolate, a little longer than the bract; corolla spur oriented downward or backward, at right angle to lower corolla lip Utricularia cornuta Fig. 157 �C Pedicels subtended by a single peltate (attached in middle) bract, unattached at either end; pair of bracteoles absent; corolla spur oriented forward, essentially appressed to lower corolla lip; aerial leaves (when present) with subacute or obtuse apices Utricularia subulata Fig. 162 View it in a separate window Key adapted from Godfrey and Wooten (1981), Taylor (1989), and Weakley (2012). Note: Traditionally, in the southeastern [http://en.wikipedia.org/wiki/Enol Enol] United States, U. biflora and U. gibba have been recognized as distinct species (Radford et al. 1968). However, Radford et al. (1968) described the two as ��doubtfully distinct�� and neither Godfrey and Wooten (1981), nor Taylor (1989), recognized a distinction. Here, we follow Weakley (2012) in provisionally recognizing the two species as distinct, pending a world-wide revision. During the present work, only U. gibba was encountered in the field, but U. biflora (bracketed in key below) is keyed here due to its morphological similarity, overlapping range, and similar habitat requirements.
