CATALOGUE OF PLANTS. 135 406 U. gibba, L. Pond shores; rare. Breakneck Ponds (F. M. Day);—Somes Pond (Rand). A form from mud flats, Somes Pond (Rand), closely approaches U. biflora, Lam., and may perhaps prove to be that species. “The flower has the spurs of U. biflora very decidedly, but the foliage and the bladders are those of U. gibba. The spur here is oblong, narrow, not curved but projecting straightwise, and the perianth is somewhat larger than is gen- erally the case in U. gibba. Other specimens with foliage and bladders better represented might show this to be U. biflora, but at present it is safer to call it ‘U. gibba verging towards U. biflora in flowers.’” Dr. Thomas Morong in litt. 407 U. intermedia, Hayne.
