Discussion:
The fact that the calyx is continuous with the pedicel suggests that this species is an ally of the widespread T. floribunda H. B. K., from which it differs in such obvious respects as its broader leaves, greatly reduced and glomerulate inflorescences, narrowly winged calyx and corolla, and longer corolla and stamens. That the corolla is winged (although very obscurely so) indicates an affinity of the new species with Anthopterus Hook., where, however, the wings are obvious and manifestly veined. From another allied genus, Calopteryx A. C. Smith, T. lateriflora is excluded by its continuous calyx and also by its very narrow corolla wings. The discovery of such new species as this and the above-described Calopteryx sessiliflora, however, suggests that the winged corolla cannot be safely utilized as a character of generic value in the family.
