Individuals prefixed with “TE” represent T. eriantha plants and individuals prefixed with “TV” represent T. versicolor plants. Those individuals with a three-digit label followed by a dashed no. represent plants that were collected in the field after open pollination was allowed to occur, generating the intraspecific families. They were then brought back to the greenhouse where cross-pollinations were performed to generate the interspecific families. Individuals numbered with a “TE” or “TV” prefix, followed by a four-digit numeral represent those that were propagated from seed in a laboratory setting and grown in a controlled environment facility where the crosses were performed. Crosses are written as female × male. ANOVA indicated that there were significant differences among the groups of hybrid families at P < 0.001.

^c Tukey's multiple comparisons test confirmed that there were significant differences between the groups at P ≤ 0.01 (Zar, 1999). The T. eriantha intraspecific hybrids and the T. eriantha × T. versicolor F₁s were not significantly different at P ≤ 0.01.
