Recent phylogenetic analysis of the Old World species of Passiflora has indicated that two monotypic genera in the Passifloraceae, Hollrungia and Tetrapathea, are strongly supported as belonging to the genus Passiflora. Additionally, a new species from Australia was found to belong to the same clade as Hollrungia and Tetrapathea. Consequently, a taxonomic revision is presented here of Passiflora subgenus Tetrapathea including these three taxa. Tetrapathea tetrandra, the type of Passiflora subgenus Tetrapathea and historically recognized as both T. tetrandra and P. tetrandra, is formally accepted here as P. tetrandra. The single species of Hollrungia, H. aurantioides, is transferred to Passiflora subgenus Tetrapathea as P. aurantioides. The new and so far unnamed species in Passiflora subgenus Tetrapathea from Australia is also described as P. kuranda sp. nov.

“Plant blindness” is defined as the failure to appreciate the fundamental importance of plants. To address this phenomenon, we created the Pet Plant Project (P3) where students grow an unknown plant from seed, monitor development, and relate lecture concepts to their plant on a daily basis. A qualitative survey was administered and analyzed to evaluate student responses to the experience. Themes in the analysis, identified across 209 student-participants at Tennessee Tech University, included positive reinforcement of lecture material, a new-found appreciation for plants, responsibility and pride related to plant care, a continued desire to grow plants, and more. Statistical results included: 73% of students noticed plants more after the project; 76% planned to grow plants in the future; and 68% made a connection with their own plant that bolstered engagement in course materials.
