Room One houses a mature collection of plant specimens that are useful for students to study in teaching labs. There is also a collection of ferns that are used for genetic research (Wolf lab). Included in this research is the fern Lonchitis hirsuta, native to Puerto Rico, which is difficult to cultivate. In addition, there are a group of primitive plants which include Equisetum, Selaginella and Psilotum that aid in student's understanding of the evolution of plants. A small group of Insectivorous plants are represented and always seem to fascinate the students.
