The conservatory’s orchid collection, which began as a gift from Mrs. Anna H. Clise in 1921, is also found in the Palm House. Orchids are a large and diverse flowering plant family composed of more than 20,000 species. The conservatory’s collection includes representatives of the largest genera – "Bulbophyllum", "Epidendrum", and "Dendrobium" – as well as commonly cultivated genera such as "Cattleya" and "Phalaenopsis".

Portia labiata males use tactics to survive copulation, but sometimes females outwit them. Before being mature enough to mate, juvenile females mimic adult females to attract males as prey. When hunting, "P. labiata" mature females emit olfactory signals that reduce the risk that any other females, males or juveniles of the same species may contend for the same prey. As in most species of the genus, the bodies of female "Portia labiata"s are 7 to 10 millimetres long and their carapaces are 2.8 to 3.8 millimetres long. Males' bodies are 5 to 7.5 millimetres long, with carapaces 2.4 to 3.3 millimetres long.
