During the City Nature Challenge last weekend we organised bike field trips here in the coastal Amazon region with our students. One of them photographed a native gymnosperm, a species of Gnetum. These are frequently not recognized as such — at first glance, they look like any angiosperm liana, especially in sterile conditions. However, the swollen nodes of the seed-bearing strobili give them away when examining more closely.
