3.1.2 Examples of Hyperendemics
A couple of species are represented in the nature by a last individual only. For
example, no more than a single mature individual of the vascular plants Aegiphila
caymanensis, Bhesa sinica, Brighamia insignis, Carpinus putoensis,
Commidendrum rotundifolium, Cyanea truncata, Dichapetalum letouzeyi,
Holmskioldia gigas, Hyophorbe amaricaulis, Pennantia baylisiana, Pritchardia
munroi, Ramosmania rodriguesii, and Sorbus parviloba have recently been
observed (IUCN 2019c; also for the following examples if no other references cited).
Table 4 Endemic and non-endemic vascular plant taxa in habitats of Europe (according to Janssen
et al 2016, and recent versions of EvaplantE and PEARL); taxon in this case refers to species,
subspecies or group of apomictic microspecies of vascular plants. Note that many taxa occur in
more than one habitat type
