Q: About Utricularia subgenus Utricularia section Steyermarkia

A: Uh oh, another section of lithophytes. If you have been paying close attention, you should have noticed that the lithophytic and rheophytic species are usually insanely bizarre. This section, though, is relatively conventional. It is similar to section Setiscapella (the Utricularia subulata section that we talked about recently) but its species have a different structure to their seeds.

Ellison & Adamec (2018) differ in their treatment from mine, only in the inclusion of Utricularia cochleata, which I consider a synonym of Utricularia steyermarkii, below.

Utricularia aureomaculata
This species is known only from a few collections from Ptari tepui, Amaruay tepui, and Aparaman tepui. Alas, botanists visiting these sites are always so dazzled by the Heliamphora they do not stop to study the exquisite Utricularia. It looks rather like the oh-so-common U. subulata, which probably counts as another strike against it.

Utricularia steyermarkii
Again, known only from a few collections, this time near Rio Churún and Acopán tepui. Easily mistaken for U. subulata by uncaring Heliamphora botanists.

Utricularia cochleata C.P.Bove is probably just a synonym of this species.
