Q: More Latin American Pinguicula

A: Here we enter an area where we know surprisingly little about Pinguicula. Many of these species are endemic to Cuba, and as such are difficult for botanists to visit because of a raft of permits required. USA botanists are essentially prohibited from doing science in Cuba because of USA laws that are truly bizarre and inconsistent with reality. In any event, many of these species are highly localized in range, and are probably very endangered. They would be very interesting to learn more about.

Pinguicula antarctica--Despite this plant's name, it does not occur in the continent of Antarctica. I really shouldn't have to say this, but this plant's name has inspired at least one internet April Fool's joke, and has confused a number of young acolytes just starting to study the genus. Although it may in fact be the carnivorous plant with the most southerly range, it certainly does not grow on the continent of Antarctica.

Pinguicula elongata--A very striking plant with erect, elongate leaves. I wonder if it possibly captures prey using a hybrid foraging strategy, similar to the pitfall-sticky trap method used by Drosophyllum. Is it possible it uses its short, early-season leaves to make a bowl-shaped chamber, almost like that of a pitcher plant? Casper put this plant in its own subsection (Heterophylliformis), but more recent research by Beck et al. (2008) suggests this plant is more closely related to Mexican species, and should be removed from section Ampullipalatum altogether.

Pinguicula filifolia--A shortlived species that has long, delicate, threadlike leaves. I have been unsuccessful at propagating this vegetatively or via selfing, which means that every time I have grown this, I enjoyed it for about 2 years and then it died.

Pinguicula lignicola--A delicate Cuban species that, like P. casabitoana, is a true epiphyte and lives on the vertical surfaces of trees (including Pinus sp.) and shrubs.

Pinguicula jarmilae--Reported from the Andes, with small flowers but relatively large leaves. The species description describes them as "stoloniferous", which if true is unique for this section. Unfortunately, nothing in the rest of the paper adds any details.

A subsequent paper has described a species called Pinguicula chuquisacensis. This plant is the same as Pinguicula jarmilae, but it is not clear which name should be used. The question is whether or not the P. jarmilae paper was in a journal of sufficiently large distribution so that the name is considered adequately published. The type specimen for this publication may also be missing. Until the dust settles on this argument, I will continue to use the name P. jarmilae.

Pinguicula pumila--This is the only species mentioned on this page that strays out of the Caribbean or South America. It occurs on mainland USA, all the way up to North Carolina.
