Q: About Utricularia section Aranella

A: This Utricularia consists of a set of terrestrial species, all mostly in South America. They have been grouped into this section because they have similar traps, the upper corolla lips have an interesting little curve near the central base that forms a kind of pocket, and also the bracts and sometimes calyx lobes are usually ragged-edged to deeply fimbriate-lobed.

Utricularia blanchetii--This terrestrial species is particularly gratifying to grow because the flowers are exceptionally pretty, as they show a delicate range of blue to purple coloration. When they are not in flower, the extremely delicate foliage can be very easily lost---do not toss this plant unless you are sure it has died!

Utricularia fimbriata--Another easily grown terrestrial from this group. A good example of one of the yellow-flowered plants in the section.

Utricularia blanchetii
U. blanchetii
Utricularia simulans--This plant has a really remarkable range. Its Latin American range includes Cuba, Belize, Colombia, Venezuela, Guyana, Surinam, French Guiana, Brazil, Bolivia, and Paraguay, and it occurs in several counties in peninsular Florida. But what is really remarkable is that it ranges into Africa, too! Furthermore, Taylor notes that it has been reported to form tubers! I have looked for this plant a few times in Florida, but each time I arrived at a "sure site"I found instead only newly established golf courses.
