Orchidioides is a section of Utricularia. It contains Us. alpina, asplundii, endresii, praetermissa, quelchii, campbelliana, buntingiana, jamesoniana and unifolia. This group along with Iperua (reniformis, nephrophylla, geminiloba, nelumbifolia and humboldtii) and sometimes longifolia are commonly refered to as the "epiphytic" Utrics. This name is rather a misnomer as most all of them grow terrestrially to some extent. Some, like longifolia and reniformis, are almost exclusively terrestrial in habitiat. The epiphyte tag seems to have taken hold back in the Victorian days when some clones of alpina and endresii were cultivated alongside orchids in an epiphytic manner.
In cultivation the Iperua and Orchidioides groups prefer a more well drained, less wet media. I find that most all of them do well in live sphag, the exceptions being the smaller species which do fine in pine bark mulch or peat/sand if moisture level is monitored closely enough. I also find that these groups seem to prefer lower temps by and large though reniformis seems adaptible and some others with forms from lower elevetions can take higher temps.
