> _Pinguicula_
> Carroll's media (ICPN v11 n4 12/82 pp. 93-96)
> Murashige-Skoog media diluted 1:5, sucrose 20g/L
The first can be recommended for ALL _Pinguicula_ species tested so far
(ca. 30 spp. of different subgenera and sections).
> Terrestrial _Utricularia_
> Carrol's media
I can recommend this media ONLY for the large-leaved species _U.alpina_,
_U.longifolia_, and _U.calycifida_.

DO NOT USE CARROLL's MEDIA FOR _Utricularia_ sect.Pleiochasia!
IT WILL ALMOST CERTAINLY KILL YOUR PLANTS (at least young seedlings) RAPIDLY.
It did so for me with several species 8-(
I haven't yet any solution to the problems concerning these, some other
terrestrial species, and most _Genliseae_. _G.pygmaea_ seems to be very
tolerant, _G.violacea_ grows and flowers (!!) in 1/5 MS media (J.Nerz,
pers. comm.).
> Aquatic _Utricularia_
> Carroll's media (no agar)
> Pringsheim & Pringsheim media
The latter being the better one. The reference is:
Amer.J.Bot.49:898-901 (1962). Addition of sucrose may be helpful (the
original formula doesn't contain sucrose).
Kind regards and happy growing!
