>Was Leo growing any Heliamphora or Darlingtonia? I think I remember reading

He had one plant which was doing only so-so since it was getting over
a chemical treatment for bugs.

>>Saw the dentate form of Dionaea. Interesting. He says it breeds true.
>Ummmm, what is dentate?

The marginal spines on the traps were reduced to only a mm or so long, each
triangular shaped. Gave the margin a saw-toothed appearance.

Several weeks ago I got some clumps of suspended aquatic Utrics to grow
(kill, more likely), including U. inflata, radiata, and "vulgaris." (Not
too sure on the ID of that last one yet). Through my own foolishness I let
the water table go down a bit on them, so they were thinking about drying out
(oops!). Well I rescued them and found that, as reported in the literature,
in response to conditions of drought U. inflata produces tubers. It does
this by increasing the internode distance between leaves on the stolon,
and decreasing successive leaf size, until the stolon tapers to a single
tendril. This tendril elongates to about 4+ cm and produces what seems to
be an amorphous lump of tissue at the distal end. This tuber is only
about 1.5 mm long and is white.

Hmm.

P.S. Also noticed that my Cephalotus is now producing flowers with
6 sepals, 12 anthers (as opposed to original 7 and 14)
