HI, Y'All,

I asked for help on this last year, but never got any explanation from anyone WHY the stems of this Cactus just randomly decide to get skinny and "woody" and grow these ugly, dry-looking air-roots for NO reason???? It can be growing along with the normal, green ric-rac leaves and then--the tip just starts growing skinny and making all these roots. SOMEONE must have an explanation!!!

I take them outside for the summer where they grow well, but will also do the same thing. Inside, i can see how the lower light may cause this, but it seems so random. Years and years ago, when I got the original cutting from an old lady, it was a 4" piece of this skinny "leaf". However, from the skinny will grow the regular leaf, and a regular leaf will also produce some wide, some skinny.

Here's a picture of most of the plant.
