Rhipsalis teres f. capilliformis

It's been a while since I've posted any Rhipsalis, partly I just haven't kept up with the all the name changes and will most likely come up with the wrong name.  We have a couple of old plants of this species, which we always knew as Rhipsalis capilliformis. My understanding is that it's now correctly referred to as R. teres f. capilliformis. We first saw one in the Conservatory at Golden Gate Park in San Francisco while on our honeymoon in 1967. We fell in love with it and have been growing them ever since.
