Here is another attempt to get decent pictures of the teensy Lepanthopsis astrophora 'Stalky'. Aperture bracketing amongst other settings and a tripod! Bloom size is about 2 to 2.5 mm.
Ivy, most of the Ang distichum plants are sold as very tiny pieces, 2 - 3 inches long ( which is how this one started out). I would just make sure the pieces are shiny and clean and have some decent roots.
What I found on ebay is the following information.
shermantp in Larsen Wiscosin, $15.75 plus $5.95 shipping mounted on a grapevine and
incredibleorchids in Seattle Washington $9.99 plus $7.95 shipping in a 2.5" pot.
