Pleurothallis palliolata grows in Costa Rica and Panama at altitudes of 3500 to 6500 feet. It is cool to warm growing and needs low light and can bloom just about any time of the year. It both blooms and grows keikis at the base of the leaf.
I have had a lot of success with this species in the past but it doesn't grow well any more as the base temperature in the greenhouse has been rising over the last couple of years.
Ceratostylis retisquama grows in the Philippines at lower elevations up to 1500 feet. It is warm to hot growing, needs bright light and can bloom any time of year.
This species can be grown in a wood slat basket or mounted on cork bark. I am going to use a basket for this because I have more bright light options and I don't know which direction the new growth will go.
Laelia pumila grows in Brazil at elevations from 1500 to 4000 feet in swampy forests. It is fragrant, needs a dry winter rest and blooms in fall. What I got was the Coerulea form, a cross of My Blue Heaven x Sanbar Ind so it should be very pretty.
I have had this species before and killed it by not cutting back on the water in the fall. All the roots died and it never recovered. This time I am going to mount it on cork and place it where it will be misted through the summer. That should make it easier to control the watering than potted as I had them before.
Sophronitella violacea grows in eastern Brazil in shady and humid mountain forests. It is cool to hot growing and blooms in spring.
This is a very small plant on a small piece of treefern. There are two pseudobulbs that have a leaf and four more that I think are live backbulbs. I am going attach the treefern to cork bark to try to avoid disturbing the roots.
