Trisetella hirtzii

Like all the Trisetellas, this is a very small plant, only 3 cm tall, and the flowers, too, are typical of the genus both in color and with their odd little tails.  The flowers are 1 cm and the plants blooms prolifically during the winter.  It is from Ecuador and named after a well-known orchidist.  It is related to Masdevallia, and like them prefers cool temperatures and good humidity.

Masdevallia strobelii

This is one of my favorite Masdevallias.  Masdevallia strobelii is small species from Ecuador in the section Saltatrices, with the typical hair-lined tubular and colorful flowers of that section.  It is intensely fragrant, blooms prolifically, has brightly colored flowers and is easy to grow, everything that could be asked.  Mine is grown in a plastic net pot in live sphagnum and always blooms several times a year.

Dendrobium alaticaulinum

Dendrobium alaticaulinum is a New Guinea Dendrobium from the Calyptrochilus section of that genus, though most of the New Guinea Dendrobiums I grow are from the Oxyglossum section.  The Calyptrochilus Dendrobiums tend to be large plants with long semi-pendant canes, but this species is very small in comparison, the canes around 15 cm.  The 2 cm flowers bloom at the end of the canes in clusters and do not open very widely.  The plant is not a very eager bloomer for me, but since I reduced the light a bit it has bloomed more freely, this the best blooming yet.

Dendrobium oreodoxa x cuthbertsonii

I purchased this hybrid several years ago and as far as I know it is still unnamed.  It is a hybrid of the micro-miniature Dendrobium cuthbertsonii from section Oxyglossum and the much larger cane-type Dendrobium oreodoxa from section Calyptrochilus, both species from New Guinea.  The hybrid seems little influenced by the Dendrobium oreodoxa parent.  Both plant and flowers look like the other parent, Dendrobium cuthbertsonii.  The individual growths are less than 3 cm and the flowers are nearly 4 cm long.

Masdevallia herradurae

Masdevallia herradurae or Acinopetala herradurae is a small, floriferous species from Colombia and Ecuador.  The plant is under 10 cm and the flowers are 2-3 cm.  When the plant is in bloom the flowers look like a clouds of dark insects hovering around the plant.  My plant is grown in a plastic net pot in live sphagnum.

Dendrobium cuthbertsonii bicolor

This is another one of my Dendrobium cuthbertsonii, the same species as the orange-flowered plant I posted not long ago, but this, obviously, is an entirely different color and is in fact a bicolored cultivar.  Like other plants of the species the flowers are veyr large for the size of the plant and last six to eight months.  The plant, some of which can be seen in the photos, is less than 3 cm tall and the flowers are 4-5 cm.  Some of my plants I grow in pots but this mounted on a piece of cedar shingle.
