Masdevallia medinae

Masdevallia medinae is from Ecuador and is a very small species, only 4-5 cm tall with flowers that are nearly as large, around 4cm.  I tis supposed to warm-growing, but I grow it cool-intermediate with all my other Masdevallias.  It is potted in live sphagnum and blooms in late fall or winter.

Barbosella cogniauxiana

A Brazilian species, this orchid is really tiny, growing as a mat of oval leaves that are only 1.5cm, with flower spikes of 5cm and single 3cm flowers.  The plant is temperature tolerant and easy to grow and can produce a mass of flowers that almost completely hide the plant itself.  It is best grown mounted, and my plant, rather recently acquired is glowing on a piece of a branch.  It is related to Pleurothallis and belongs to a small group of species from Central and South America.

Dracontia pachyglossa

Dracontia pachyglossa, also known as Pleurothallis paphyglossa, is a species from Mexico, Guatemala and Costa Rica.  My plant is 15cm tall with flower spikes equally long that come from the base of the leaf and bloom successively with four to five 2 cm flowers.  The plant is temperature tolerant and like most Pleurothallids prefers good humidity and air movement.

Stelis hirtella

These two tiny little Stelis are from Peru and Ecuador, at least if it is correctly identified.  I received the first species (with the purple-centered flowers) as an unidentified Stelis from Ecuador.  Someone has suggested that it is Stelis hirtella and and some of the pictures I've seen of that species match, though others do not.  The second plant, which does not have the purple centers, is also identified as Stelis hirtella, and is similar in plant size and form.  The plants are 3cm tall with 5-6cm flower spikes and 6mm flowers.  Perhaps someone who sees this posts is expert enough to sort these two out, but the Stelis species are notoriously difficult to distinguish.

Phragmipedium Cardinale 'Birchwood' AM/AOS

Phragmipedium Cardinale 'Birchwood' is an awarded clone of an older Phragmipedium hybrid.  It is a hybrid of Phragmipedium schlimii and Phragmipedium Sedenii.  The plant actually belongs to my son who won it at the last orchid society Christmas dinner.  It was in bloom at that time, but not doing very well, with a lot of dead leaves and black leaf tips.  We keep it in a saucer of water so that it is soaking wet at all times and grow it on a bathroom windowsill.  It has put up numerous new growths and the black leaf tips have stopped.  It has just started blooming and this is its first flower.

Dendrobium cuthbertsonii (three new plants)

I've posted many pictures of Dendrobiuum cuthbertsonii in the past.  These are photos of three new acquisitions, one a nice clear orange and the other two bicolors (somewhat hard to see on the third photo).  Dendrobium cuthbertsonii is a micro-miniature species from New Guinea with huge (for the size of the plant) and long-lasting flowers (six months or more).  The species is considered to be difficult, but with the right conditions is relatively easy to grow and flower.  It prefers cool temperatures, high light and constant moisture to do well.
