Dendrochilum I have included my Dendrochilums on this site because, like Coelogynes, they are part of the higher level category, Coelogynae. This beautiful group of about 200 very quaint, small to miniature orchids come from the Philippines through to Borneo. They are sometimes known as necklace orchids because they have numerous small flowers on long pendulous 'strings'. There are some species that should be in every collection and probably on every kitchen window sill. Individually, the flowers are insignificant but when grown into a specimen size plant the impact is stunning. Much more information is available at dendrochilum.com

Pholidota This genus from the Coelogynae group comprises about 40 species from Asia, New Guinea, the Philippines and some Pacific islands. They are not as widely cultivated as many orchids and only a handful are available.

Pleione Pleiones are a very beautiful group of deciduous orchids sometimes known as window orchids because of European habits of growing them in window boxes. The spectacular flowers are enormous for the size of the plant. Their popularity is rising fast. I am struggling to hybridise these with Coelogyne to introduce the pinks and mauves. Some specialised Pleione websites are Kool Plants and Pleiones.

Only
Pleione formosana is in this collection at the moment but seed from some other species has been imported and I am experimenting in my lab to hold seed over for several months so that germination coincides with southern hemisphere conditions.

Bletia Bletia is another group of rare deciduous relatives with pink/mauve flowers from Columbia, Cuba and Jamaica. They have very small insignificant flowers in terms of showy displays. My one attempt at deflasking Bletia florida failed miserably and I have not been able to get more. Deflasking deciduous orchids is a challenge!
Chelonistele Chelonistele sulphurea, which is sometimes sold as Coelogyne ramosii, is a small to medium cool growing plant with small yellow flowers from Malaysia, Java and the Philippines. I do not have them in my collection so I am not covering them on this site at this stage.

Otochilus These small flowered orchids from east Himalayas to China and southward through Burma to Vietnam are sometimes known as Coelogyne fusca. David Banks has recently imported three species into Australia but these orchids are collectors items only at this stage. David also published a comprehensive article on these orchids in the November 2008 edition of The Australian Orchid Review.

Notes: The 270 named Dendrochilums are mainly small plants with tiny flowers densely populated along pendulous spikes. They often look insignificant until the plant is grown into a large specimen size and then the plant takes on an amazing attraction when in flower. Coming from mossy cloud forest areas they all require warm, humid growing conditions and are not suited to cool to cold areas unless cultivated under glass.

In cultivation, they should be grown with other small plants for two reasons. Firstly, because the plants are small they are generally grown in small pots. All orchids (or other plants) in small pots, dry out very quickly. If mixed with larger pots, the small pots will be too wet or the large pots will be too dry. Secondly, in a mixed pot size collection, it is incredibly easy to create 'rain shadows' where water is blocked off by large leaves, or, large leaves funnel and drain water onto a small pot causing water-logging.

Notes: These orchids are very closely related to Coelogynes and Dendrochilums. They tend to have pendulous flowers spikes with two rows of small flowers. Although not as popular as their cousins, they are very attractive and some are very easy to grow and flower prolifically. If they were more available for purchase in nurseries, their popularity would certainly be much higher.
    Pholidota are variable in native growth habit. They grow as epiphytes (on tree trunks), lithophytes (on rocks) or as terrestrials (on the soil in litter).
