Aerangis biloba Grows outside until temperatures drop below 50 deg. F. Currently, it's in the dining room with an eastern exposure Joy Keyser
Bulbophyllum medusae Bulbophyllum medusae

Grows in greenhouse. The "threads" are the petals of many individual flowers. This plant grows on a mount, but seems to do better when the mount is horizontal, rather than hanging.

 

Bulbophyllum rothschildianum Bulbophyllum rothschildianum Grows in greenhouse Edie Gulrich
Cattleya maxima Cattleya maxima Grows in greenhouse. It would probably be OK outside, since this is the "highlands" variety of C. maxima (plant is more compact than the one that grows at lower elevations, and has somewhat darker flowers) However, the warmth and humidity of the greenhouse are clearly beneficial.  

Cycnoches barthiorum

Cycnoches barthiorum male

Grows in greenhouse. This species has very different male and female flowers. The same plant can bloom with flowers of different sexes in different years, occasionally on different inflorescences in the same year, or even on the same inflorescence. In 2009, it bloomed male, top image (close up). In 2008 it bloomed female, bottom image. Less light and perhaps less fertilzer seems to encourage male flowers. It is very important to keep these plants quite dry in the winter, when they lose their leaves. Watering can resume when the new growth is several inches long, with plentiful new roots.

Cymbidium tracyanum

Cymbidium tracyanum

Grows outside, in nearly full sun. It is fragrant. Also note the very fuzzy lip.

 

Dendrobium lawesii Dendrobium lawesii Grows in intermediate greenhouse. It blooms on leafless canes, so do not cut the canes unless they are shriveled and brown. Another color form. Peter T. Lin

Laelia gouldiana

Laelia gouldiana

This plant grows on a mount, in almost full sun, outside (coastal). It can grow in a pot, but tends to do better mounted. The flowers are beautifully crystalline in the bright sunlight. A problem with some of the Laelias that are grown mounted is a tendency of nearly-mature buds to blast. Harry Phillips of Andy's Orchids recommends that the buds NOT be protected from watering, since they contain sticky sugar. The water dissolves this and permits the buds to open, otherwise they may stay glued shut, causing that very disappointing bud drop.

 

Oncidium hyphaematicum Oncidium hyphaematicum Grows in greenhouse. It is very fragrant. The inflorescence is about 4' long, and this is a young plant! Here is a closer view of a flower.  
Trigonidium egertonianum Trigonidium ergertoniamum Grows in greenhouse. Its thin leaves should be protected from direct sun. Plant produces multiple inflorescences, each with one flower.
