I found a nice site with pics of flowers in Thailand. Here are some for your enjoyment.
AERIDES
The name AERIDES means air-plant. About 20 species belong to this genus of monopodial epiphytes. Most species are easy to grow and have highly perfumed flowers. AERIDES ODORATA is variable in colour, from deep pink to pure white, and is widely distributed throughout Southeast Asia. AERIDES QUINQUEVULNERA is from Philippines and New Guinea. AERIDES ROSEA, from Northern Thailand, was formerly well known as AERIDES FIELDINGI. Many hydrids have been made between AERIDES and other members of what are loosely termed the "vandaceous" family.
ONCIDIUM
Among the 400 or so ONCIDIUM species are many extremely varied plants, which range from diminutive equitants - small, fan-like, foliage plants with brightly coloured flowers - to large-bulbed, long-spiked beauties such as ONCODIUM MACRANTHUM. In between, are numerous, delightful plants of modest size with brightly coloured blooms which are predominantly yellow.
Height : 15-30 cm (6-12in).
PHALAENOPSIS
the natural genus of PHALAENOPSIS is made up of almost 50 species, originating from the Old World through India, South-east Asia, Indonesia and parts of Australia. Most are evergreen epiphytic plants. Many hybrids have been produced from the wild species. It is arguably the most important commercial genus of orchids in the world.
Heigh : 15 cm (6in)
ADENIUM OBESUM (Desert Rose)
A member of the same botanical family as the Frangipani, it is, in fact, sometimes called the Japanese Frangipani. Adenium is a small treelet native to arid East Africa and Arabia, reaching a height of about 1 m. Intolerant of damp conditions, Adenium is usually seen grown as a pot plant in Southeast Asia.
When cut, exudes a poisonous latex.
I see these 'Desert Rose' flowering plants all around the area. Have some across from our house. Brilliant bright pink color... nearly fluorescent!
