Cymbidium sinense

Cymbidium sinense (Jacks.) Willd., Sp. Pl. 4: 111 (1805).
Distribution: Assam to Nansei-shoto.

The plants are flowering after a recent forest fire which has consumed all the above ground parts. The underground roots are not affected by the fire and will sprout new plants.

This colony in northern Thailand is growing on the ridge of a sandstone mountain at elevation of 700 metres. The short Dipterocarp forest does not provide much shade. The well drained sandy soil gets rain during the monsoon only. The inflorescences are 30 cm tall (rather short) and carry 6 to 8 flowers (rather few). The flowers are 45 mm wide.

A description can be read on the link below.

Thanks for sharing Rik. We are really lucky to have someone on the spot to report on the situation that prevails in your area.

Do you know if the fire was started as part of a clearance project?

Your pictures clearly shows how amazing orchids are! The way they can survive sometimes puzzle me

Forest fires

If you look at the world map in the link below, you may wonder how many orchid plants are being consumed by fire. Even more tragic is the destruction or degradation of their habitat.

Causes and reasons for starting forest fires.
Slash and burn farmers all to often let their field fires run into the forest.
Cattle are herded on the paddy fields during the dry season and moved into the forest during the rainy season. The herders burn the forest to have new grass at the time of the change over.
Red or weaver ant egg collectors use fire to flame the biting owners of the eggs. The gatherers of wild honey use fire to create smoke.
Hunters use fire to drive animals out of the forest.

At present most forest fires have been extinguished by the rain and nature can rebound.
