Photos              Orchids


There are six distinct groups of orchids found in Vietnam. On the right, I have found some typical photos, showing the subfamilies characteristic.

The first group is the subfamily of Apostasioideae. It only have two genera with 15 species. In lack of other vascular name, I will call the "palm leaved-like". The inflorescent bears medium sized flowers, which can be more or less scatted. They are mainly terrestrial.

Second group contains the subfamily of Cypripedioideae, known as the "Lady's slipper orchids". Of its five genera with 120 species, only Paphiopedilum is found in Vietnam. Single, large flowers. Those orchids are in general epiphytic.

Third group is made of the subfamily of Spiranthoideae, which counts 95 genera with around 550 species. 18 of these genera can be found in Vietnam. Tiny flowers on a open, erect stalk. They are mainly terrestrial.

Forth group counts the numerous genera of the subfamily Orchidoideae known as the "Orchidoid orchids". They are mostly terrestrials with tubers or fleshy rhizomes. Medium size flowers sits on a rather open, erect inflorescent. They are mainly terrestrial too.

Fifth group is the huge subfamily of Epidendroideae. 576 genera with over 15,000 species. In Vietnam, four sub-groups are found: The primitive tribes (Lower Epidendroids), Epidendroid,  Dendrobioid and finaly Cymbidioid. In total, 60 genra can be found in Vietnam. A common characteristic is the more or less visible pseudubulbs. The flowers are rather large, sitting singularly on the stalks. They are mainly epiphytic, but there are a few terrestrial.

Sixth and last group holds the subfamily Vandoideae.  There are about 300 genera and 5000 species. Of these, 53 genera are present in Vietnam. The are easily recognised by their "fish-bone" structure. The flowers are relatively large, sitting in small till large groups.
