What is the difference between a terrestrial and an epiphytic orchid?

TERRESTRIAL ORCHID MEANS THOSE WHO GROW ON LAND AND EPIPHYTIC ORCHID MEANS THOSE WHO GROW ON STEM OF TREES.

What is the difference between a terrestrial and an epiphytic orchid?
A list of all the types of orchids that exist.



Encyclia cochleata (L.) Lemée var. cochleata



National flower of Belize. Rather common epiphytic orchid. and one of the few Belizean orchids that flowers nearly year round. Distribution: Co, OW, Be, Cy, SC, To.



Bletia purpurea (Lam.) DC.



Terrestrial orchid. Common in savanna habitats. Flowers irregularly and can be found flowering nearly at any time of the year. Distribution: OW, Be, Cy, To.



Bletia purpurea

Catesetum integerrimum





Catasetum integerrimum Hook.



Very common epiphytic orchid. Often growing in dead stumps. The root mass is pointing upwards and acts as a trap for organic material. Male and female flowers differ (here female flowers). The flowers attract large numbers of huge bees (Eulaema meriana:Apidae: Euglossini). These bees are rarely seen at any other flower. Distribution: OW, Be, Cy, SC, To.



Encyclia radiata (Lindl.) Dressler



This is a relatively uncommon species. Flowers intermittently. Distribution Cy, SC.



Encyclia radiata

Epidendrum ibaguense





Epidendrum ibaguense Humb., Bonpl. %26amp; Kunth



This terrestrial orchid that is so common in much of Central America is very rare in Belize. I know it only from the higher reaches of the Mountain Pine Ridge (Cy) and from Victoria peak (SC). In the latter place it is very common.



Isochilus carnosiflorus Lindl.



Clumping epiphytic species. Flowers small. Common. Distribution: Co, OW, Be, Cy, SC, To.



Isochilus carnosiflorus

Lycaste aromatica





Lycaste aromatica (Graham ex Hook.) Lindl.



Epiphytic species with Large pseudobulbs. Uncommon. Mostly found along rivers. Distribution: Cy, To.



Maxillaria hedwigae Hamer %26amp; Dodson.



Smaller epiphytic species. Rare. Distribution: Cy.



Maxillaria rufescens

Mormolica ringens





Mormolyca ringens (Lindl.) Schltr.



Epiphytic orchid. Forms large clumps. Common. distribution: Cy, SC, To.







Myrmecophila tibicinis (Bateman) Rolfe



Very large orchid with huge pseudobulbs (which are filled with ants). Locally called "cow horn orchid". Mostly found along the coast and in savanna habitats. Flowers in the dry season. Common. Distribution: Co, OW, Be, Cy, Sc, To.



Myrmecophila tibicinis

Oeceoclades maculata





Oeceoclades maculata (Lindl.) Lindl.



This terrestrial orchid with attractive maculated leaves is a recent immigrant from Africa. I found the first two plants on the Green Hills Butterfly Ranch property in 1994. Now, less than a decade later there are thousands. I have found it in OW, Cy and To, but probably more widespread by now.



Oncidium altissimum (Jacq.) Sw.



Epiphytic orchid from humid forests. Common. Distribution: Co, OW, Be, Cy, Sc, To.



Oncidium altissimum

Oncidium sphacelatum





Oncidium sphacelatum Lindl.



"Golden Shower". Common epiphytic orchid forming large clumps. The masses of golden yellow flowers in the dry season are very attractive. Distribution: Co, OW, Be, Cy, Sc, To.



Sobralia macrantha Lindl.



Large terrestrial orchid. People often dig these plants out but they don't transplant very well and the individual flowers last only one or two days. Best to be enjoyed in its natural habitat. Distribution: Very local; Be, Cy.



Sobralia macrantha

Trigonium egertonianum





Trigonidium egertonianum Bateman ex Lindl.



Dragons mouth orchid. Epiphytic species. Common. Distribution: Co, OW, Be, Cy, Sc, To.



Notylia barkeri Lindl.



This small orchid is common and often found in old citrus plantations. The many small flowers are arranged in a pendant, cylindrical raceme. The flowers are slightly fragrant. Flowers mostly early in the year. But can be found flowering anywhere from January through September. Distribution: Co, OW, Be, Cy, SC, To.







Notylia barkeri

Vanilla planifolia





Vanilla planifolia Jacks.



This orchid is the original source of "Vanilla". Now cultivated in the old world for this purpose. This is a very unusual epiphytic species that is actually a vine. The plant flowers during the dry season but the flowers are rarely seen because they are high up in the trees. Fairly common. Distribution: OW, Be, Cy, Sc, To.
Reply:Terra = earth, Epiphite = parasitic - requires host plant.
Reply:terrestrial grows in soil..epiphytic doesn't need soil, usually grows in trees
