Two More Colombian IDs

[Pitter]

The first two images are of a ground growing orchid I purchased from a greenhouse. It doesn´t care for my cool climate but is plugging along. In warmer climbs it seems to be quite hardy and is used in landscaping in shopping centers here.





The second is a wild orchid growing near my house (2100m, Western Cordillera, Colombia).

Sobralia - not sure which
Odontoglossum or Oncidium - a bit hard to tell from the unopened flower.

the first one is Arundina graminifolia.
the second one is an Oncidium, possibly Oncidium sphacelatum

Thank you. I see that Arundina graminifolia is an Asian species.

Other images of Oncidium sphacelatum certainly look like my plant. In a brief look on google I didn´t see Colombia mentioned but it is stated to be in Venzuela close by.
