Information from CliniTox veterinary text.

Domestic Rabbit: No known toxic effects reported; mild temporary digestive upset may occur if large quantities are consumed

Pet Bird: No documented toxicity; small nibbles of the plant are considered safe for common pet bird species

Small Rodents (hamsters, guinea pigs, gerbils): No harmful effects reported from accidental ingestion of small amounts of the plant

Confusion Risk

The following plants look similar and may be confused:

Foxglove Digitalis purpurea

Foxglove has bright, bell-shaped flowers that may be confused with some colorful Masdevallia varieties; foxglove is highly toxic to all mammals, while Tailed Orchid is non-toxic. Key difference: foxglove grows as a tall terrestrial stalk, while Masdevallia is a small epiphytic orchid.

Yellow Lady's Slipper Cypripedium parviflorum

This wild orchid has unusual shaped flowers that can be confused with Masdevallia; it causes mild contact dermatitis and digestive irritation, while Tailed Orchid does not. Key difference: it has a distinctive slipper-shaped lip, while Masdevallia has a characteristic tailed sepal.
