and Estrella de Cartago, Mr. Lankester was of the opin- 
ion that two species might be represented and he empha- 
sized a difference between the flowers: those from the 
type-locality being without the hyaline area on the sepals 
that is noticeable in the flowers of the plants from the 
higher altitude. Structurally the flowers of all the speci- 
mens examined are similar. There does not seem to be 
any specific difference dependent on altitude.
