MASDEVALLIA GUTTULATA. 
presence of little tufts of stiff hairs scattered over the inner surface of the sepals, and 
having at first sight the appearance of small crimson spots. This characteristic I have 
endeavoured to show at fig. 1 of the accompanying Plate. 
Consul Lehmann, who appears to be almost the only collector of this species since 
its discovery by Wallis, gives the following information : 
The habitat of Masdevallia guttulata is in Ecuador, where it grows on trees in dense, very damp 
woods, at an elevation of 600 to 1,200 métres (1950 to 3,900 feet). The annual mean temperature of this 
region ranges between 21° and 25° Centigrade (about 69° to 77° Fahrenheit), and rain falls all the year 
round. The distribution of this species appears to be confined to one comparatively ‘small locality, the 
banks of the Rio Namora in the Eastern Andes of Loja.* I observed it here for the first time in 
November 1876, and subsequently on various other occasions. Near all the numerous rivers in the vicinity 
belonging to the same watershed, I have seen no trace of it, although I have found there four other distinct 
species of this section of the genus Masdevallia, three of which are still undescribed. M1. guttulata, though 
not a profusely flowering species, is constantly in bloom in a wild state, and even when cultivated at one 
of my orchid stations in Colombia, it is remarkable for this characteristic.
