M. ionocharis, Reichb. f. in Gard. Chron. 1875, p. 388. 
The number of Wuasdevallie in cultivation increases yearly ; 
in 1830 but three species were known to science, and these 
only from books, drawings, and dried specimens; 36 are 
enumerated in the 5th volume of ‘ Walpers’ Annalen’, pub- 
lished in 1861, and the number is largely increased since 
then ; of all the known species, probably a third are grown 
in Europe, and known only by cultivated specimens. 
M. ionocharis is one of the smaller species of the genus, 
and is remarkable for the bright colouring of the flowers that 
areabundantly produced in autumn. It was made known by 
Dr. Reichenbach, who published it from specimens discovered 
by Mr. Davis in Peru, and flowered by Messrs. Veitch in the 
Royal Exotic Nurseries, to whom the Royal Gardens are 
indebted for the specimens here figured, which flowered in 
September, 1875.
