But few members of this family have any useful properties, but 

 the beauty of the flowers of very many species, delicious fragrance, and 

 gorgeous colouring of others has made them great favourites in culti- 

 vation, the epiphytal and tropical ones especially so Of the few- 

 having an economic value, the species of Vanilla are the best known, 

 the fruit capsules are carefully dried, and valued foi' their delicious 

 perfume, Angraecum fragrans is a native of Mauritius and Bourbon, 

 its leaves are strongly scented and have been used medicinally and for 

 scenting tea. Salep consists of the tubers of several species of Orchids, 

 natives of Europe and Asia Minor; these tubers contain a large quantity 

 of starch and were formerly used medicinally ; a decoction of them 

 properly prepared is said to be " one of the best articles of diet a con- 

 valescent can use." None of our indigenous species are of much 

 value ; the epiphytal ones are usually small flowered, and their flowers 

 white or yellow ; some of the terrestrial ones bear handsome flowers, 

 but their cultivation is difficult.
