100 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. 



the work is immensely enhanced by the dissections of the flowers and 

 leaves, and the vignette engravings from photographs, which are given 

 to show (without any addition of the artistic imagination) the actual 

 and natural habit of each species. The descriptions and historical 

 matter are mostly done by Miss Woolward, but not an inconsiderable 

 amount of valuable and interesting information is also contributed by 

 Mr. F. C. Lehmann, German Consul of the Colombian Republic, 

 whose experience in the orchidic regions of Central and South 

 America entitles him to a high place as an authority. Drawings of 

 species entirely unknown in this country, or, if so, only as dried 

 specimens, are promised by Mr. Lehmann, and will be published in 

 the later parts of the monograph, with names and descriptions, 

 particulars as to geographical distribution, and accompanied by a map, 

 as well as by notes on the temperature and elevation of the locality in 

 which he has discovered the plants. There are somewhat more than 

 a hundred species of Masdevallia known, and it is to be hoped that in 

 addition to the forty species already described, the Marquis of 

 Lothian will continue his magnificent work until it embraces them all.
