ery numerous are the varieties of the beautiful Odontoglossum crispum , 
which is perhaps the most popular and useful Orchid in cultivation. 
They range from pure white through innumerable spotted forms to 
i mauve, with deeper coloured blotches, and in another direction even 
to light yellow. Most of the forms, however, exhibit spots of different shades of 
chestnut-brown, red, or mauve-purple, while in the one figured they are golden- 
yellow, thus affording a decided contrast to the ordinary kinds. It flowered in 
the collection of Baron Schroder, The Dell, Egham, some months ago, when 
the annexed plate was prepared. The yellow is confined to the sepals and lip, the 
petals being pure white. The spots vary from five to seven on each sepal, and 
are situated just below the middle. The dise of the lip is yellow, and immedia- 
tely in front of this is one large deep yellow blotch. It is a very élégant variety. 
“ The native home of Odontoglossum crispum , ” Write Messrs Veitch in their 
Manual of Orchidaceous Plants , “ is on the western branches and spurs of that 
portion of the eastern Cordillera which lies between lat. 3,45° and 5,50° N., 
a distance from north to south of about 180 miles, having the city of Bogota 
about midway between the northern and Southern limits. Its vertical range is 
7,500 to 8,800 feet élévation, a zone that in those régions is occupied by forests 
composed chiefly of cinchonaceous trees, walnuts, and evergreen oaks ( Quercus 
tolimensis). It is in the occasional openings of this forests, and especially along 
the numerous mountain streams, that O. crispum occuis, it grows chiefly on the
