which, we believe, is a universal favourite, for no person who is fortunate enough 
"0 See this grand old plant in flower, can fail to admire its beauty. The flowers

re Species, but all are worth growing; and they can be easily grown by everyone 
he has a cool greenhouse. The specimens that were exhibited at the Edinburgh 
how in 
si September last made a grand display. Our drawing was prepared from : 
H y ue example, grown in the fine collection of C. Walker, Esq., Brettarg 
a Milnthorpe, who has also many other rare and remarkable specimens of the 
ut classes of Orchids, which Mr. McGregor, the gardener, has been very 
— in cultivating, This interesting collection was removed a few years ago
