THE .ORCHID REVIEW. 73 
A GROUP OF DENDROBIUMS, 
DENDROBIUMS are among the most popular of our winter and _ spring- 
flowering Orchids, and just now are making a grand display in collections. 
Among the species, Dendrobium nobile occupies the foremost place, and so 
extensively has it been intercrossed with allied species that its hybrids are 
also becoming a very numerous group, and they fortunately retain the free- 
growing habit and floriferousness of the parent. Five forms of D. nobile 
are shown in the annexed group, together with one of its hybrids, the latter 
being represented both by wild and artificially raised forms.
