 Of all tribes of plants, this is the most singular, the most fragrant, and the most difficult of culture. The 

 flowers are often remarkable for their grotesque configuration, which has been likened to heads and bodies of 

 animals, and for the strange character of their stems, which are sometimes attenuated into a degree of grace- 

 fulness scarcely equalled even among grasses, and sometimes contracted into a clumsy goutiness of figure 

 such as is known no where else. The species are found inhabiting the mountains and meadows of the cooler 

 parts of the globe, or adhering by their tortuous roots to the branches of the loftiest trees of the tropical 

 forest, to which their blossoms often lend a beauty not their own. Vulgarly, this last description of plants is 

 called parasitic ; they are, however, not so, deriving no support from the juices of the plants on which they 

 grow ; but, on the contrary, are epiphytes, merely adhering to other plants for support, and vegetatmg amidst 

 the rich black soil which collects at the foot of all trees growing in a hot humid climate. It is very singular, 

 that the pollen of these plants has no parallel, except among the very different and distinct order of 

 Asclepikdeas. The only medicinal properties of the order exist in the roots of some of the Orchises, from 

 which the nutritious substance called salop is prepared. The Vanilla of the shops is the pod of the 'genus 

 called Vanilla. From the boiled stems of some of the Brazilian species a tenacious glue is obtained, which 

 is employed in many useful purposes. Division and offsets.
