The trumpet form of the lip is character istic of many of the most beautiful South American Orchids, as Sobralia, Lselia, Cattleya, etc. In other genera the labellum is variously modified. Sometimes it is small and petal-like, sometimes greatly expanded, forming the most conspicuous part of the flower (0»- cidium tigritntm ,OiloHtoijIossuin Londeshoniuijhianum).. In other instances it is almost indescribably transformed (Stanhopea, Gongora). In nearly all cases the labellum is provided with raised lines, crests, and markings (or guiding the insects. In many genera the is produced into a sac or spur, which secretes honey, or whose walls contain juices which are sought by insects. In the curious Madagascar Orchid, Angrwctim sesquipedale, the .spur attains the astonishing length of 10 or 11 inches (Fig. 1564). T}\e hahit of Orchid plants is almost as varied as that of the flowers themselves. It is dependent upon the mode of life of the plants, which, in this respect, may be divided into three classes, âsaprophytes, epiphytes, and terrestrial Orchids. True parasites are not known to occur in this family. The saprophytic Orchids are the most reduced forms, devoid of chlorophyll, and depending for their carbon food upon the organic matter of the humus in which they grow. The subterranean stem or rhizome consists of a much-knotted coral-like mass which takes the place of roots.
