"The Indian species, with the exception of P. Hookeriana and of a new species 
recently discovered in Burma, belong to the section Nervilia, in which the leaf and 
flowers are not contemporaneous. The species with contemporaneous leaf and flowers 
. are mostly natives of America, only one being Japanese, and two Indian.
