dc.descriptionThe genus Lisianthus as construed by A. H. R. Grisebach in 1839 comprised five sections, as follows: Macrocarpaea, Choriophyllum,  Chelonanthus, Helia, and Calolisianthus. The same sectional treatment of the inclusive genus Lisianthus was maintained in his contribution to De Candolle's Prodromus (1845). Of the five sections recognized by Grisebach Macrocarpaea is the best defined morphologically:  it, as a genus, is the subject of a monographic revision soon to appear in the Contributions of the United States National herbarium. The disposition of the Peruvian Section Choriophyllum (monotypic) has not been determined, pending an examination of the type of Lisianthus loranthoides in England, but it is likely referable to Symbolanthus. Section Calolisianthus, when redefined in the light of present knowledge, has clear limits. Sections Helia and Chelonanthus have never been well defined. Almost completely transitional corolla forms exist among certain species of the two sections, yet there is a strong morphological divergence in the corolla type in this alliance, either toward an open ample tube, or a slender variously gibbous or constricted tube.en-US
