GENERIC LIMITS IN GENTIANA (GENTIANACEAE) AND RELATED GENERA IN PAKISTAN AND ADJOINING AREAS ALONGWITH A NEW GENUS KURRAMIANA

Abstract

The genus Gentiana L. (s.l.) IS a heteromorphic assemblage. A synthetic approach is adopted to (reat Gentiana L. (s.l.) from Pakistan and adjoining areas by utilizing the data from palynology, seed morphology and chemistry. Nine genera viz„ Cbninalis Adans., Gentianodes Love & Löve, Qaisera Omer, Aliopsis Omer & Qalser, Gentianopsis Ma, Aloitis Raftn., C01nast0'na Toyok., Jaeschkea Kurz and a new genus Kun•cuniana Omer & Qaiser have been recognized. Gentiana L. (s.str.) and Genaanella Moench (s.stT.) do not occur in Pakistan and adjoining areas. The generic limits and their affinities of all the taxa have been discussed. A new genus Kun•cuniana Omer & Qaiser IS described, and compared in detail with other related crenera. The numerical analysis suooests its affinities with the genus Jaeschkea Kurz.
