Phytochemical and Palynological Study of Forsstroemia remotifolia, Homalia besseri ‎and Pseudoleskeella catenulata in North of Iran

Mosses are small, non-vascular and non-flowering plants. Forsstroemia remotifolia was previously belonging to Leskeaceae family and its old name is Pseudoleskeella laxiramea (Schiffn.) Broth. According to recent morphological researches, changed from Leskeaceae family to the Neckeraceae family. Therefore, in present study, to eliminate the ambiguities in classification of this species, phytochemical and palynological investigation in F. remotifolia, Homalia besseri, and P. catenulata seems necessary. The results of gas chromatography (GC/MS) are showed that, F. remotifolia has 21 different types of fatty acids, H. besseri contains 23 types and P. catenulata possesses 18 types. Analysis of fatty acids has been shown 61.53% similarity in fatty acid compounds between F. remotifolia, and P. catenulata. Results of palynology showed that spore shape in populations of F. remotifolia is spheroidal and spore shape in populations of H. besseri is oblate, but the spore shape in population of H. b. A belonging to H. besseri is prolate and also the spore shape in population of P. c. Do. belonging to P. catenulata is spheroidal. Overall results of chemotaxonomy and palynology indicate close relationship between F. remotifolia, and P. catenulata.
