摘要

Morphological and cytological observations were carried out on Lindsaea trichomanoides (Lindsaeaceae), a fern species from New Zealand. The frond buds were used for mitotic chromosome observation. A chromosome number 2n = 76 is newly recorded in the genus. The basic number x = 38 is a new count for the Lindsaeaceae as well. About 150 species of Lindsaea are distributed in tropical and warm temperate regions of the world. It is a large but poorly understood genus. The taxonomic characters are generally not distinct and chromosome numbers of Lindsaeoid ferns are known only for a few species. Moreover, some of these chromosome counts are only approximate, and in some cases the identification of the material sampled is uncertain (Kramer 1971). Kramer (1971), and Love et al. (1977) enumerated all of the available cytological data for Lindsaea, where only about twenty species were recorded. The basic chromosome numbers counted were 34, 42, 43, 44, 47, and ca. 50; as a result, the ploidy of some polyploidplants cannot yet be determined in this genus.
