Abstract

The genus Isachne includes grasses which are found particularly in wetlands. Most of the species included in the genus are either endemic or rare, one of the exception being Isachne globosa, which is found in almost all regions from where the other species have been reported. Their rarity and diminutive florets make it difficult for taxonomists to identify, collect, distinguish and microscopically study them. The most available grass I. globosa can be used as a representative species and is well flourished in regions where they grow. Also, it shows intraspecific variations, which again makes taxonomists hard to distinguish the species. Recently I. henryi reported in 1988 has been shown to be a variation of I. globosa. No taxonomic studies or revisions have been carried out in this genus so far. The present study targets review of the genus which also highlights observations of the present researchers. An extensive study of the genus is recommended to unwind the existing taxonomic ambiguities.
