Taxonomic notes on southern Indian Portulaca (Portulacaceae)
The Indian species Portulaca suffruticosa has been confused with other taxa by many previous authors, due to lack of field collections and a paucity of specimens in Indian herbaria. Following a morphological taxonomic study supported by new field collections, P. suffruticosa is confirmed as an accepted species endemic to southern India and Sri Lanka, and as distinct from P. pilosa and P. tuberosa. The more recently described species P. lakshminarasimhaniana and P. laljii are considered to be conspecific with P. suffruticosa, and P. badamica conspecific with P. tuberosa; their names are accordingly synonymised. Lectotypifications of the names P. suffruticosa Wight, P. tuberosa Roxb. and P. wightiana Wall. ex Wight & Arn. were found to be necessary to avoid future misapplication of names and full descriptions of these three species are provided. A key to all Indian species of Portulaca is provided.
