Notoleptopus is a monotypic genus of flowering plants in the family Phyllanthaceae. It is one of eight genera in the tribe Poranthereae. The sole species is Notoleptopus decaisnei. It is a monoecious shrub, native to Australia, New Guinea, and Indonesia.

Notoleptopus decaisnei had long been treated as a species of Leptopus, but in 2007, a molecular phylogenetic study of DNA sequences found it to be sister to a clade consisting of Pseudophyllanthus and Poranthera.[1] In 2008, the new genus Notoleptopus was created for it.[2]

The species, N. decaisnei, has eleven synonyms,[3] and was first described as Andrachne decaisnei by George Bentham in 1873.[4][5] The species epithet honours Joseph Decaisne.

  • Andrachne decaisnei Benth.
  • Andrachne decaisnei var. orbicularis Benth.
  • Andrachne fruticosa Decne. ex Müll.Arg.

Description

Bentham describes the species Andrachne Decaisnei as follows:

Apparently annual, but the stems hard and woody-looking at the base, much branched, decumbent, attaining 1 to 2 or even 3 ft., the whole plant softly villous. Leaves broadly obovate or obovate-oblong, ½ to ¾ in. long, on rather long petioles. Male flowers 2 or 3 together on very short pedicels. Calyx-segments 5, lanceolate, acute, spreading, about ½ line long. Petals narrow, nearly as long as the calyx. Female flowers solitary in the same axils as the males, on pedicels attaining 1 line when in fruit. Calyx-segments under the fruit broadly ovate, fully 1 line long, the base of the calyx contracted into a distinct stipes. Styles divided to the base into 2 branches. Capsule depressed, orbicular, villous, about 2 lines diameter.[5]

In Australia, it is found in Western Australia, the Northern Territory and Queensland.[3] In Queensland, under the Nature Conservation Act 1992, it is declared a species of "least concern".[6]
