“…While describing the species, they compared its characters with those of T. sivaganganum, a distant species. Sivadasan and Nicolson (1982) provided illustrations of spadices of T. sivaganganum and T. fischeri ( Fig. 2A & 2B, respectively of their article), and illustration of spadix of T. manickamii is reminiscent of that of the latter species.…”

“…In the revision of the genus, Sivadasan and Nicolson (1982) provided a detailed account of the taxonomic history and stated that misidentifications have been frequent and mainly centered around Rheede's (1692) Rheede's Nir-tsjembu (1692: 11: 33, t. 16) and Nelenschena minor (1692: 11: 33, t. 17) represent the first Pre-Linnean printed records of Theriophonum; both are identified as T. infaustum N. E. Br. (1880) (Sivadasan and Nicolson, 1982;Suresh et al, 1983). The works of Schott (1860) and Engler (1879Engler ( , 1920 are significant in recognition and delimitation of the species described until then.…”

The genus Theriophonum (Araceae), represented by seasonally dormant tuberous perennials is endemic to India and Sri Lanka. Critical taxonomic appraisal of the constituent species supports existence of only five species, viz. T. dalzellii, T. fischeri, T. infaustum, T. minutum and T. sivaganganum, and all are with restricted distribution in India. Theriophonum minutum is the only species with extended distribution in Sri Lanka. The recently described T. danielii and T. manickamii are considered here as conspecific with T. infaustum and T. fischeri, respectively.

With in excess of 70 species, the Southeast Asian/Australian genus Typhonium is the largest genus of the Areae, a tribe that includes up to nine smaller genera of which Sauromatum and Lazarum have recently been reduced to the synonymy of Typhonium. To test the circumscription and relationships of Typhonium to the other Areae, we used chloroplast and nuclear DNA sequences (4319 aligned nucleotides) for 86 of the total 153 species, including representatives of all relevant genera. In the resulting phylogeny, Typhonium species fall into three well-supported clades: the first comprises most Typhonium species, including the type, T. trilobatum ; the second consists of the type of Sauromatum, S. guttatum, and other species formerly placed in that genus; the third includes only Australian endemics. Each of the remaining six genera of Areae is monophyletic. Sauromatum and Typhonium are not sister groups, requiring the recognition of Sauromatum. The Australian clade also needs to be ranked as a genus to achieve similar levels of morphological, geographic, and genetic distinctness among the genera of Areae. However, since only 10 of the 16 described Australian endemics currently placed in Typhonium have so far been sequenced, not including the type of the name of the Australian genus Lazarum, we refrain from applying this name to the Australian clade. Among the nomenclatural and taxonomic results of this study are a key to the nine species of Sauromatum, and five new combinations. We also report two new chromosome counts and discuss the implications of the molecular phylogeny for the evolution of Sauromatum karyotypes.

A new Australian genus of Araceae, with notes on generic limits and biogeography of the Areae

HAY, A., 1992. A new Australian genus of Araceae, with notes on generic limits and biogeography of the Areae. A monotypic aroid genus is described from Melville Island, Northern Territory, Australia. The genus is diagnosed in the tribe Areae by its tubular spathe base divided into two chambers by an annular septum. The genus is most closely related to Sauromatum and to some Asiatic, not Australian, species of Typhonium. It is proposed that the geography of the Areae (including Arum, Dracunculus etc.) may now suggest a Gondwanan (rather than Laurasian) and hence Cretaceous (rather than much more recent) origin for the tribe, and its dual arrival in Malesia.
