Poranthera is a genus of flowering plant belonging to the family Phyllanthaceae first described as a genus in 1811. [3] [4]

It is one of eight genera in the tribe Poranthereae. [5] Its closest relative is Pseudophyllanthus .

Poranthera is native to Australia and New Zealand. [2] The name is derived from the Greek word, poros, "opening or pore", and the Latin word anthera, "anther". [3] [6]

Poranthera consists of monoecious or rarely, dioecious annual or perennial herbs. On the anthers, the line of dehiscence does not extend beyond the apex. It does not have the clearly round pores that define truly poricidal dehiscence. [5]

Poranthera alpina has been placed in the monospecific genus Oreoporanthera by some authors, but in 2007, a molecular phylogenetic analysis of matK and ITS sequences showed this species to be embedded in Poranthera. [7]

names in Poaceae [2]

In 1830, Rafinesque [8] used the name Poranthera to refer to a very different plant than that to which Rudge had already applied the name. Thus he created an illegitimate homonym. Species names coined using Rafinesque's homonym: [9] [10]

  1. Poranthera ciliata - Sorghastrum nutans
  2. Poranthera nutans - Sorghastrum nutans

Persoonia, commonly known as geebungs or snottygobbles, is a genus of about one hundred species of flowering plants in the family Proteaceae. Plants in the genus Persoonia are shrubs or small trees usually with smooth bark, simple leaves and usually yellow flowers arranged along a raceme, each flower with a leaf or scale leaf at the base. The fruit is a drupe.

<i>Kunzea</i> Genus of flowering plants

Kunzea is a genus of plants in the family Myrtaceae and is endemic to Australasia. They are shrubs, sometimes small trees and usually have small, crowded, rather aromatic leaves. The flowers are similar to those of plants in the genus Leptospermum but differ in having stamens that are longer than the petals. Most kunzeas are endemic to Western Australia but a few occur in eastern Australia and a few are found in New Zealand. The taxonomy of the genus is not settled and is complicated by the existence of a number of hybrids.

Philotheca is a genus of about fifty species of flowering plants in the family Rutaceae. Plants in this genus are shrubs with simple leaves arranged alternately along the stems, flowers that usually have five sepals, five petals and ten stamens that curve inwards over the ovary. All species are endemic to Australia and there are species in every state, but not the Northern Territory.

Ricinocarpos is a genus of evergreen flowering plants in the family Euphorbiaceae and is endemic to Australia. Plants in the genus Ricinocarpos are monoecious shrubs with leaves arranged alternately along the branches, the edges curved downwards or rolled under. Male flowers are arranged singly or in racemes at the ends of branchlets, with four to six sepals that are fused at the base. There are four to six petals that are longer than the sepals, with many stamens fused to form a central column. Female flowers are arranged singly and are similar to male flowers but with three styles fused at the base and with a deeply branched tip. The fruit is a capsule containing seeds with an elaiosome.
