The monophyly of these genera was later supported in a 2003 phylogenetic study of the family. [6] In the Wettstein system , this family was the only one placed in the order Verticillatae. Likewise, in the Engler , Cronquist , and Kubitzki systems , the Casuarinaceae were the only family placed in the order Casuarinales.
Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

The genera Allocasuarina was created out of a grouping of plants formerly placed in Casuarina, because of subtle but consistent differences – Casuarina species have 6 to 20 scale-like teeth in each whorl of leaves, their samaras are grey or yellowish-brown, and the bracteoles of the fruiting cones are thin, woody and extend well beyond the ...
The genera Misophrice and Apion have also been recorded on Casuarina, but the nature of their associations is unknown. [13] Hemiptera: Casuarinicola jumping plant lice feed on sap of Casuarina. [15] Another hemipteran associated with this genus is the felt scale Choneochiton casuarinae (Eriococcidae). [16]
Allocasuarina verticillata, commonly known as drooping sheoak, [3] is a species of flowering plant in the family Casuarinaceae and is endemic to south-eastern Australia. It is a small dioecious tree that has drooping branchlets up to 400 mm (16 in) long, the leaves reduced to scales in whorls of nine to thirteen, the mature fruiting cones 20–50 mm (0.8–2 in) long containing winged seeds 7 ...
Allocasuarina littoralis, commonly known as black she-oak, [3] is a species of flowering plant in the family Casuarinaceae and is endemic to eastern Australia. It is dioecious, or less commonly a monoecious tree or shrub, that has its leaves reduced to scales, usually in whorls of six to eight, the mature fruiting cones 10–30 mm (0.4–1 in) long containing winged seeds 4.0–10 mm (0.2–0. ...
Allocasuarina huegeliana, commonly known as rock sheoak [3] is a species of flowering plant in the family Casuarinaceae and is endemic to Western Australia. It is a dioecious tree that has its leaves reduced to scales in whorls of eight to ten, the mature fruiting cones 14–35 mm (0.55–1.38 in) long containing winged seeds (samaras) 5–7 mm (0.20–0.28 in) long.
