Gyrostemoneje. {End!. Gen. p. 978 ; Meisner, Gen. p. 322). Trees or shrubs inhabiting New Hoi 

 land. Leaves alternate, entire, feather- veined, without stipules. <? Calyx 6-7-lobed. Corolla 0. 

 Stamens indefinite, distinct, with anthers bursting longitudinally. ? Calyx cup-shaped, 6-7-lobed. 

 Corolla 0. Carpels 00, collected round a flat central torus, 2-seeded, with suspended campylotropal 

 ovules. Fruit composed of several membranous cases, arranged in a ring. Seed with a strophiolato 

 hilum. Embryo hooked round mealy albumen, with linear incumbent cotyledons and a slender inferior 

 radicle. — Two genera and three species at present constitute this group, about whose relationship we 

 have at present no certain evidence. Because of their unisexual imperfect flowers, numerous consoli- 

 dated carpels, and suspended ovules, they are related to Spurgeworts, and especially to the genus Hura ; 

 but they cannot be referred to them if Endlicher's statement is correct, that the albumen is mealy and 

 the radicle inferior. Hooker and others station it in the Urtical Alliance, but its composite fruit, mealy 

 albumen, and inferior radicle, do not justify that opinion. Desfontaines and Endlicher regard it as a 

 form of the Mallow worts, but the separated sexes, free stamens, peculiar albumen, and apetalous flowers 

 are unfavourable to that supposition. Finally, Meisner after referring it to Lindenblooms,has come to the 

 conclusion that it ought to be associated with Phytolaccads ; and if the flowers were not unisexual this 

 opinion would have great weight : for it must be admitted that the plants under consideration have much 

 the structure of that Natural Order. Nevertheless it seems for the present most advisable to associate 

 Gyrostemonads with unisexual Orders, among which they may be looked upon as a passage to the Phyto- 

 laccads in the Chenopodal Alliance.
