 8 or 10, rising from the outer base of an hypogynous disk. Ovary of 4 or 5 free or 

 united 2-ovuled carpels, separating when ripe into as many 1-seeded 2-valved cocci, 

 (p. 84.) 



15. Meliaceae. Calyx small, 4- or 5-lobed, imbricate. Petals 4 or 5, linear, 

 usually valvate and.adnate at the base with the staminal tube. Stamens united into 

 a thick tube, usually inserted below an annular or tubular disk. Ovary 3-5-celled. — 

 Trees. Leaves exstipulate, compound, (p. 86.) 



16. Olacineae. Calyx small, 4- or 5-lobed. Petals 4 or 5, free or connate,

 trees. Leaves alternate, exstipulate. (p. 87.) 



17. Gelastrineae. Calyx small, imbricate. Petals 4-5, sub-perigynous, spread- 

 ing, imbricate. Stamens 4-5, inserted at the outer base of the disk; filaments subu- 

 late. — Shrubs or trees. Leaves usually alternate, stipulate, (p. 88.) 



18. Stackhousieae. Calyx 5-lobed. Petals 5, linear, erect, free or connate 

 above the base. Stamens 5, 2 shorter. Ovary 2-5-celled. Fruit of 2-5 globose 

 cocci. — Herbs. Leaves alternate, small, quite entire. Mowers small, greenish, race- 

 mose, (p. 89.) 



19. Rhamneae. Calyx superior or inferior, 4- or 5-lobed. Petals 4 or 5, 

 minute or 0. Stamens inserted on the edges of a disk, as many as the petals'"and 

 opposite them, small, incurved. Ovary 8-celled ; style 1 ; ovule in each cell 1, erect. 

 Fruit of 3 cocci. — Shrubs or trees, with often stellate down. Leaves alternate, rarely 

 opposite, stipulate, or 0. Flowers small, (p. 90.) 



* Ampelideae. Calyx small ; lobes imbricate. Petals valvate, caducous. 

 Stamens inserted outside the disk and opposite to the petals. Ovary free. — Shrubs, 

 usually climbers. Leaves simple or compound, stipulate or not. (p. 93.) 



20. Sapindaceae. Calyx 2-5-sepalled. Petals in the New Zealand species. 

 Stamens 5-8, hypogynous or inserted within a disk. Ovary 2- or 3-celled ; style 1 ; 

 ovules 1 or 2 in each cell, pendulous. — Trees. Leaves exstipulate, simple or com- 

 pound. Flowers racemose, (p. 94.) 



21. Anacardiaceae. Calyx 3-7-lobed. Petals 5, imbricate. Stamens 5, 

 inserted at the base of a lobed disk. Ovary 1-celled; style 1; ovule 1, erect or 

 pendulous. — Shrubs or trees. Leaves usually alternate, exstipulate. Flowers usually 

 small and panioled. (p. 96.) 



22. Ooriarieae. Sepals 5. Petals 5, free, becoming fleshy after flowering. 

 Stamens 10, hypogynous, all free, or 5 with the filaments adnate to the petals. 

 Carpels 5-10, 1-celled, 1-ovuled, whorled round a fleshy disk ; styles 5-10. Fruit of 

 dry achenes enclosed in the fleshy petals. — Shrubs or herbs. Leaves opposite, 

 exstipulate. Flowers racemose, (p. 97.) 



This order is a very anomalous one, whose affinities have never yet been discovered. 



Subclass III. Calyciflorae. Flowers with both calyx and corolla. Petals 

 usually free, and stamens inserted on the tube of the calyx or top of the ovary, which 

 is often inferior. 



Exceptions : Perianth apparently absent in some Halorayeae. 



Petals absent in Meryta, Fuchsia, Tetragonia, and some Halorageae. Petals united at the 

 base in Acaena, obscurely in Tillaea, united into a tubular corolla in some Loranthi. 



Stamens hypogynous in some Droserae and Tillaeae.
