 mixture of loam, peat, and sand ; and cuttings taken from 

 ripened wood will root in sand under a hand-glass, in heat.

 gular, and irrepov, pteron, a wing ; fruit with unequal wings.) 



LIN. SYST. Decdndria, Digynia. Calyx 5-parted. Petals 5, 

 unguiculate, with roundish, fringed limbs, upper one largest. 

 Stamens 10. Anthers sagittate, obtuse. Styles 2, filiform. 

 Samarae 2, 1 -seeded, each ending in a wing at the apex, thickened 

 on the outer side. Shrubs with alternate leaves, by which it dif- 

 fers from all the rest of the genera in this order, and yellow 

 flowers.

 pand margins ; flowers in terminal spicate racemes. Tj . S. Na- 

 tive of Guinea. Flowers pale-yellow.

t A genus allied to Malpighiacece.

 pentapetala in Malabar). Lam. ill. t, 299. D. C. prod. 1. p. 



592. Samadera, Gaert. fruct. 2. p. 352. t. 156. Biporieia, Pet. 

 Th. gen. mad. p. 14. 



LIN. SYST. Octo-Decdndria, Monogynia. Calyx 4-5-parted, 

 permanent, with the 2 outer lobes glandular. Petals 4-5, ob- 

 tuse, much longer than the calyx. Stamens 8-10, free, hypo- 

 gynous, furnished with a scale at the base. Ovary turbinate, 4 

 or 5-lobed at the apex. Style 1, filiform, rising from between 

 the lobes. Capsules 4-5, or from abortion only 1-3, compressed, 

 1-celled, 1-seeded. Shrubs, with alternate leaves. Perhaps 

 this genus is allied to Banisteria or Balanopteris. But accord- 

 ing to Jussieu the fruit is referable to Ochnacece or Simarubaceee.

 octandrous. Tj . S. Native of Madagascar. Mauduita pen-

 pentandrous. Ij . S. Native of Malabar. Karin njotti, Rheed. 

 mal. 6, t. 18. Peduncles long, pendulous, nodding, umbellately 

 many-flowered. Perhaps only a variety of the preceding. Flowers 

 variegated. Fruit intensely bitter. 



Five-petalled Niota. Tree 36 feet. 



Cult. These trees will thrive well in a mixture of loam and 

 peat, and cuttings taken from ripened wood will root in sand 

 under a hand-glass, in heat.

Calyx 5, rarely 4-9-parted. Petals about the same number, 

 inserted round the hypogynous disk, alternating with the caly- 

 cine lobes, usually self-coloured, rarely wanting. Stamens in- 

 serted in the hypogynous disk, usually 8 in number, rarely 5-12; 

 anthers oblong. Ovary twin. Style 1. Stigmas 2. Fruit 

 constantly of 2 carpels (rarely 3), which are at length separable, 

 indehiscent, samara-like, 1-celled, 1-2-seeded, compressed, end- 

 ing at top in a membranous, diverging wing, which is thickened 

 on the outer side. Seeds oblong, fixed to the base of the cell. 

 Seed-cover rather fleshy. Albumen wanting. Embryo curved 

 or convolute, with leafy, irregularly-wrinkled cotyledons and 

 a roundish radicle, which is directed to the base of the cell. 

 Valuable timber-trees, with opposite, usually simple leaves, as 

 in Malpighiacece, rarely compound, as in Hippocastdnece and 

 Sapindacece. Flowers inconspicuous, racemose or corymbose, 

 axillary, usually dioecious or polygamous from abortion, and 

 sometimes without petals. All the species abound in saccharine 

 sap, from which sugar may be prepared. This order is truly 

 intermediate between the two preceding and the two following, 

 but is easily distinguished from them in the flowers being mo- 

 noecious, dioecious or polygamous, never hermaphrodite. 



Synopsis of the Genera.

 7-9, rarely 5. Leaves simple, usually lobed.
