Thi^ order is distinguished from Malpighiacea? in the presence of albumen, and in the petals being 

 furnished at the base with a scale; the habit of the plants is also different. Shrubs and trees, with simple 

 alternate leaves furnished with axillary stipulas. Native of South America, Mauritius, and Madagascar, and 

 one from India. Cuttings.

Undulated unguiculate spreading petals form one of the most obvious characters of this order, the species of 

 which are all tropical, and are either trees or shrubs, often climbers. Many of the Malpighias are well known 

 for the prurient hairs produced on the surface of their leaves ; their fruit is eatable, their timber of a deep red 

 color, and their bark a febrifuge. Their showy pink or yellow flowers, and firm neat foliage, render all this 

 order worthy of cultivation, except Aspicarpa, which is a weed. Cuttings.

Valuable trees, natives of the woods of Europe, Siberia, and North America. Their flowers are in all cases 

 inconspicuous ; the breadth and rich color of their leaves constituting their beauty. All the larger species 

 abound in a very saccharine sap, from which sugar is prepared in North America : it is chiefly made from 

 A y cer saccharlnum and Negimdium, but may be obtained from many others. Commonly by layers or seeds, 

 but all the species will grow by cuttings in sand.

 The order is much valued for the grandeur of the foliage and flowers of most of the species, which are 

 all hardy trees. Their bitter fruit has sometimes been used as a sternutatory ; it contains a large quantity of 

 potash, and an abundance of starch. The bark is astringent, bitter, and febrifugal, and has been recommended 

 as a substitute for Cinchona. Seeds or layers, and by grafting.

A Very distinct order closely allied to the Terebinth acese, but, from the hypogynous insertion of the petals 

 and stamina, and the structure of its fruit, differs essentially from that order. It agrees with Hippocastaneae 

 in the insertion of the petals and stamina, and in having opposite palmate leaves, but differs from it in having 

 a large radicle and small cotyledons, not with a small radicle and large cotyledons as in that order. The order 

 contains only one genus, the Caryocar, the Rhizobolus of Gantner and Pehea of Aublet ; a genus remarkable 

 for bearing the Butter and Saouari, or Suwarrow, nut. The last is not unfrequent in our fruiterers' shops. It 

 is sweet and palatable, containing a rich oil, and the pulp is dry, not buttery as in the Butter-nut. Large 

 trees, natives of Guiana and Essequebo; propagated in our stoves by cuttings, in sand under a bell-glass

One of the distinctive peculiarities of this order consists in the petals having an additional lobe in ths 

 inside, or a tuft of hairs instead. Nearly all the plants have compound leaves, and bunches of white flowers ; 

 a few of them are twining herbs, but the greater part are trees or shrubs, all natives of the warmer parts of 

 the world, and, in a great proportion, of the East. The only genus which will bear the climate of England is 

 Kolreuteria, a fine shrub or small tree, with panicles of white or pale yellow flowers. Nephelium and 

 Dimocarpus are both genera bearing excellent fruit. The rind of the berry of Sapindus Saponaria is of a 

 soapy quality, as the name of the plant indicates. The pulp of Melicocca and the arillus of Bligh/a sapida 

 are excellent eating. Cuttings, layers, or seeds.
