and tr: This genus is composed of shewy flowering shrubs 
in jaroen, well adapted for shrubberies. They will thrive well

ding on the common horse-chesnut. Seeds, when they can be | 
procured, should be sown singly in rows, in the month of March 
or April, about an inch under ground ; and when the plants are 
of sufficient size, they should be planted out where they are in- 
tended to remain.

Calyx usually of 5 sepals (f. 110. a.), rarely of 6, more or 
less connected at the base, therefore it is commonly called 5-6- 
parted or 5-6-cleft. Petals unequal, usually 5 (f. 110. b.), rarely 
8, alternating with the sepals when the same number, inserted 
into the hypogynous disk with the stamens, and adnate to their 
tube. 
the disk, inner series usually shortest, with sterile anthers, with ` 
the filaments monadelphous at the base, the rest filiform, awl- 
shaped, with round anthers. Ovary free, subglobose (f. 110. e.), 
somewhat tetragonal, 4-celled, 4-seeded. Styles 4 (f. 110. d.) 
5-6. Stigmas simple. Fruit containing 4 adglutinated nuts, but 
usually fewer from abortion (f. 110. f.). Nuts indehiscent, 1- 
celled, covered with a hard shell, which is beset with bristles out- 
side. Almonds or seeds kidney-shaped, keeled on the back, ex- 
albuminous, tapering to both ends. Funicle dilated into a spongy 
2-lobed caruncle. Embryo with a very large ascending ra- 
dicle, which is the substance of the almond eaten, and with 
very small, ovate-lanceolate, leafy cotyledons, lying in the 
furrow of the radiclee—Trees with opposite, stalked, palmate, 
stipulate leaves, composed of 3-5 leaflets, and racemose bract- 
less flowers. .This is a very distinct order, approaching on one 
hand the Zerebinthacee, and especially with Mangifera, but 
from the hypogynous insertion of the petals and stamens and 
form of fruit it comes more near to Sapinddacea. It agrees also 
with Hippocastanee in the leaves being opposite, as well as 
being palmately compound, but in Hippocastdne@ the radicle is 
small and the cotyledons are large, but on the contrary in Rhi- 
Stamens very numerous, disposed in a double order on 
” zobòleæ the radicle is large and the cotyledons are small, but 
it differs also in the large regular flowers, and in the number of 
stamens. In both these orders the substance of the albumen 
appears as if it was consumed by various parts of the embryo. 
The order is remarkable for containing the Soari Saouari or 
Suwarrow-nut and Butter-nut. The first is not unfrequent in 
fruiterers’ shops. It is sweet and palatable.
