ADDITIONS and CORRECTIONS. 
Descriptions of the following Natural Orders were omitted in their proper places. 
Verbena'ce.e, see folio 26. 
This order is composed of dicotyledonous trees or shrubs , or herbaceous 
plants, with generally opposite, simple or compound leaves, without stipula;. 
Their flowers are either in opposite corymbs, or spiked alternately ; sometimes 
in dense heads ; very seldom axillary and solitary. The calyx is tubular, and 
permanent. The corolla monopetalous ; with an elongated tube ; ami an irre- 
gular 4- or 5-lobed limb. The stamens are usually 4, and didynamous, some- 
times only 2. The ovary is 2- or 4-celled, and 2- or 4-seeded, with a single 
style, terminated bv an entire or bifid stigma. The fruit is a berry or drupe, 
containing a nut with 2 or 4 cells, which ate often 1-seeded. The seeds are 
upright, with a straight embryo, and very little or no albumen. — Verbena, t. 26, 
is the only Biitish genus in the order.

The plants of this order are nearly allied to the Umbellifercc. They are either 
Trees, Shrubs, or Herbs. Their calyx is adherent to the ovary, and is entire 
or cleft. Their petals are 4, 5, 10, or none. The stamens are equal in number 
to the petals, or twice as many. The ovary is 2- or more-celled, with the same 
number of styles, terminated by simple stigmas. The fruit is fleshy or dry, of 
several 1-seeded cells. The seed is solitary and pendulous, with a minute 
embryo, and fleshy albumen. — Adoxa, t. 42; and Hedera, t. 32, are now te- 
leirtd to this order, from Saxieragee and CapiufouacejE. 
Aroi'de.e, Juss. — See folio 261. 
This order is composed of monocotyledonous. herbaceous herbs or shrubs. 
Their leaves are sheathing at the base, either with parallel or branching veins ; 
sometimes compound, often heart-shaped. Their flowers are unisexual, ami 
arranged upon a spadix (see t. 261. f. l.rf), which is usually enclosed in a 
spatha, as in Arum, t. 261, or frequently naked, as in Acorus, t. 330. The 
perianthium is either wanting, or consisting of 4 or 6 pieces. In the sterile 
flowers the stamens are definite or indefinite, hypogynous, and very short ; wiih 
1- 2- or many-celled, egg-shaped anthers, winch are turned outwards. In the 
fertile flowers the ovary is superior, 1 -celled, very seldom 3 celled, and many- 
seeded ; the ovules upright, or pendulous, or parietal ; and the stigmas sessile, 
as many as the cells. The fruit is succulent or dry, not opening. The seeds 
are either solitary or several ; the embryo is in the axis of a fleshy albumen, with 
a cleft on one side, in which the plumula lies; and the radicle is ohtuse, and 
usually next the hilum, but occasionally it is at the opposite extremity. (See 
Lind. Syn.) — The Biitish genera in this order are A hum, t. 261 ; and Acorus, 
t. 330. 
Vaccinil'.e, Dec. — See folio 383. 
These are dicotyledonous shrubs, with alternate coriaceous leaves; chiefly 
inhabiting mountainous situations or high northern latitudes. Their calyx is 
superior, with from 4 to 6 more or less distinct lobes. Their corolla is mono- 
petalous, and lobed as often as the calyx. The stamens are distinct, double the 
number of (be lobes of the corolla, and inserted into an epigynous disk. The 
anthers are 2-celled, opening by 2 pores, and often furnished wiih 2 horns. The 
ovary is inferior, 4- or 5-celled, and 1- or many-seeded. The fruit is a succu- 
lent berry, crowned with the permanent limb of the calyx ; and the seeds are 
minute, wiih a fleshy albumen. — The British genera are, Vaccinium, t, 383. ; 
and Oxvcoccus, t. 429.

(2nd ed.) Suppl. p.321. 
Small annual, dicotyledonouspZaniy, with hollow, rooting stems, and opposite, 
stipulated leaves. The calyx consists ol from 3 to5 sepals, which are eiiher dis- 
tinct or slightly united. The corolla is from 3- to 5-petaled. The stamens are 
hypogynous, and as many, or twice as many, as the petals. The ovary has 
from 3 to 5 cells, and as many styles, and capitate stigmas. The fruit is a 
capsule of from 3 to 5 cells, and as many valves, alternate with the dissepiments, 
which usually adhere to a central axis. The seeds are numerous, with little 
albumen, a straight embryo, and a radical turned to the hilum. — The only 
British genus in this order is Ela'iine, t. 487.
