ORDERS OF LmNJJtrS. 
2. Angiosperma. From angio, signifying bag or sack, 
«s„o^c ;„ « , u added to spermia, implyinsj that the seeds 
Beeds nnmerous in a capsule. ^ j l J !D 
are covered. 
The orders of the 14th class, Tetradynamia, are two, both 
distinguished by the form of the fruit. 
1. SiLicuLosA ; fruit, a silicula^ or roundish pod. 
2. SiLiQUOSA ; fruit, a siliqua, or long pod. 
The orders of the 15th class, Monadelphia, and of the 16th 
class, Diadelphia, are founded on the number of stamens / that 
IS, on the characters of the first twelve classes, and they have 
the same names, as Monandria, &c. 
The lYth class, Syngenesia, has its five orders distinguished 
by different circumstances of the florets, as : 
1. Equalis; stamens and pistils equal^ ov in proportion; tliat 
is, each floret has a stamen^ a pistil, and one seed. Such 
florets are caHed perfect. 
2. SuPERFLUA ; florets of the disJc perfect, of the ray contain- 
ing only pistils, which without stamens are sfwperfAious. 
3. Frustranea ; florets of the disk^ perfect, of the ray neutral, 
or without the stamen or pistil ; therefore frustrated, or 
useless. 
4. Necessaria ; florets of the dish staminate, of the rwy pis- 
tillate / the latter being necessary to the perfection of the 
fruit. 
5. Segregata ; florets separated from each other hy partial 
calices, or each floret having a perianth. 
The orders of the 18th class, Gynandria, of the 19th class, 
Monoecia, and the 20th class, Dioecia, depend on the number 
of stamens. 
The orders of the 21st class, Cryptogamia, constitute six 
natural families. 
1. FiLicEs, — includes all Ferns, having the fruit on the leaves. 
2. Musci, — Mosses. 
3. Hepaticae, — Liverworts, or succulent mosses. 
4. Algae, — Sea-weeds, and other aquatic vegetable produc- 
tions. 
5. LioHENEs, — Lichens, found growing on the bark of old 
trees, old wood, &c. 
6. Fungi, — ^Mushrooms, mold, blight, &c. 
Note. — No confusion is produced in taking the character of some classes, for 
orders in other classes ; for example : if we have a flower with ten stamens, united 
\y their filamen ts into one set, we know by the definition of the classes that it be- 
longs to the class Monadelphia ; because it has ten stamens, it is in the order De- 
candria.
