History, Use, Propagation, Culture, 
24. Zostera. From ic^trryi^, a riband ; the leaves of Z. oceanica are a foot long and an inch broad, resembling 
a riband. La Zostere, Fr., and Seeiang, Ger. This plant abounds on the coast of Yarmouth, where it is 
thrown on shore in such abundance that mounds are made with it to enclose the encroachments of the sea. 
It is also used as thatch, and said to endure for upwards of a century; by exposure it bleaches white. In 
Sweden and Holland it is used as a manure, and is preferred to hay for stuffing beds. Horses and swine eat it, 
but cows are not fond of it. The rush-like envelopes of Italian liquor-flasks are prepared from this plant. 
25. Chloranthus. So named from green, and ai/^o?, a flower, on account of the greenish hue of its 
inconspicuous inflorescence. The structure of the flower is very curious, and so anomalous, as to render it diffi- 
cult to tell to what class of Linnsus it is referable. For further remarks upon this subject, see Mr. Lindley's 
Collectanea Botanica, p. 17. 
26. Corispermum. From y^n^n, a bug or tick, and (TTi^/j^oc, a seed. Le Corrisperme, Fr., and Ber Wansen- 
Class II. — DIANDRIA. 2 Stamens. 
This class, which is not large, and so entirely artificial that no other characters than those of the Linnsean 
definition can be assigned to it, contains some elegant and fragrant plants belonging to Jasmineje, Scrophula- 
rineffi, and Labiataa : examples of the two latter orders are Veronica and Salvia, extensive genera chiefly of 
hardy herbaceous plants. The most useful of the class are the pepper and the olive : the jasmine is used in per- 
fumery ; the sage and rosemary in cookery ; and the privet and syringa for garden hedges. One or two species 
are employed in medicine; several are border flowers; but the greater number of the class are plants of 
curiosity. 
Codarium is a leguminous plant, and is Widely removed from its natural place, which is Diadelphia ; so are 
Salvia, Monarda, Rosmarinus, Veronica, and many others, which would have been naturally referred to Didy- 
namia. 
Under this class Persoon has placed the genus Gunnera, which Willdenow injudiciously referred to Gynan- 
aria. A great variety of diandrous plants are scattered through the other classes of Linnaeus ; but as such 
plants are chiefly, with the exception, perhaps, of grasses, diandrous, on account of the incomplete formation of 
some of their stamens, the rudiments of which are usually obvious, it is scarcely necessary to particularise more 
than the following, viz. : — 
D. MONOGYNIA. Viola diandra ; Salicornia herbacea, virginica ; Anychia dichotoma ; several species of 
Boerhaavia. D. DIGYNIA. Polycnemum salsum ; Bufonia tenuifolia. D. TRIGYNIA. Holosteum diandrum. 
Order 1. MONOGYNIA. ^ Stamens. 1 Style. 
§ 1. Flowers complete, inferior, monopetalous, regular. 
30, Codariwn. Cal. 5-cut, with a persistent tube. Cor. flattish. Legumen one-seeded, filled with a soft fsecula. 
31. Maytenus. Cal. 5 lobed. Cor. campanulate, entire. Caps, compressed, 2-valved, with 2 cells, and 2 seeds.
