gation. Some are filamentous, some gelatinous like 

 Funwi; some coriaceous or crustaceous ; some her- 

 baceous, in a manner leafy, and more akin to otlier 

 plants. Organs analogous to Stamens and Pistils 

 are in some altogether unknown, in some more con- 

 spicuous, and in others well known, differing greatly 

 among themselves as to structure and situation." 



This Order consists chiefly of Submersed Algce, 

 fig. 123-128, and Lichcnes (90), fig. 116-122, with 

 which a few Fungi are confounded. The " well- 

 known*' fructification is attributed to the Lichcnes, in 

 which however scarcely more than the Seeds have 

 been ascertained. These generally are 8 together, 

 in separate tubular parallel vertical cells, sunk in a 

 horizontal or convex disk, exactly as in some Fungi, 

 particularly the genus Peziza; a coincidence too little 

 noticed. 



Ord.3. Hepatice. fig. 114, 115. Herbaceous, 

 creeping, many-rooted plants inhabiting damp places, 

 whose Fructification is monoecious or dioecious, ap- 

 parently of a various and complex nature, but not 

 perfectly understood. The Seeds are often attached to 

 elastic fibres, and send out Radicles from underneath. 



Jungermannia, Marchantia, &c. are examples. 



Orel 4. Musci. fig. 105-113. True Mosses (90), 

 whose Fructification, as now well understood from 

 the investigations of Hedwig, is generally mono- 

 ecious. The Barren Flowers (66) consist of an 

 indefinite number of jointed tubular bodies, dis- 

 charging a volatile Pollen (58); the Fertile ones
