494 CRYPTOGAMIA. 



rolla or veil of some of the genera is like 

 that of Mosses, bat usually bursts at the 

 top. The barren flowers are unlike the 

 organized stamens of the last-mentioned 

 plants, being either undefined powdery- 

 heads, as in J unger mannia, see Hed wig's 

 Theories t. 15, or of some peculiar con- 

 formation, as in Marchantia, Engl. Bot. 

 t. 210, where they are imbedded in a disk 

 like the seeds of Lichens, in a manner so 

 contrary to all analogy, that botanists can 

 scarcely agree which are the barren and 

 which the fertile flowers of this genus. The 

 four-valved capsule of Jungermannia, with 

 the veil bursting at its' summit to let the 

 fruit-stalk pass, may be seen in Engl. Bot. 

 t. 185, 186, which are both frondose spe- 

 cies, like J. epiphylla, t.771, whose calyx 

 as well as corolla are evident ; and t . 605 — 

 608, which have apparently distinct leaves, 

 like Mosses. Anthoceros, t. 1537, 1538, 

 is a curious genus of the Hepaticce. 

 Linnaeus comprehended this Order under 

 the following one, to which it is, most 

 assuredlv, far less akin than to the fore- 

 going.
