ary. but in great quantities on the moist earth of the beds. 

 It forms orbicular froodes, like the Anthoceros, much 

 lobed and crenate in the margin, and plicated towards the 

 centre. The caxicbs proceed from the plicae, are large, 

 sometimes much crowded, twovalved, and containing a. 

 large oblong capsule, yellowish color, which in time falls 

 out, and leaves a hollow. The capsule is a little com- 

 pressed, and has a rim on the top — probably the opening. 

 although 1 have not seen any open — it is filled by small 

 globular yellow seeds. The diameter of a single frons is 

 often one inch — many are confluent. The color sometimes 

 green — generally a dark brown, and only greenish in the 

 margin.

This very remarkable plant I can hardly doubt is the 

 one Dickson describes, Fasc. I. p. 8. But I have not sue- 

 ceeded in observing tbe Capsules. I shall, therefore, de- 

 scribe my hepatic at length, and continue to observe it. 

 It was found in immense quantities on the ground in a 

 cornfield in December.

I am inclined to suppose that my plant is in a young 

 state, and hope to find the capsule in time. One frons is 

 at most one quarter of an inch in diameter. But a great 

 man} are contiguous. The Sphaerocarpus is a genus 

 very little known as yet in general.

 is much larger, and not by any means flat. Common.
