HAB. On the ground, near Rosslyn, Mr. E. Maughan. Wood near 

 Aberdeen, Mr. Jackson. Selkirkshire, near the borders of Peebles- 

 shire, Mr. J. Stewart. 



Peduncles about an inch high, red, tuberculate, arising from a small 

 brown, oblong, apparently scaly bulb ; their scales, however, are 

 really leaves, very minute, 'and cut into a number of capillary seg- 

 ments, membranous, without nerve, but strongly reticulated, and 

 resemble the leaves of some Jungermannue. Capsule nearly plane 

 above, gibbous beneath, inclined, having at its base a small cylin- 

 drical apophysis. 



This is a most remarkable plant, having little resemblance to any 

 other moss j and to me it is rendered more interesting, as I was, 

 when a very young Botanist, the first discoverer of it, as a native 

 of Britain. Yet, notwithstanding the labour I had bestowed, in 

 drawing and describing it for the Flora Londinensls, I entirely over- 

 looked the true nature of the scale-like processes upon the little 

 bulbs at the base, which Mr. Brown has ascertained to be leaves. 

 Noble specimens from Selkirkshire, some with 2 or more peduncles 

 arising from the same bulb, have been communicated to me by the 

 late Mr. J. Stewart of Edinburgh, a gentleman of high botanical 

 attainments, from whom I had hoped to have received much assist- 

 ance in the course of the present publication ; but whose death, un- 

 fortunately for science, occurred ere the first sheet was sent to 

 the press. He died at an early age, while on the eve of a voyage 

 to South America, a victim to intense application to literary pursuits.
