PILULAEIA. 213 



separated by partitions radiating from the centre ; they are 

 from one to four inches long. 



The fructifications consist of small globular spore-cases, 

 attached by a very short stalk to the stem at the points 

 whence the leaves and roots proceed, being in fact seated at 

 the base, or in the axils of the leaves. They are densely 

 covered externally with pale brown jointed hairs, and are 

 about the size of a small pea or pepper-corn. These spore- 

 cases are typically four-celled,, and when quite mature, open 

 at the apex, and divide into quarters, the four parts re- 

 maining attached to the footstalk by their base. The spores 

 are attached to the interior of these valves along their centre, 

 forming four lines, the lower part of the spore-case being 

 occupied by the large, and the upper part by the small 

 powdery bodies already mentioned; the former are of a 

 greyish colour, and have a roundish-oblong form, with a con- 

 traction in the middle, and a terminal nipple-like point, the 

 latter consist of oblong pale yellow bodies filled with a 

 powdery matter resembling pollen; both are contained in 

 transparent gelatinous bags. 



The larger spores have been regarded as pistils, and the 

 smaller ones as anthers, by those who have maintained the 

 sexuality of these plants ; but there is no evidence whatever
