almost to the seed. Some specimens show fine’ lines on the cupule 
which may mark the position of fibro-vascular bundles. The seed 
(plate 10, figures 6, 9, 11, 12; plate 11, figures 1, 2) is broadly oval 
to round; the impression of it is very distinctly shown in the larger 
and older fructifications, and can be distinguished even in the 1imma- 
ture ones (plate 10, figure 5). The meastirements of some of the 
larger seeds are as follows: 5.3mm x 2.5mm; 5.6mm x 3.1mm; 
6.4mm x 3.4mm; 6.3mm x 3.4mm. On several slabs were found 
groups of small rounded thick bodies, some of them free, others 
attached to pedicels, plate 11, figures 3-5, which have every appear- 
ance of being seeds. The largest of these bodies vary from a length 
and width of 3mm to a length of 3.2mm and a width of 2.7mm.

cupules, and borne terminally on branches of the rachis, x34. (From Scott, 
1909, after Arber) 
Some specimens are slightly wider than long, but this, I think, is 
due to distortion in preservation. These bodies are, I believe, the 
seeds without the integument, the nutlets; their general character 
and thickness carry out this idea, and in addition portions of what 
appears to be the integument are sometimes seen along the margins 
of some of the nutlets. 
Microsporangia. The sporangia-bearing organs of Kos perma- 
topteris, as in the case of the seeds, are borne at the tips of 
forking branchlets. There is one specimen in which these organs are 
borne close to the dichotomy; and another specimen, plate 11, figure 
6, in which these organs are borne some distance from the dicho- 
tomies, and yet close enough together to give a clustered effect. In 
both cases, the sporangia-bearing organs are in a young condition. 
The older specimens in our hands, in all but one case, have become 
separated from the pedicels.
