Telctngium ( Calymmatotheco ) showing Structure . 165 
Count Solms-Laubach, in a recent review 1 of my preliminary note to 
this paper in the Annals of Botany, 1902, stated that the agreement between 
the new species and C. Stangeri is not perfect owing to the absence of 
thorn-like emergences on the back of the sporangia in the new species. 
This was in reference to Stur’s Plate VIII, figs. 5 and 6, which show 
emergences on the lobes reminding one of the glands on the newly dis- 
covered outer envelope of Lagenostoma Lomaxi\ and it is of course 
possible that this may be shown by Drs. Oliver and Scott to be their 
nature. This valuable criticism is met by my present action in with- 
drawing the new synangium altogether from Stur’s genus and founding 
a new one. 
In 1877 a paper 2 by the late Mr. C. W. Peach was read before the 
Geological Society describing some beautiful casts 3 of a smaller form of 
Telangium , hitherto known as C. affinis (see Fig. 12). He found them 
attached to fronds of Sphenopteris affinis , and suggested that they were 
parasitic upon them. c Each flower-like form ’ (Mr. Peach’s expression for 
the synangium) ‘ is about | in. over and fully that in height.’ 
Mr. Peach compared his specimen with that of C. minor as figured by 
Dr. Stur, p. 237 of his ‘ Culm Flora/ and it is not impossible that C. minor 
may be a Telangium. 
By the kind permission of the Council of the Geological Society I have 
been enabled to reproduce two of Mr. Peach’s figures (Fig. j 2 a and b). 
The form of T. affine is very like that of T. Scotti , but it is distinctly 
smaller. The dimensions as kindly given me by Mr. Kidston are as 
follows : — 
Length, 2*5 —3*5 mm. 
Breadth, 275 — 3 „ (after dehiscence). 
Those of T. Scotti are as follows : — 
Length, 4 ‘ 5 — 5*5 mm. 
Breadth, 3 „ (before dehiscence). 
The figure in the text is reproduced from a photograph kindly made 
expressly for this paper by Mr. Kidston of a specimen of T. affine in his 
possession. It is noticeable that the synangia of T. affine are represented 
sometimes in approximation and in planes parallel to one another 
(Fig. t 2 a). This seems to have been the case also in T. Scotti , as is 
shown in Figs. 3, 4, and 5. These specimens of T. affine were found by 
Mr. Peach in the Calciferous Sandstone rocks of North Britain, and the two 
species thus belong to different horizons.
