Allied to No. 49, but both the Brunssum specimens show this pointed shape, 

 finer venation, and smaller size. 



PI. XX, fig. 15. 



Fig. 15 represents a minute spirally coiled organ, not a fruit or seed. 



Length 2.6 mm. Reuver. 



GALLS. 



PI. XX, figs 16, 17. 



These are probably leafsgalls. 



Breadth 2.5 mm. Reuver. 



PI. XX, fig. 18. 



We are unable to make any suggestion as to the organ shown in this figure; it 

 does not appear to belong to a fruit. 



Length 1.3 mm. Swalmen. 



PI. XX, figs 19, 20. 



These may be detached portions of some larger organ; we cannot identify either 

 of them. Both were found at Reuver. 



PI. XX, figs 21—24. 



These are probably galls. Figs. 21 and 22 are from Swalmen, and have been figured 

 with only half the magnification of 23 and 24, which were found at Brunssum. The 

 largest specimen is about 2.5 mm. in length. 



PI. XX, figs. 25 a, b. 



This looks like a gall of very peculiar structure. The cap a became detached from 

 the scar in the upper part of b. Swalmen. 



PI. XX, fig. 26. 



Internode flattened laterally and constricted above and below. Midrib channelled, 



primary veins impersistent scabrid about 15 on each side, surface between faintly striate. 



Length 2.5 mm., breadth 1.5 mm. Swalmen. 



Professor J. W. H. Trail, of Aberdeen, kindly offered to examine some of the 

 doubtful galls found among the seeds, and duplicates were sent to him. He writes "I 

 have made as careful an examination as I could with lens and low power of microscope, 

 as opaque objects, and my conclusions are stated below. I need hardly say that they are 

 suggestions only ; for it is very unsafe from the exterior only to dogmatise about the 

 maker of a gall.
