leaves. The figure of Poacordaites linearis, Grand' Eury in the text of 

 Weiss' book 1 shows essentially the same condition of things as the 

 figures in Grand' Eury; the few attached flowering branches bear male 

 inflorescences, and are marked by the small number of their lateral flower- 

 buds and by the unequal length of the internodes developed between them. 

 Lesquereux 2 also has figured a branch which resembles those of Grand' 

 Eury. Similar objects are extremely abundant, as may be supposed, 

 in the loose state, that is, not attached to the branches which bore them, 

 and the literature is full of illustrations of them. Grand' Eury 3 has 

 figured a large number of these remains, among them male inflorescences 

 which are remarkable for the length of the bract-scale which supports the 

 flower-bud 4 . This same form has been already described by Ettingshausen 5 

 from the Coal-measures of Stradonitz in Bohemia under the name of 

 Calamites Volkmanni, Ett. Examples will be found also in Goppert 6 , 

 Weiss 7 , Lesquereux 8 and Dawson 9 ; lastly, Schimper 10 gives figures of 

 many of these forms, and also reproductions of the more abnormal inflores- 

 cences, whi :h have been described by Carruthers n under the names of 

 Antholithus anomalus and A. Lindleyi and are figured in Balfour 12 . In 

 these the axis bears lateral clusters of compressed heart-shaped seeds on 

 long stalks and begirt with a wing-like membrane which is emarginate at 

 base and apex. In the places mentioned and in almost every work which 

 describes any number of coal-plants figures will be found of countless casts 

 of seeds, but as they have no importance to the botanist the reader is 

 referred for an account of them to Schimper's work 13 .
