DOLEROPHYLLUM

based on sections cut from a specimen in the British Museum 1 

 which, though assigned on the label (within a query) to France and 

 named Dolerophyllum Berthieri, is undoubtedly Eichwald's species 

 from East Russia. 



The specimen (fig. 430) is 9 cm. long and 4-2 cm. broad : at 

 the slightly contracted and broken base is a piece of immature 

 axis (fig. 430, B, a) 12 mm. in diameter overtopped by a mass of 

 closely packed leaves encircling one another like the bulb-scales 

 of an Onion (fig. 430 A, C) 2 . Most of the leaves included in the 



FIG. 430. Dolerophyllum Goepperti. Bud in surface-view, A; in longitudinal 

 section, B, C; in transverse section, D. (British Museum; A, f nat. size.) 



bud were attached to the axis below the broken base. The 

 curved, dichotomously branched, veins are seen on some of the 

 pieces of lamina on the surface of the bud (fig. 430, A). The 

 considerable breadth of the leaves is demonstrated by the longi- 

 tudinal and transverse sections. In fig. C most of the laminae 

 can be traced through the whole height of each of the steep-sided 

 arches : a few overlapping margins are seen in fig. D. The veins 

 are for the most parf imperfectly preserved and appear as clear

2 A specimen from Orenburg in the Dresden Museum shows the same surface- 

 features as the British Museum specimen and agrees with the originals of Goeppert's 

 figures which are in the Breslau University Museum.
