334 DESCRIPTIVE CATALOGUE 



V. 6127 n. Figured, PI. XXXI, fig. 2. A small tangential 

 section showing parts of three leaf-traces. The 

 nature of the tracheids and medullary rays of the 

 wood can be well seen. 



V. 6132. Type (or co-type). Three portions of the trunk 

 which have been cut in various directions for the 

 making of series of sections. The specimen was 

 friable and had to be soaked in balsam, but the original 

 surface can be seen in the largest of the three pieces. 



V. 6132 a. Figured, text-fig. 104. Transverse section showing 

 most of the anatomical details described above. The 

 section has been marked by small saw-cuts on one 

 side, in order to be carefully correlated with the 

 radial longitudinal section e, cut absolutely at right 

 angles to it. 



V. 6132 b. A similar transverse section, which is carefully 

 marked to show the direction of the radial and the 

 tangential longitudinal sections cut from the same 

 block. 



V. 6132 C. Radial longitudinal section in which saw-cuts 

 correspond to those in slide V. 6132 a, so that the 

 alternation of the wood-zones can be clearly seen. 



V. 6132 d. A more imperfect radial section, much of which 

 broke away in the cutting. 



V. 6132 e. A small radial section in which the anastomosing 

 bands of perimedullary xylem are well seen. 



V. 6132 f. A radial longitudinal section showing some of the 

 wood-zones in good transverse section. 



V. 6132 g. Figured, text-fig. 110, A. Tangential longitudinal 

 section of four leaf-traces just passing out from the 

 pith in the inner wood-zones. 



V. 6132 h. Figured, text-fig. 110, B. Tangential longitudinal 

 section of the same four leaf-traces further out, in the 

 position marked B on slide V. fi!32 I. The leaf-trace 

 tissues, though a little broken, can lie well seen.
