The mowt iiumerous principally l-seriate, 4 to 10 cclLs in 

 height and simple {Ein fâche Markstrahlen, Mikographie I. 59). 

 The other kind 4 cells wide — a few 3 or 2 — a dozen 

 cells in height ^), often composite {Zusammengesetzte Mark- 

 strahlen, Milirographie I. 59) ^), consisting of 3 stories. 

 Between the multiseriate rays innumerable 1-serate rays 

 (p. 86). The medullary rays running between almost every 

 2 radial rows of tracheids and vessels (p. 84) and in such 

 a way that nearly every fibre or vessel is in direct contact 

 with them (p. 86, see also p. 90). The cells of 1-seriate 

 rays having the sanie shape as those of the 1-seriate stories 

 of the composite rays (Plate 6 Photo 5). 



„possible that, as both Prof, Oliver and Dr. Scott hâve suggcsted 

 „to me, this is due to the rays therein l3àng somewhat oblique, in 

 „a radial sensé, so that auy transversc section passes through them, 

 „yet it remains an unusual l'eature in the truly transverse section 

 „of Ihc wood, and gives it the charactcr sliown in text-fig. 4, which 

 „8epara^es it from an}^ wood with which I am acquainted." Without 

 doubt the e.xplanation given by Frof. Oliver and Dr. .Scott is 

 the right one. In our investigations we hâve very often met with 

 the samc phenomenon, which is represented in a considérable number 

 of our figures, c. g. 16, 2i, 3i, 38, 40, 41 etc , also in that oî Eurya 

 acunihutta, given below. 



1) Plate 6 Photo 5 shows that thèse rays can be at least 3 timcs 

 this number of cells in height. 



2) The term zusammengesetzte Marksiralilen was first used by 

 us in our Mikrographie as cited above. The définition of the term 

 is give there as follows: „aus in senkrechter Richtung ùbereinander 

 gestellten, regelmâssig abwechselnden 1- und mehrschichtigen Teilcn 

 ziisammengesetzt. Die einschichtigen Telle fast immer aus aufrechten 

 Zellen aufgebaut; stets das' oberste und unterste Stockwerk bildend. 

 Die mehrschichtigen Telle fast immer aus liegcnden Zellen aufgebaut." 



The study of p. 87 of Mrs. S topes' paper, text-fig. 3 and 5, 

 Plate (5 Photo 5 and Plate 8 Plioto 11 will convince the reader, 

 that our- description, as given in the text, is correct.
