larger than in the outer; the breadth of medullary rays sometimes 
smaller in the inner part of the ring. Vessels for the rest uniformly 
distributed: with a few exceptions isolated and standing separated 
-from each other in the radial rows of fibre-tracheids (Plate 6 Photo 
4, Plate 7 Photo 6, Plate 8 Photo 10 and text-fig. 1); in one or two 
cases 2 vessels standing adjacent in the tangential direction, but such 
pairs are rare (p. 85) and disturb remarkably little the radial rows 
of the fibre-tracheids (p. 86). Fibre-tracheids: the wood appearing 
be entirely composed of fibre-tracheids ; arranged with considerable 
regularity in radial rows (p. 86). Wood parenchyma scarce and 
possibly wanting; several times lying just behind vessels, spanning 
the distance between the rays (text-fig. 1 and p. 86). Medullary rays *) 
in 2 kinds. The most numerous principally 1-seriate, + to 10 cells 
in height and simple (Linfache Markstrahlen, Mikrographie I. 59). 
The other kind 4 cells wide — a few 3 or 2 — a dozen cells in 
height *), often composite (Zusammengesetzte Markstrahlen, Mikro- 
grapbie 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 
1) A character, described by Mrs. Sropes (p. 87) as a noticeable feature, is the 
way of dying out or dwindling down to 1 cell thick in transverse section of the 
broader rays (Pl. 6 Photo 3 and 4 dm and text-fig. 4). The authoress says herself: 
“while it is very possible that, as both Prof. Otiver and Dr. Scorr have suggested 
“to me, this is due to the rays therein lying somewhat oblique, in a radial sense, 
“so that any transverse section passes through them, yet it remains an unusual 
“feature in the truly transverse section of the wood, and gives it the character 
“shown in text-fig. 4, which separates it from any wood with which I am acquainted.” 
Witliont doubt the explanation given by Prof, Outver and Dr. Scorr is the right 
one. In our invesligations we have very often met with the same phenomenon, 
which is represented in a considerable number of our figures, e.g. 16, 24, 34, 
38, 40, 41 etc, also in that of Eurya acuminata, given below,

2) Plate 6 Photo 5 shows that these rays can be at least 3 times this number 
of cells in height. 
3) The term gusammengesetzte Markstrahlen was first used by us in our Mikro- 
graphie as cited above. The definition of the term is given there as follows : 
“aus in senkrechter Richtung übereinander gestellten, regelmässig abwechselnden 
1- und mebrschichtigen Teilen zusammengesetzt. Die einschichtigen Teile fast 
immer aus aufrechten Zellen aufgebaut ; stets das oberste und unterste Stockwerk 
bildend. Die mehrschichtigen Teile fast immer aus liegenden Zellen aufgebaut.” 
The study of p. 87 of Mrs. Stopes’ paper, text-fig. 3 and 5, Plate 6 Photo 5 
and Plate 8 Photo 11 will convince the reader, that our description, as given in 
the text, is correct.
