woods and four species of fossil palm roots, while Drabble* 

 has studied the root anatomy in a large number of living spe- 

 cies of palm. These papers give full citations of the literature 

 in their respective fields. 



The maximum height of the specimen (cf. figs. 1 and 2) is 

 15 cm , its breadth 23 cm , its length 28 cm , and only a small portion 

 of the base of the stem remains, most of which is less well pre- 

 served than the roots. Consequently the amount of material 

 from which stem sections could be made was not large. More-

over, in this basal region of the stem the course of the bundles 

 is considerably disturbed, so that any section cuts comparatively 

 few bundles at right angles. However, several small sections 

 were obtained with the parenchyma of the stem and the lig- 

 nified portions of the fibrovascular bundles in a good state of 

 preservation. The fact that none of the bundles retain their 

 phloem elements is perchance accounted for by the presence of 

 numerous fungus hyphse. 



The parenchyma of the stem shows no unusual features, and 

 there are no bast strands between the vascular bnndles, so that 

 in Unger's classification this species would belong to the second 

 great group. Stenzei, however (p. 43), points out that this 

 method of classification is unsatisfactory, and substitutes a sys- 

 tem based chiefly on a comparison of the arrangement, prox- 

 imity, structure, and size of the bundles in the outer and inner 

 regions of the stem ; and on the shape and size of the scle- 

 renchyma portion of the fibrovascular bundles. 



In our specimen no marked difference could be detected 

 between the inner and outer bundles (compare figs. 3 and 4),
