 of the Vitaceae. In: Annais of Botany, Bd. 27, Heft 1, S. 133 — 139, PI. 15, 

 1913. 



This is an anatomical study of stem structure in various members of the 

 Vine family. The writer concludes that the ancestors of the Vitaceae possessed 

 interfascicular broad rays and intrafascicular linear rays in their central cylinder, 

 the genus Leea being the most primitive. The linear rays disappear in the raa- 

 ture wood of all except Yitis californica Benth. whicli is therefore considered the 

 most primitive member of the genus. In certain forms, vestiges of the linear 

 ray persist in the seedling, and it also appears after an injury.

These two related genera are typical xerophytic shrubs or small trees oc- 

 curring in South Africa. Portulacaria has decussate leaves, in Ceraria the nodes 

 are in longitudinal rows bearing many leaves at each node. The leaves are 

 fleshy, with no palisade tissue and with mucilage cells in the mesophyll. In 

 Ceraria there is also a large mucilage ring in the middle of the cortex, while in 

 Portulacaria the mucilage cells form a network in the cortex.

 tales. I. The genus Ephedra. In: Annais of Botany, Vol. 26, Heft 4, S. 1077 

 bis 1104, pl. 94—97, figs. 2, 1912. 



In this anatomical study of the stems of Ephedra, various similarities to the 

 stem-structure of certain Dicotyledons on the one hand, and of the Gymnosperms, 

 especially the Coniferae on the other hand, are pointed out. The fact that the 

 morphological features of the inflorescence are believed by some to point rather 

 towards the Bennettitales as ancestors, shows the danger of attempting to con- 

 struct phylogenies on the basis of only one line of evidence.
