“…and the pores often radially arranged when in rows. They do not agree with Hoar (1915) and Metcalfe and Chalk (1950) that these differences should exclude the Cornaceae from the Umbellales. Rodriguez (1957) is inclined to aocept the rather wide range of wood struoture found within the Araliaceae as a link between the more primitive Cornaceae and the more advanced Umbelliferae.…”

New Zealand and South American species of Griselinia are compared with other genera of the Comaceae. Araliaceae. and Escalloniacea. The main features examined are the morphology and anatomy of the shoot. the anatomy of the secondary xylem, and the vasculature of the flower. While Griselinia resembles all these families in some respects it does not fit within the boundaries of any one family. The implications of the complex inter-relationships between these and other families are discussed. and it is concluded that the evidence at present available gives little support to the retention of Griselinia in the same family as Comus, though it is insufficient to settle the problem of its placement in any existing family.

“…The features of the vessel elements, i.e. dimension, end wall perforations and lateral pitting have been investigated in some members of the Umbelliferae by Hoar (1915) and by Metcalf & Chalk (1950). More detailed investigations covering 20 species representing 18 genera of the family was carried out by Roderiguez (1957).…”

Systematic studies in the genus Pimpinella L. (Umbelliferae) from tropical Africa

ABEBE, D., 1992. Systematic studies in the genus Pimpinella (Umbelliferae) from tropical Africa. Twenty species of the genus Pimpinella, mostly from tropical Africa, were studied by a multidisciplinary approach. The overall results showed that morphological and anatomical characters of the fruit were crucial in determining the generic and specific status. Pimpinella simense sensu Benth., Schimperella verrucosa sensu Wolff are recognized as Sium simense. Four recently described species are included. Pimpinella engleriana is reduced to varietal status in the new combination, P. ledermannii var. engleriana. The general evolutionary trends and the probable migration route of the genus to tropical Africa are discussed. A taxonomic treatment grouping all the species into two sections is presented along with keys and descriptions for each taxon.

“…A number of differences have been recorded between the secondary xylem in the Araliaceae and the Cornaceae (in the broad sense) (Hoar, 1915;Metcalfe and Chalk, 1957). It was hoped, therefore, that an investigation of the wood anatomy of Aralidium would provide evidence of the relationships of that genus.…”

Summary The wood of Aralidium pinnatifidium Miq. is diffuse‐porous with the vessels mainly in groups; the perforation plates exclusively scalariform with numerous bars; the parenchyma paratracheal; the rays multiseriate heterogeneous; and the fibres with simple pits and frequently septate. On balance, the wood is, therefore, more like that of the Araliaceae than of the Cornaceae. A number of differences have been recorded between the secondary xylem in the Araliaceae and the Cornaceae (in the broad sense) (Hoar, 1915; Metcalfe and Chalk, 1957). It was hoped, therefore, that an investigation of the wood anatomy of Aralidium would provide evidence of the relationships of that genus.
