Anatomical studies in the flower of some genera in the Geraniales

Observations on the vascular anatomy of the flower inTristellateia australis A Rich andStigmaphyllon ciliatum A Juss of the Malpighiaceae andSisyndite spartea E Mey andGuaicacum officinale Linn. of Zygophyllaceae are presented. These studies record varied forces of cohesion and adhesion between vascular traces to different floral whorls. The sepals and petals are unequal in size and a little oblique in some cases. Obdiplostemony is of less prominence and a disc is absent. There is a weaker cohesion of carpels, evidenced both; morphologically as well as anatomically. Placentation is axile. The vascular anatomical characters of the flower appear to be distinctive and exhibit a lower level of specialization as compared to the other Geraniales.
