The vascular supply to the ovary of ten plants belonging to nine genera of the Rutaceae is described. The location of the fused carpellary ventrals of the same carpels opposite the loculi inRavenia spectabilis andLuvunga eleutherandra indicates that it is same as in the case of plants with an axile type of placentation. The septal position of the fused carpellary ventrals of adjacent carpels in plants likeGlycosmis pentaphylla, Feronia limonia andAtalantia monophylla is suggestive of its being of an anatomically parietal type, though morphologically axile. In the remaining five plants,i.e., Ruta graveolens, Murraya paniculata, andM. Koenigii, Citrus medica var.limomum andAegle marmelos, the condition is intermediate between anatomically axile and parietal types. In conclusion it may be said that the family shows a general trend for attaining a parietal type of placentation from an axile type, as in the allied taxa like the Meliaceae, Rhamnaceae, Vitaceae and the Zygophyllaceae.
