“…4) Capparaceae: The Capparaceae exhibits a fairly uniform plan of vascularization of the flowers. The floral vasculatures of six genera and 11 species have been described (Raghavan, 1939;Stoudt, 1941;Puri, 1950). Morphologically, the flowers of Koeberlinia resemble those of many genera of the Capparaceae, and this is why Koeberlinia has commonly been associated with this family.…”

The in toto pattern of the floral vasculature in Koeberlinia Zucc, is distinctive. The median vascular trace to each sepal is concrescent with the antesepalous stamen trace forming a trace complex. Each petal trace is concrescent with the nearest antestaminal trace, and this common trace is in turn concrescent basally with the common basal supply to the adjacent sepal margins. The ventral carpellary bundles and the ovular traces of the two carpels are arranged for part of the ventral carpellary system into an essentially continuous hollow stele‐like cylinder and many of the ovular vascular supplies originate from this strand. All vascular concrescences are congenital. Comparisons of the morphological and floral vasculature characters of Koeberlinia with those of its various putative allies revealed that there are no substantial reasons for linking Koeberlinia with Canotia, Celastraceae, Rutaceae, Simaroubaceae, or Zygophyllaceae. The in toto floral vascular structure of Koeberlinia is closely similar to that of the Caryophyllaceae and dissimilar to that of the Capparaceae. Several qualitative characters of the secondary xylem of Koeberlinia differ from those of the Capparaceae, yet certain important ones are similar. Many of the morphological characters of Koeberlinia are similar to those of the Capparaceae as well as the Caryophyllaceae, yet certain critically important ones strongly indicate a relation of Koeberlinia to the Capparaceae: occurrence of myrosin cells, capparaceous pollen, capparaceous ovular characters. To include Koeberlinia within either of these families is unwise, but the writers are inclined to retain Koeberlinia in a monogeneric family within the larger Capparales.

“…A STUDY of the vascular anatomy of the flower of certain species of the Capparidaceae was started in 1938 but it was soon given up because Raghavan andVenkatasubban (1941 a, and1941 b) and Stoudt (1940) had also undertaken a similar investigation. Raghavan and Venkatasubban's papers which dealt with floral organogeny and anatomy of Crataeva religiosa and which were published in Germany during the last war, were not available to the author until they were republished in India two years later.…”

“…Recently Norris (1941) has made a detailed investigation of nectary characteristics of the Rhoeadales. Brown (1938) and Stoudt (1941) have studied the nectaries in the Capparidaceae. In all these works the nature of neetaries in the Capparidaceae has been inferred to be either staminodal or receptacular.…”

“…The nature of the gynaeceum.-The morphology of the gynaeceum in the Order Rhoeadales has been controversial for more than a century. It has been suggested that, like the crucifer gynaeceum, the capparid gynaeceum also consists of twice as many carpels as the number of placentae (Eames and Wilson, 1928;Stoudt, 1941). Stoudt has further suggestedthat in Crataeva tapia "both fertile and sterile carpels are reduced.…”

“…If it is a most primitive genus it is not, therefore, surprising that it has retained relics of its past history in the vascular anatomy of its gynaeceum. The presence of an inverted medullary vascular ring, which alone furnishes ventral bundles (or placental strands) of the carpels, is a most significant point and it is surprising that both Raghavan and Venkatasubban (1941 a, 1941 b) and Stoudt (1941) overlooked it in their material. This feature at once suggests that the ancestors of Crataeva had axile placentation-a condition that is still occasionally seen in the lower and upper parts of the ovary, and that the medullary vascular cylinder was formed by the coming together of the ventrals of all the carpels.…”
