Abstract
Cuscuta conforms to the floral formula: K (5), C (5), A 5, G (2). The thalamus contains ten to fifteen discrete collateral bundles. The sepals, petals, and stamens are one traced each. Phloem is more abundant than xylem in the bundles. Nonvascular staminal scales occur at the bases of the stamens on the corolla tube. The base of the ovary acts as a nectariferous disc. Resinous cells occur in all the organs of the flower especially in the ovary wall. Besides the carpellary dorsals, some more stelar bundles enter the ovary wall. The dorsals continue upto the stigma but the uninverted ventral bundles directly enter into the ovules. The base of the ovarian chamber is filled with a placental tissue which fits in between the receded carpellary margins, thus completing the septum. Placental obturator forms canopy over the micropyles of the inverted ovules.
