In this paper the floral ontogeny and the ovary development of rivina humilis l. were observed. the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals. the abaxial one initiated first, then the adaxial one, finally the lateral two initiated nearly simultaneously. the third one initiated on the position near the first tepal, and there is a gap between itself and the second tepal. ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time. ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed, therefore an elliptic orifice was formed at the adaxial position of ovary, which was the remainder of the mouth of ovary before the ovary was fused completely. with the ovary maturing, the orifice was narrowed because of the ovary growth, at last fused completely. the gynoecium is composed of a single carpel. ( 4 ) in the series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed

The feathers attached to the arms and the tail evidently possess the structures of " modern feathers ", which consisting of the central shafts ( rachis ) and parallel barbs. dromaeosaurids are unusual group of maniraptoran theropods. they share many similar or the same features with archaeopteryx or other primitive birds, such as : u - shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and " modern feathers " with rachis and barbs etc. these facts indicate not only that dromaeosaurids had developed many bird - like characters in course of the advanced maniraptorans toward birds, but also that there seemed to be the co - evolutionary trend between the feathers and the skeletal bones
