Two of thedivisions, of one of which the stigmatic tissue atone is visible,bear normal amphitropal ovules ; the third division bearsovaries instead of ovules, or it ovules, they are orthotropal. Itwill be observed that the two upper ovaries show the suture,the lower one not; because they are arranged round a reducedaxis, the corresponding stigmatic tissue being entirely wanting. 2. One of the ovaries more highly magnified, showing two orthree ovules towards the base. Since the foregoing remarks were \vritten, othercapsules have occurred, confined, however, to a singleplant, which throw a little more light on the natureof the placenta. In these, as in the former case, wefind it in the full-grown capsules divided into threedistinct lobes, one or more of them bearing trans-formed ovules and entirely free above, the othernearly in the normal condition and showing clearlythe prolongation
