An ovule which becomes curved so that the nucellus and embryo sac lie at right angles to the funicle is :-

Ovules are classified by the position of the nucellus and micropyle relative to the funicle (stalk).
Orthotropous (atropous): straight ovule; micropyle, chalaza and funicle lie in one straight line (e.g. Polygonum).
Anatropous: the ovule is inverted, so the micropyle lies close to the funicle (most common type).
Hemitropous (hemianatropous): the body of the ovule (nucellus and embryo sac) is turned so that it lies at right angles to the funicle (e.g. Ranunculus).
Campylotropous: the body of the ovule is curved so that the micropyle points towards the base, and the embryo sac is curved.
So an ovule whose nucellus and embryo sac lie at right angles to the funicle is hemitropous.
