However, in the present conditions of maturation, the percentage of embryos developing to cordiform and torpedo ontogenetic stages was low and no embryo at cotyledonary phase was seen, revealing an asynchronous development, once globular somatic embryos were formed (Table 3).
The transition from globular to cordiform stage was marked by cellular elongation and cotyledon early growth (Fig.

7 cm, lanceolate to lanceolate-oblong, basically truncate to cordiform, apically acute; interporangial scales ca.
0 cm, ovate, papiraceous, basically cordiform, apically acute to acuminate; abaxial blade scales 0.
To summarise the problem, the name cordiform came to be applied late in the nineteenth century to a large group of mathematically related maps (Fig.
At this point it is worth remembering that the cordiform maps were invented and published before the heart's function was well seen, described or understood.
or to declare his double cordiform map "twin figures of the human heart".
