Embryo, ovule, and ovary development were studied in Limonium perigrin
um (Bergius) following self- and cross-pollinations. Four types of ovu
le were identified on the basis of their growth patterns and distinct
morphological features. Fifty-six percent of the cross-pollinated flor
ets but only 18% of the self-pollinated florets produced embryos that
developed normally. Forty-four percent of the self-pollinated florets
produced embryos that ceased development at the globular to heart stag
e of development (within 18 days of pollination), whereas only 6% of t
he cross-pollinated embryos ceased development at a similar stage. A s
imilar proportion of self- and cross-pollinated florets (36%) failed t
o develop embryos.
