Very fast-germinating seeds of desert species are cryptoviparous-like

From previously published studies we have learned that very fast-germinating species have some characteristics in common with cryptoviviparous species: (1) little or no endosperm/perisperm; (2) embryos fully developed and chlorophyllous at seed maturity; and (3) very fast germination, independent of temperature. Thus, we propose that these very fast-germinating seeds are 'cryptoviviparous-like'.
