  abstract = {{T}he {R}oyal {C}reeper, {O}xera pulchella subsp. grandiflora ({D}ubard) de {K}ok ({L}amiaceae) is a {N}ew {C}aledonian threatened endemic taxon with high ornamental potential. {P}ropagation by cuttings has till now been the main propagation method for ornamental uses. {A} characterization of the seed biology is required in order to promote a better development of {O}. pulchella subsp. grandifiora ornamental potential, through maintaining its genetic diversity and its conservation. {A} seed analysis was conducted to define seed structure, germination conditions, dormancy, and desiccation tolerance. {S}eeds were shown to be of exalbuminous type with a permeable endocarp. {S}eeds displayed a non-deep physiological dormancy. {W}hen desiccated by equilibration in nine atmospheres with controlled relative humidity, seeds desiccated to lower water content (2.8 +/- 0.5% of fresh weight) displayed a germination rate of 63 +/- 13% compared to non-desiccated control, indicating that {O}xera pulchella subsp. grandiflora seeds were desiccation-tolerant. {P}rotocols combining seed desiccation and low temperatures storage revealed that seeds desiccated in an atmosphere with a relative humidity of 45% and conserved at 4 degrees {C} were viable after one-year period storage, with a germination rate of 50%. {O}ur study shows that a characterization of physiological traits of seeds, such as germination, dormancy and desiccation tolerance, may lead to favoring the seed as a means of propagation for ornamental uses and conservation.},
