Distyly (Evolution 🧬)
Distyly is a breeding system in plants that is characterized by two separate flower morphs, where individual plants produce flowers that have either long styles and short stamens or short styles and long stamens. However, distyly can refer to any plant that shows some degree of self-incompatibility and has two morphs if at least one of the following cha...

The study provides the first detailed comparison of female cone development timing in Araucariaceae, highlighting how conserved structures can differ in developmental timing. (8/8)

Genetics of Alternating Sexes in Walnuts
Scientists have uncovered a genetic mechanism in walnuts and their ancestors that has remained stable for 40 million years. Male-first or female-first flowering, balanced by a single genetic locus, parallels sex determination in animals. This evolutionary trait ensures genetic diversity, with distinct pathways evolving independently in walnuts and pecans.

Distyly (Evolution 🧬)
Distyly is a type of heterostyly in which a plant demonstrates reciprocal herkogamy. This breeding system is characterized by two separate flower morphs, where individual plants produce flowers that either have long styles and short stamens, or that have short styles and long stamens. However, distyly can refer to any plant that shows some degree of sel...

Heterogamy (Genetics 🧬)
Heterogamy is a term applied to a variety of distinct phenomena in different scientific domains. Usually having to do with some kind of difference, "hetero", in reproduction, "gamy". See below for more specific senses.
Epigeal (Ecology 🏞️)
Epigeal, epigean, epigeic and epigeous are biological terms describing an organism's activity above the soil surface. In botany, a seed is described as showing epigeal germination when the cotyledons of the germinating seed expand, throw off the seed shell and become photosynthetic above the ground. The opposite kind, where the cotyledons remain non-photosynthetic, inside the s...
