Primula vulgaris flowering. Called kusymre in Norwegian.

Springtime in Western Norway. Primula vulgaris flowering. #Phenology #Seasonality #Heterostyly

A line drawing of two flowers in longitudinal section illustrating heterostyly. The left flower is labeled "Long-styled form," and the right flower is "Short-styled form."

Primula veris is heterostylous with long- and short-styled morphs. Only cross-pollinations result in seed. Darwin was fascinated by this dimorphism within a single species. I give you Figure 1 from The Different Forms of Flowers on Plants of the Same Species. #heterostyly #Primulaceae #Botany 🌾🧪🌱

New preprint! In collaboration with @ergabiodiv.bsky.social, we explored the convergent #evolution of the S-locus #supergene controlling distyly in the #primrose family.

A diagram overtop a cross-section of an Oxalis pes-caprae flower. Each part of the flower has a label. On the left says "Anthers" and points to two layers of anthers (one at the top of the flowe and one at the bottom). On the right it says "petals", "stigmas" "style" and "sepals".

A series of three photos showing cross-sections of Oxalis pes-caprae flowers. The first image shows the short-styled morph. The middle is the mid-style morph and the last is the long-styled morph.

#Oxalis pes-caprae, a plant with a unique feature called #heterostyly. This is a floral polymorphism where individuals in a species have variation in the position of their reproductive organs (specifically stigma and stamen). Oxalis pes-caprae is #tristylous, meaning it has three floral morphs.

Now accepted for publication in the New Phytologist! Stay tuned for the final, and in our opinion improved version, on the journal homepage! Big congrats to co-first authors @panazerv.bsky.social & @zopos.bsky.social and all coauthors! #Linum #supergene #distyly #heterostyly

Yellow zygomorphic flower of Wachendorfia paniculata. Dotted lines indicate the xy coordinates of its sex organs; Stigma coordinates are represented in each system by red lines, and anther coordinates by light green, dark green, and blue lines. Photo by Steven D. Johnson

Close-up photo of the palm of a hand holding two forsythia flowers with the corollas longitudinally dissected. One flower has a long style; the other has a short style. Arrows are on the photo to show the stigmas.

I just learned (from the literature) that Forsythia (#Oleaceae) is heterostylous! I have 2 spp. in my garden: some legacy plants (F. x intermedia?) & F. koreana. The legacy plants (Left) are all long-styled; F. koreana (R) is short-styled. Check your forsythias. #Heterostyly #Botany #PlantScience 🌾🧪
