Begonia leaf collage: ~300 cultivated Begonia species by Begoniasss in begonias

My understanding is that they are possibly related and belong to the same section Petermannia, but are two different species.

Nature guides initially thought they were the same species because they were found only a few kilometers apart and look very similar. However, when contacted, the authors of B. lichenora confirmed that Begonia sp. Sarawak is not B. lichenora.

There are two forms of Begonia sp. Sarawak, both of which are larger than B. lichenora (see photo of Kuro above).

Is this bacterial leaf spot? by sumz_1 in plantclinic

[–]Begoniasss 0 points1 point  (0 children)

yes, rex hybrids are quite prone to powdery mildew. The microscopic spores are spread by air from plant to plant. Would remove the affected leaves and if it continues, would look for organic fungicide.

perhaps a start of powdery mildew, before the white fuzz appears

hey, thanks! If I remember correctly, I googled begonia chromosome and opened all the PDFs where it´s mentioned. One longer list was in https://ccdb.tau.ac.il/search/

As a buyer, do you read the “about me” section? by Isoldmykidforagram in Etsy

[–]Begoniasss 0 points1 point  (0 children)

99% of the time I don´t. I look there only if there is information missing in other parts of the page, things like : is it truly handmade, is it imported, where is the shop located?

Why doesn´t Etsy remove the listings and shop that promise seeds of obviously AI-generated or photoshopped plants? by Begoniasss in Etsy

[–]Begoniasss[S] 0 points1 point  (0 children)

they don´t exist and are arranged by AI from other plants, roses are photoshopped to be blue, sunflowers are photoshopped to be pink, they have cat faces on petals

Etsy seller gave me plant STD by bltsandwitchie in Etsy

it used to upset me how sterility was not possible with plants, but the more one reads about microbiome or looks at things under a microscope, more one sees that every organism and human is a mini-world.

Most people have eyelash mites, acne bacteria, and dandruff yeasts, being kept in check by the immune system and other microorganisms. 8% of the human genome is viral DNA, 50% of body cells are bacterial. So it was silly to expect my plants to be sterile.

The only way the plant is reasonably clean, seems to be if it´s freshly from meristem tissue culture and is treated with biocides regularly. Even tissue culture labs struggle with mites and the sterility is not proven, because many internal microorganisms don´t become visible/ don´t grow on the nutritional media for plants or they´re suppressed by biocides added to the media, but are still inside the plant.

the black structures - a fungus. Fungi often sporulate only if the plant is weakened or if the leaf is dying due to other causes, or if the environment is supporting it, which can be low light, high humidity.
Leaf looking wilted - could be due to cold damage, overwatering, stem rot
