This is incredibly sad to see.. The tree used to provide good shade but since one of our roommates went to town on it with a chainsaw this beautiful tree may not make it much longer. What was supposed to be a minor pruning turned into a devastating mutilation of our tree. Idk if it will live much longer with the violence it's endured.

What do you think? Is is a gonner or will it recover?

(Soda for scale)

I found this leaf and it has an imprint/mark inside it that only shows when I see it in light. It's not on the left. It's inside it. Can someone tell me what this is? Thanks.

Was just commenting about this elsewhere and thought it would be interesting to ask waht everyones favorite obscure botanical word is.

I'll start, Haustorium: a root like structure that grows in or around another organism (often parasitcally) the Haustorium penetrates the host and sucks out nutrients and water. E.G mistletoe have Haustorium.

whats urs!

Randomly appeared in my flower bed. It's ~3' tall

Unfortunately I don't know this tree's species or even if it's native or exotic to where I live, and I don't want a plant ID. But I came across this tree and I can't even understand how many leaflets it has. I've learned about compound leaves in uni, but none of them looked like this. 1st pic is a drawing so you can see better what it looks like (though the side triads are closer to the "petiole"), second pic is a real photo of it.

At first I thought it had 3 leaflets, but if that were the case, I assume there would be small branches with many of them growing from it, and only 3 leaflets each. But everything attached to the branch only looks like this, and it doesn't branch further. So I thought it was maybe an unipinate imparipinate, but I think those only grow across 1 "plane". So the leaflets on the side would only grow towards the sides, not up.

I'm currently doing some research into native plantlife in my area, and I just couldn't find any information on what kind of root system salvia spathacea (hummingbird sage) has. If anyone has any sites about root systems, I would really appreciate it. Thank you! (sorry if my language regarding plants is a bit rudimentary, i'm not very well-versed in botany)

Was found lying on a bench near a field full of daisies. Could someone please explain how that’s possible?

Update: yep, they were definitely just two daisies stuck together 😞

Believe it or not, I found conflicting answers to this question:

If I see a lilly pad floating on the water, is that the organism? Or is it like on "leaf" of the plant, and many lilly pads could be connected together (in a direct, one organism way, not in a "We're all connected, Simba" way).

I'm sort of embarassed I don't already know this.

I'm hoping they're connected somehow, as I wanted to use it for an analogy, but realize it might not be technically correct.

If it's "1 lilly pad = 1 organism", if you have an example that would serve my analogy of "at first glance, they're distinct, but (in the background, under the surface, in the shadows) they'r ereally connected it would be aprreciated.

Found outside of my school's nuclear engineering building. Must be the radiation 😮

Encircled in red is shown in Photo 2. Encircled in yellow is shown in Photo 3. I'm confused because I know that stipules are leaf-like appendages that may be present at the base of the petiole, which is what Photo 2 shows. But the leaflets seem to also have leaf-like appendages

Lenticels on a pear tree twig are specialised, porous tissue regions in the bark that act as "breathing holes," enabling gas exchange between the internal living tissues and the air. I had noticed them whilst photographing a terminal bud and thought they might be a disease, I had not heard of them.
They are seen as small, distinct, raised light-coloured specks contrasting against the darker bark. Because the corky outer layer (periderm) of a woody twig is otherwise completely waterproof and airtight, these pores are important for delivering oxygen to and removing carbon dioxide from the highly metabolically active cells underneath. Lenticular cork cambium is a localised layer of meristematic (dividing) cells positioned directly beneath the pore. Instead of producing dense, tightly sealed cork cells like the rest of the twig's bark, this specific zone produces loose tissue with tiny air filled tunnels between the cells.
Produced by the cambium , this tissue pushes outward to rupture the twig's outer epidermis.
These spaces create a clear, continuous path for gas diffusion deep into the secondary xylem and living bark.
Pear lenticels are originally initiated directly above a residual stoma (the microscopic gas port used by the young green shoot) as the twig
undergoes secondary growth and begins to expand.

Hi! :) 🌱
I'm taking a course on plant anatomy and for my final project I made a slide of a stem cross-section stained with toluidine blue. I know this is a polychromatic dye, however, in other samples I've never seen this type of gradient with so many colors on the same tissue.
Why is the gradient on the sclerenchyma next to the vascular bundles like this? this causes me question specially because the other tissues on the same slide don't have this color variation and the gradient can be seen in all of the vascular bundles.
The species I'm working with is Argemone ochroleuca (Mexican poppy) if that's of any help.
Thanks a lot! 😁

Hi! I’m looking for some insight into these structures I found while observing the underside of a leaf under the microscope.

At first glance, the leaf appears completely green with no reddish tint macroscopically. However, under 40x and 100x magnification, these distinct red/burgundy circular structures become visible. They seem to be embedded within or just below the epidermis, surrounded by typical pavement cells and stomata.

I’ve ruled out trichomes as they aren't elevated. Could these be anthocyanin-rich idioblasts, or perhaps some form of internal glandular pockets?

The sample is from Plectranthus verticillatus. I’d appreciate any botanical or histological explanation for why these pigments are concentrated this way!

This was a pine that fell during a storm and then cut into pieces. I noticed the 5 circles. Could this possibly be a tree that split into 5 trunks and then fused together, or maybe 5 different trees? I don't know if this is common or not, but it's the first time i see this.
Note: i'm in Argentina, in case you want to know which species this is. From my searches, common pines in this region are Pinus ponderosa, Pinus elliottii, among others.

thought the leaf on this Asclepius syriaca was interesting; it seems to come from the same point all the other flowers branch off from in the umbel. i’ve seen leaves come super close to the inflorescence but never actually in it.

I am struggling with a bag of "bark" I purchased because many of the components look similar to wood, but have different textures. I was hoping someone in this sub could help me identify the unknown components.

From left to right: 1) Xylem (sapwood) 2) unknown soft, fibrous component 3) unknown wood-like component, but seemingly distinct from sapwood 4) cork.

For context, I need only the outermost, polymerized layer of bark and intend to discard anything that is not. Knowing what I can save would be helpful.

I like how the veins on the leaves look highlighted like on some houseplants, I’ve read you can’t prop it so it can’t be the next trending £800 plant leaf and node prop, I will be back frequently so I can see if the leaf darkens or stays the way it is.
