Dianthus ID from Steven Molteno

One needs to see the flower base (calyx) from the side view.

it's actually useful to do this with all plant photos where there are flowers. A photograph of the flower from the side helps with IDing so many plant groups,

Observation license choice

CC-BY (or CC-BY-NC) for observations [and not CC-BY-SA that we previously recommended).
CC-BY-SA for pictures and sounds (specific observations, sounds and pictures can be further restricted).

That decision goes back to before 2014, where GBIF ran a lengthy consultation, resulting in a decision to only support a limited set (CC BY, CC BY-NC and CC0) for occurrence datasets. More details are still available at https://www.gbif.org/news/82363/new-approaches-to-data-licensing-and-endorsement (especially the detailed community input collected, see the link to the summary of the consultation process at the bottom), as well as the report on the implementation, https://www.gbif.org/news/82812/licensing-milestone-for-data-access-in-gbiforg.

Ipomoea ID support from global expert, Alexis, based in Mexico

To be able to identify the Ipomoea members, there is a "trick", the important character is the sepals , the sepals are like fingerprints, and they are never repeated in any species of the genus in question.

On the other hand, many people believe that by observing the leaves or the color of the corollas, the species can be identified, but it is a mistake, there is no doubt that they help, but little, sometimes they complement, but being very variable they are not completely reliable.

Ipomoea triloba the sepals are scarious-margined, ciliate on midrib and margins, subequal, 5–6 (–10) mm long, oblong-mucronate or oblong-caudate. Small corola 1.5–2 (–2.5) cm long, campanulate, glabrous, pink; limb 1.3–1.6 cm diam

Corrected species cover photo

bouteloua shared: If you're positive something is identified as the incorrect taxon, you're actually able to correct it yourself. On the taxon page, if you click on "Curation" and then on "Edit photos," you should be able to remove the photo and then add a correctly identified photo if one is available.

Code for choosing specific genera


Code above is for the protected genera of Arachnids surveyed during CNC2023. See Journal entry.

the taxon_ids  numbers refer to the genera... Obtained using Explore feature: put name in species box and get number off the url. Place into  combined URL with a comma

Crotalaria dura subsp dura - Chales Stirton comments

David Styles did a useful summary distinguishing Crotalaria dura ssp dura and C. globifera. See https://www.ispotnature.org/communities/southern-africa/view/observation/486252/crotalaria-dura-subsp-dura

In essence he said quoting Marianne Le Roux:

Crotalaria dura subsp. dura has a prostrate, decumbent to decumbent-erect habit, whereas C. globifera has an erect habit.
Crotalaria dura subsp. dura has a keel petal that is rotund (U shaped) unlike the angled curvature and distally straight and elongate beak of C. globifera (looks like a medieval pointed shoe) (thanks to Marianne le Roux for this, included in an article previously published in PlantLife)
Note also the often brown calyces seen in Crotalaria dura subsp. dura.

Genus Aspalathus

As per Charles Stirton: If the keel is hairy then A. chortophila, if hairless then A. gerrardii. Unfortunately photos are not good enough for an ID.

Arachnid photo advice

Use manual focus
More macro shots
Focus as close to the phone as possible
Take the phone closer and closer to the subject and at about 12 cm distance it loses focus. Then move it back until the subject is in focus again.
