A Call to Grass

Hi everyone,

I stumbled over this observation https://www.inaturalist.org/observations/28990168 of Cynosurus cristatus yesterday, which @bobwardell helped to identify. In checking the stats on the taxa page https://www.inaturalist.org/taxa/76581-Cynosurus-cristatus I found that we have only 12 observations in Germany so far, though wikipedia says it is a quite common grass, though locally listed as endangered. But looking at the GBIF data points in the map, it seems it should not be so difficult to get some more observations of it at iNat, though it seems to be advantageous to explore in Bavaria.

Digging a bit further in Poaceae it seems that many grass species are way too overlooked in general.

Poaceae observations in Germany: ~ 3000 observations with 161 different species sounds maybe not to bad. But a big chunk of them are not surprisingly Phragmites australis (266) and some others, and many, I assume, unidentified deeper than Poaceae:
https://www.inaturalist.org/observations?locale=de&place_id=7207&preferred_place_id=7207&subview=grid&taxon_id=47434&view=species

So I would like to give a Call to Grass for some of them (completely arbitrarily chosen ;-), their visuals seem catchy enough to remember them), which hopefully raises other Poaceae observation counters as well.
- Crested Dogstail (Wiesen-Kammgras), https://www.inaturalist.org/taxa/76581-Cynosurus-cristatus, currently 12 observations
- European Feather-grass (Echtes Federgras), https://www.inaturalist.org/taxa/355674-Stipa-pennata, currently 2 observations
- King Ranch bluestem (Finger-Bartgras), https://www.inaturalist.org/taxa/75842-Bothriochloa-ischaemum, currently 2 observations
- Blue Moor-grass (Kalk-Blaugras), https://www.inaturalist.org/taxa/363774-Sesleria-caerulea, currently 4 observations
- Giant Fescue (Riesen-Schwingel), https://www.inaturalist.org/taxa/162949-Festuca-gigantea, currently 11 observations
- Wood Millet (Waldhirse), https://www.inaturalist.org/taxa/165390-Milium-effusum, currently 18 observations

Any additions to the list, especially from a more expert point of view, are welcome!

Happy exploring!
Monika

I have some unidentified grasses. But no idea to identify them...

me two :-/ in the list I therefor tried to pick some that could at least be guessed, though expert confirmation would be needed

The first three I already found in Vienna. Cynosurus cristatus is even growing in front of my flat at a construction site :-)

Ha! :-) Yes, the documentation in Austria looks much better! 9 observations from a smaller country.

Hi Monika et. al. Had a think about your challenge and have a couple of thoughts - quality of photos!!!, number of photos!!! and diagnostic features!!! and common species that everyone should learn to start off with.
Do not submit rubbish photos!!
Focus focus focus!!
Photos of 1. habit 2. Panicle. 3. spikelet, 4. ligule, 5. culm, 6. sheath - ie. the diagnostic features - often need at least 3 to get a good chance of id.
Everyone should know these common species
- Lolium perenne
- Elymus repens
- Dactylis glomerata
- Poa annua
- Arrhenatherum elatius
- Holcus lanatus
- Phleum pratense

Cheers to you all and have a happy recording season for 2020 and do not forget - better photos!!!!

Hi Bob, many thanks for your motivational reminder to focus and helpful hints what is needed to ID grasses! I think we all, each time we are heading out, start aiming not to forget to document those diagnostic features (as fas as we know or assume them), but once out in nature it is not so easy not to loose focus – there is always so much other nature around :-)
Cheerful recording season to you as well!

here is an image from wikipedia regarding the mentioned diagnostic features:

This is very helpful -- thanks Bob for the useful hints what to look for and mobbini for the corresponding sketch. I don't know anything about grasses at all and had actually planned to change that for this year. So now I already know a little better what I should pay attention to :)

yeah! Looking forward to many grass observations with diagnostic features. And maybe by end of the year we can interprete some of them. :-)

@bobwardell can you have a look at this obs https://www.inaturalist.org/observations/40660413? Is it Sesleria caerulea?

Checked! should be much more records for central Germany http://www.floraweb.de/webkarten/karte.html?taxnr=23996

Thank you ... now they are 6, yes, there sure is still "air to the top" (How to translate "Luft nach oben"?)

Posted by mobbini 7 days ago (Flag)

'room to improvement' or 'room to the upside'? 🤓

Posted by carnifex 7 days ago (Flag)

room for improvement! please! hahaha!

Posted by bobwardell 7 days ago (Flag)

:-) well I will blend it a bit and take "air for improvement"

Posted by mobbini 7 days ago (Flag)

... thinking again at it, interesting, room & air is more similar than I got first, as "room" usually is filled with air

Posted by mobbini 7 days ago (Flag)

FYO - It is not a room in the sense of in a house, it is room (space/area) to move around in - although air still may play some strange part in that - Ha!

Posted by bobwardell 6 days ago (Flag)

I would argue that in this sense most "room" (space) is not filled with air. In the universe, that is.

Posted by jansson 6 days ago (Flag)

so we have room for vacuum then :-)

Posted by mobbini 6 days ago (Flag)
Thumb

... or space for vacuum ...

Posted by mobbini 6 days ago (Flag)

but that is OK for 'Raum' but not necessarily for a parking space 'Parkplatz'

Posted by bobwardell 6 days ago (Flag)

I see. ... english is so complicated^^ :)

Posted by mobbini 5 days ago (Flag)

You think that !- you should try to learn German ! HaHa!
