Urtica ardens/ABDEC10

[Ashwini Bhatia]

New shoots are coming out on our ubiquitous nettle. I took some close ups today to show the translucent white bristles on leaves and the stalks. This pretty plant can give a painful sting and all of us here have some time or the other been victim of our occasional carelessness.

There are these caterpillar like protrusions on the Urtica ardens plants. What are they for I wonder.

Thanks.

[Ushadi Micromini]

its a fungus called rust

affects stems

here its done the stem of the leaf in...

usually seen on u dioica...see this figure
 Fig 5. Rust of stinging nettle (Urtica dioica) caused by Puccinia caricina.

its about 70% down the page

but dont see why it cant infect u ardens.

secondly be very careful of the stings

all nettles nettle

so beware

wear gloves and use tweezers and forceps if you have to touch them

as in removing them from your yard etc

These nettles are flowering now and I have photos of the male and female flowers. Please advise if I am wrong. First, following Dr Gurcharan Singh’s ID key, I checked the stipules on dozens of plants to make sure that the plants we have here are Urtica ardens. They are indeed so. I did not see a single U. dioica plant on our slopes.

Here are the photographs taken between 28 and 30 June.

Thanks.

Ashwini ji 

I am afraid you may not have mixed up your plants.

Urtica dioica is distinct in free stipules, male and female flowers usually on different plants, profuse stinging hairs

https://groups.google.com/forum/#!searchin/indiantreepix/Urtica$20dioica/indiantreepix/dZQk7CZJzHg/fbMKyTIG0pgJ

Those with connate stipules we should look for two types of plants 

U. ardens with profuse stinging hairs, blistered and uneven surface so that it becomes wrinkled when dry, stipules mostly rounded at tip

https://groups.google.com/forum/#!searchin/indiantreepix/Urtica$20ardens/indiantreepix/evkPChbsAQ8/4K4d8YCeSpgJ

I will upload another population of U. ardens soon

U. parviflora with few stinging hairs, narrower leaves, smooth leaf surface and stipules bifid at tip

[Ashwini Bhatia]

Thank you Dr Singh once again. I might be mixing up U. ardens with U. parviflora. Do you think the sample with female flowers is U. parviflora? Please see these photos of the same branch; In the second photo, one stipule looks bifid but the other does not. Almost all the stipules in both male and female plants are not rounded.

Please advise. If you advise I could do another set of photos or collect a few stipules for a closer look.

Thanks and regards,

Ashwini

Additional photos of the plants with male flowers growing next to each other;

[Gurcharan Singh]

Your fourth photograph in fresh photograph looks different with smooth surface (not blisted, which can be clearly seen in other photographs with rounded stipule tip) it may be be U. parviflora.

    Having said that we must be prepared with some variation, because almost all authors have been confusing between the two.

Thank you Dr Singh for taking the time. I am grateful. I think the best way forward would be for me to find individual plants with easily accessible stipules and flowers and make a case study out of it with the leaves, stems and hair. I will try and do so in the coming days and post the results.

Regards,

Ashwini

Two days back I photographed a hairy nettle plant thinking it to be U. ardens but when I looked closely at the stipule it turned out to be the U. parviflora. Please check and advise.

All the photos are of the same plant. 

Thanks.

Ashwini

[JM Garg]

Taking it as Urtica himalayensis Kunth & Bouché (syn: Urtica mairei var. oblongifolia C.J.Chen; Urtica zayuensis C.J.Chen) as per discussions at A relook at our specimens of Urtica parviflora.

Thanks, Tabish ji, for pointing out. 

[Gurcharan Singh]

Yes Garg ji.
