Help ID the Lactuca species

[taffa...@gmail.com]

Dear Members,

Please help identify the Lactuca species which differs from L.serriola in not having spines on the veins and leaves that are entire and not pinnatifid.

Habitat: Field in Rawathpora

Habit: Herb about 1.5 meters high

Leaves: Sessile and not pinnatifid like L.serriola

A google image search turned up L.indica as a possibility. Would request opinion of experts on the same.

Regards

Outer phyllary is 3mm ,middle about 5mm and inner about 7mm

I think L. serriola only, leaves can be undivided sometimes

Dear Gucharan ji,

Thanks for ID

It is interesting that not only leaves are undivided but spines on  midrib are also absent.

I was under the misconception that spines on midrib are a characteristic of L .serriola.

Thanks for clarifying

Regards

Sorry Taffazul ji, I thought there are prickles on the midrib, 

Look for Lactuca sativa, the wild form.

Dear Gurcharan Ji,

Thanks for clarifying

According to a local villager Mr.Anwar its Kashmiri name is Doodich Ghas  literally meaning grass with milk.

This is exactly what Lactuca  means in Latin.

Sorry Taffazul ji, I thought veins are prickly beneath

Please look for these characters

1. leaves entire or rarely toothed, less than 1 cm broad in L. indica, at least lower runcinate-pinnatifid with spinulose margin and midrib beneath in L. serriola

2. Leaves not clasping or weekly clasping at base L. indica, distinctly clasping in L. serriola

3. Achene beak less than 2 mm long L. indica, 3.5-5 mm long in L. serriola

4. Achene bodyl winged with one prominent rib on either side in L. indica, not winged with 7-9 ribs on either side in L. serriola

If it really turns out to be L. indica, It may be a new Record for Kashmir, the species occurs between 

Please compare with these links

and for serriola

https://efloraindia.bsi.gov.in/eFlora/taxonList.action?id=6258&type=4

Please note that L. indica looks very similar to L. dolichophylla (syn: L. longifolia DC of FBI) in which florets are blue and also as FBI writes:

  Habit of L. Iongifolia and as tall, but the leaves are never pinnatifid and want the sagittate base ; the achenes are quite different, very flat, black, \ in. long, includ ing the beak, with one strong median rib on each face and 4 more slender lateral ones on each side of the dorsal face; the base of the beak is black in this (white in Ionat' J'olia); the pappus is dirty-white or yellowish. Ligules pale yellow within, purplish outside in Assam (Griffith), sulphur yellow in China (Ilance in litt.).

Wish you best of luck

I had written you privately but did not get response. I wanter to know if you have done Botany M.Sc. from Kashmir University, and if so need your WhatsApp number to add you to our Alumni Group.

In view of the detailed discussions and descriptions in eFloras, I think it should be Lactuca indica only.
