ID of Boraginaceae member is requested

[taffa...@gmail.com]

Dear members,

Am attaching photos of a Boraginaceae family plant growing in a field in Srinagar.

Habitat: wild

Habit: Herb. Weak erect stems branched at bottom in some plants. Height 30-40cm .Stems  rough and clinging due to minute transparent thorn like structures pointing downwards (See photo). Flowers 3mm in diameter, Corolla blue with a magenta ring at base surrounding the faucal appendages (See Photo).

Kindly help me to ID this herb.

With regards

Taffazull

However it appears very different from the photo on FOI page https://www.flowersofindia.net/catalog/slides/Purple%20Forget-Me-Not.html.

Flowers are blue and not purple, there is a magenta ring at base of corolla  and petals are just 1-1.5mm long. Also faucal scales seem to be very different  from that in FOI photo.

Some more photos:

Photo1 shows flower held between fingers to compare with similar photo of C.microglochin by  Tabish Ji on FOI website. The difference in the size of the flowers is easily seen.

Photo 2 Magnified view of one of the biggest flowers on the herb. Each small square of the graph paper in the background is 1mm.

Photo3 Magnified view of Faucal appendages. 5  pairs can  be seen.

Photo4  Corolla removed to show 2mm long sepals. The lanceolate sepals seem to be different from the sepals in FOI photo. The short style is also visible.

I may also point out that the stem rather than being hairy has hook like spines projecting downwards which make the stem have a rough and clinging feel.

Thanks to Mahadeswara ji for link to FOI page.

On FOI page it is mentioned as occurring only above 2000m but Srinagar (Rawathpora) is only 1600 meters asl so the info needs to be corrected.

Am attaching some more photos.

Photo 1 is of a Maple Leaf like structure. Photo 2 is detail of same. According to NatureGate https://luontoportti.com/en/t/1832/madwort 

"Madwort spreads well: due to its hooked tips the calyx, which resembles a miniscule maple leaf and envelopes the ripening mericarps, is very adhesive."

Photo 3 shows corolla  and a calyx lobe(2mm). Corolla has  1mm lobes and a 1mm corolla tube expanded in the middle. Five pale yellow anthers (not visible in photo) are adnate to and inserted in the corolla tube.

Photo 4 is  of tiny round pollen grains (X675). These are the smallest pollen grains I have seen so far in my very limited experience of looking at pollen grains of different plants as a hobby and a pastime.

I wonder if this is a European species which has become invasive just like Conyza canadensis which is so common here that it has even got a vernacular name.

Regards

Taffazull

Actually the pollen grains are round in polar view but rather dumbbell shaped in equatorial view as is apparent from the photo.

An Interesting Fact
Stewart in his book Flora of West Pakistan.. has mentioned that  Asperugo procumbens is the only member of the Boraginaceae family in the region which has a trailing habit.

A photo of a long trailing plant is attached

Yes, appears close to images at
