Sharing some pictures for ID shot at Gund Bhaktapur Nepal on 11 September 2016 at 5100 ft.


Orobanchaceae member ? Striga species ?


I guess it is matching with Striga angustifolia (D. Don) C. J. Saldanha based on flower, color of flower, stem and altitude as per eflora Nepal.


Request for further validation whether it is S. angustifolia or S. masuria.


Do you have images of the habit ?

Adding some pictures but not so clear. Attachments (4)


If we follow the Flora of China keys, it should be Striga densiflora (which gives its distribution in China, India, Sikkim)
But it is not given in the checklist of Nepal.

I went to the spot again yesterday and shot some pictures which I believe would support for correct ID. Attachments (6)


The calyx is 15-ribbed and the lobes are as long as the tube. So, this should be Striga angustifolia.


Pl. have a look at these images- these look different from the images you commented upon.


I guess it is matching with Striga angustifolia (D. Don) Saldanha.
Other 3 listed in Nepal does not match.

I feel it is slight difference from S. densiflora and S. angustifloia.
Different images are found for the same sp. in the web.
Could some one verify with the images of herbarium ?

You have to go through the keys in FOC and decide.

Thank you …! It is Striga  but I could not come to the conclusion

as earlier in this case.


Pl. follow the keys in FOC.

Plant for ID: (mixed thread): 4 correct image as above (2nd set)
I photographed this plant today at my farm near BandhavgarhPlant height is about 20 cm flowers across about 2 cm.
May I request to help in ID please.

Striga densiflora
Orobanchaceae; earlier Scrophulariaceae.
Root parasite on some grasses

Yes This is striga densiflora


I think this is Striga angustifolia.
The first picture shows 3 nerves per calyx lobe (to be verified), totaling 15 nerves thus qualifying to be S. angustifolia.
http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=131731
In S. densiflora, the calyx is totally 5-nerved, 1 per lobe, as seen here.

… would say, “look at calyx”
I ask for habit and wide view as well.
3 ribs per calyx lobe makes it Striga angustifolia.
Beautiful images…… nice portray of characters.


agree with … and hence now with … good pictures

Striga ¿ densiflora / angustifolia ? … also placed in Orobanchaceae
at Pateshwar near Satara on 08 SEP 12

The calyx is 15-ribbed. So, this should be Striga angustifolia as per keys at Flora of China


I guess correct …!

DV :: 08 SEP 12 – 0256 :: Striga ¿ densiflora / angustifolia ? at Pateshwar:  Pateshwar in Satara about 2700 – 3300 ft asl
Date & time: September 8, 2012 at 2.56pm
Habitat: hill with semi-evergreen forest
Habit: herb about 20 cm high, flower 5 – 6 mm across
… the first among photos below is cropped to get closer to the flower – to see the calyx lobe.
Not sure if this is single-veined OR three-veined calyx lobe.

I think Striga densiflora 


The calyx is 15-ribbed and the calyx lobes are almost as long as the corolla tube. So, this should be Striga angustifolia as per keys at Flora of China


Looks like S. angustifolia!


Thank you very much for this validation, …, will revise my notes at flickr.

Habit image of the plant


Among the Striga species having distribution in Himanchal Pradesh it loks matching to Striga angustifolia (D.Don) Saldanha .


It is difficult to check the details on enlarging.
Clear and detailed view of calyx is required for id as per Keys at Flora of China

Attaching one more image where close up of calyx is visible. May be it helps in identification.
1 image.

I too agree with … for angustifolia

Malhargad near Pune, MH :: Striga for ID :: ARK2021-045: 4 images.

Saw this Striga species at Malhargad near Pune in July 2021 on a small hillock.
The flowers here were larger than Striga asiatica.
Requested to please provide ID.


Please check Striga densiflora (Benth.) Benth. !


I am confused between S. densiflora and S. angustifolia.
Let us wait for further comments.


Pl. post high res. images to check the details of corolla tube and calyx.


Unfortunately, these are the only pics I have, am attaching a close up of the pics, if that would help.
3 close up images.


Let us keep it as Striga angustifolia (D. Don) C.J. Saldanha for the time being as per comparative images and details at Striga, as I see 15 ribbed calyx in the 3rd image.


Let us keep it as S. angustifolia.
