Senecio sp. for identification (Jacobaea analoga ?) - YS Apr2020/01

[Yogesh Sharma]

Respected all,

Please help to identify this Senecio sp. It looks similar to Jacobaea analoga (DC.) Veldkamp (syn.- Senecio laetus Edgew. & S. chrysanthemoides DC., according to 'Catalogue of Life').

Another match is Jacobaea raphanifolia (Wall. ex DC.) B.Nord. (syn.- Senecio raphanifolius Wall. ex DC.).

Date of Photo - 28th Sept., 2019

Place - Jalori Pass, Himachal Pradesh.

Regards,

Yogesh Sharma

Thanks, Yogesh ji, for the wonderful presentation.
What was the altitude?

Yes, two appears to be quite close.

Flora of China give the following keys:

79 (78)	Capitula large, involucres 5-7 × 8-15 mm; ray lamina 9-12 mm		(80)
+	Capitula small, involucres 3-6 × 3-7 mm; ray lamina 4.5-9 mm		(82)
80 (79)	Pappus reddish brown, scant in ray florets, 4-5 mm.		46 S. raphanifolius
+	Pappus white, abundant on all florets, ca. 6 mm		(81)
81 (80)	Bracts of calyculus 10-12; ray lamina ca. 9 mm.		43 S. multibracteolatus
+	Bracts of calyculus 2-6; ray lamina ca. 12 mm.		49 S. ambraceus
82 (79)	Basal and lower stem leaves lyrate, with comparatively large, broad, dentate terminal lobes.		44 S. analogus
+	Basal and lower stem leaves pinnatisect, with small, narrow terminal lobes		(83)

Keys in Flora of Bhutan :

6. lnvolucre 5-10mm diameter; phyllaries 5-7.5mm: ligules 7-12 >< 2-4.5mm; pappus reddish. absent from ray flowers or reduced and caducous …. 4. S. raphanifolius (syn. of Jacobaea raphanifolia (Wall. ex DC.) B.Nord.)

+ lnvolucre 3.5- 5mm diameter: phyllaries 3.5-5mm: ligules 4—7 >< l.5—2.5mm: pappus whitish or reddish. usually present and unreduced on ray flowers . . . . .. 5. S. laetus (syn. of Jacobaea analoga (DC.) Veldkamp syn. Senecio chrysanthemoides DC.)

Pl. also see FoC illustration.

Pl. check.

However, Flora of China gives distribution as Bhutan, China, NE India, N Myanmar, Nepal for Senecio raphanifolius Wallich ex Candolle as also Annotated checklist of Flowering plants of Nepal 

[Yogesh Sharma]

Thankyou Garg sir, for providing the key. I have checked the key and illustration. I think images only are unsatisfactory as I can not measure the size of floral parts. But as I tried some estimation for involucre size and illustration on FOC, it looks more like S. raphanifolius, but distributions provided by FOC restricts it only to NE India and S. analogus has NW India in its distributional records.
So this all seems unsatisfactory, chances are likely to be S. raphanifolius.

Yogesh Sharma

Any further views, Yogesh ji ?

[Yogesh Sharma]

Sir, though I cannot follow the key provided by you from FOC, as I can't measure size of the parts required, it could be J. analoga according to the distributional status provided by FOC.
Further investigation needed sir, either size measurement or any literature which shows if J. raphanifolia is reported from NW India.

[J.M. Garg]

I think may be Senecio chrysanthemoides DC. only as per GBIF

Also see Senecio raphanifolius Wall. ex DC. as per GBIF
