Cirsium falconeri from Kashmir-GS31122021-1

[Gurcharan Singh]

In a help to clarify our understanding of genus Cirsium, I am uploading my collection of Cirsium again.

Flora of British India had recorded following species under Cnicus, now Cirsium:  C. arvense, C. argyracanthum, C. involucratum, C.involucratum, C. falconeri, C. eriophoroides, C. griffithii, C. wallichii (with several varieties), C. sinensis.

BSI Flora of India had shifted C. arvense to Breea arvensis, but POWO considers C. arvense as accepted name; C. argyracanthum according to BSI Flora also includes C. wallichii var. wightii, C. involucratum is now C. verutum; C. griffithii of FBI is now C. interpositum; and C. sinensis now C. shansiense, 

BSI Flora gives Following Key:

1a. Inner involucral bracts with dilated tips

7. Cirsium wallichii

b. Inner involucral bracts not dilated at tips

2

2a. Heads usually ca 2.5 cm across

3

b. Heads usually 3.5-7.5 cm across

4

3a. Leaves always glabrous above; heads densely fascicled

1. Cirsium argyracanthum

b. Leaves ciliate smooth or scaberulous above; heads usually solitary

5. Cirsium shansiense

4a. Involucral bracts quite glabrous, none really spinescent, the points of the outennost being merely needle-like; pappus ca 2.5 cm long

4. Cirsium interpositum

b. Involucral bracts not quite glabrous, ending usually in spines; pappus ca 1.5 cm long

5

5a. Corolla usually ca 6 cm long

2. Cirsium eriophoroides

b. Corolla usually ca 2.5 cm long

6

6a. Heads densely woolly, subsolitary, drooping

3. Cirsium falconeri
