Androsace muscoidea in FOI

[J.M. Garg]

Hi, Tabish ji,
Images by Thingnam ji of Androsace muscoidea in FOI look different from those at Androsace muscoidea Duby and as per Androsace world.

It may be Androsace globifera as per images in Androsace world:

Pl. check.

Thank you Garg ji,

  I think you are right that it is not  Androsace muscoidea. However, I don't think it is A. globifera, as the images don't quite agree, and A. globifera is found in Eastern Himalayas, and not in Ladakh. I think this plant is Androsace villosa. Compare with the images at POWO. I am attaching higher resolution images. The calyx particularly agrees. Compare with images here too:

Thanks, Tabish ji.

There is a real confusion over here.

I could not find Androsace villosa, though distribution is given in POWO and CoL.

Flora of Pakistan gives Androsace robusta ssp. robusta (Androsace jacquemontii var. robusta (R.Knuth) Govaerts in POWO). It says:
The ssp. robusta differs from the European Androsace villosa in its robust habit and with larger plant parts. .................... 
The species Androsace robusta has also been confused with and included in Androsace muscoidea by several authors (Handel-Mazzetti 1927, p. 163 and Gould 1982). The two taxa are quite distinct not only morphologically but also occupy to a greater extent different areas.

Also see A.villosa and A.robusta in Androsace World.

Here are keys from Flora of Pakistan:

18 (17)	Leaf rosettes 3-6 mm broad, globose. Leaves ± incurved, 2.1-4.5 x 1.1-1.5 mm. Scape up to 8 mm long, 1-2-flowered		16 Androsace muscoidea
+	Leaf rosettes loose or if globose then 4-14 mm broad. Leaves not incurved, 3-11 x 1-2.8 mm. Scape (5-) 7-90 mm long, 3-12-flowered		(19)
19 (18)	Plants robust. Leaves densely appressed villous, cinerascent green or silky white		(20)
+	Plants of a ± slender habit. Leaves sub-glabrous to pubescent-villous, but not densely so		(21)
20 (19)	Rhizome woody, c. 4.5 mm thick. Scape up to 10 mm long. Seed with a prominent hilum scar		11 Androsace villosissima
+	Rhizome and seed not as above. Scape 40-95 mm		10 Androsace robusta

After going through all this I am also leaning towards Androsace villosa.

Dear Garg ji,

  Long back you had expressed surprise that although Androsace villosa, showed distribution in W Himalaya, it did not figure in Flora of Pakistan. I found out, what figures in W Himalaya is Androsace villosa var. robusta  which is a synonym of Androsace jacquemontii var. robusta, the currently accepted name. Androsace robusta which is considered by FOP is a synonym of Androsace jacquemontii var. robusta. Androsace robusta is also listed in Klimes & Dickore's Ladakh checklist. I think this solves the mystery.

Thanks, Tabish ji.

But I find it more closer to Androsace villosa (as per Androsace World) rather than Androsace jacquemontii var. robusta (R.Knuth) Govaerts (as per FOP illustration and Androsace World)

POWO gives its distribution in the West Himalayas.
