Dear members
I had uploaded this plant from Uri Kashmir in July 2010
https://groups.google.com/forum/?fromgroups=#!searchin/indiantreepix/Anagallis$20foemina/indiantreepix/G0FbcUqqk7k/W9jCbnqZN_AJ

 In light of my mail in the group Dec. 21, 2011 my plant from Kashmir
should be *Anagallis arvensis* var. *coerulea* (L.) Gouan, Fl. Monsp. 2930.
1765., and not subsp. foemina which is now treated as a distinct species
and is a distinct plant as per a a recent study:

Manns, Ulrika; Anderberg, Arne A. (2007). "Relationships of *Anagallis
foemina* and *Anagallis arvensis* (Myrsinaceae): new insights inferred from
DNA sequence data". *Molecular Phylogenetics and
Evolution<http://en.wikipedia.org/wiki/Molecular_Phylogenetics_and_Evolution>
* *45* (3): 971–980.

I am reproducing below the details of my earlier mail:

The common pimpernel has confused both field workers and reputed authors
alike, but luckily the confusion seems to have been resolved more recently.
Carolus Linnaeus, the Father of Taxonomy described two closely related
species of Anagallis:
*Anagallis arvensis* L., the scarlet pimpernel with orange-scarlet to
scarlet flowers
*Anagallis caerulea* L., the blue pimpernel with blue flowers

The two are now treated as two varieties var. arvensis and var. caerulea
(L.) Gouan of Anagallis arvensis L.

Schreber, Spic. Fl. Lips. 5 1771 described a related species Anagallis
coerulea (note slight difference in spellings), also used by Lamarck, a
taxon that had been long treated as same var. caerulea of A. arvensis. It
was only in 1972 that Fergussen established it to be a synonym of a
distinct species Anagallis foemina Miller (1768). The plant List treats
this as Anagallis arvensis subsp. foemina (Mill.) Schinz & Thell. Important
to note that this taxon always has blue flowers. This is how the two
species can be differentiated:

*Anagallis arvensis
        Anagallis foemina*
1. Flowers scarlet (var. arvensis) or blue (var. caerulea)   1. Flowers blue
2. Pedicel in flower longer than subtending leaf.                2. Pedicel
in flower shorter or equal to the subtending

                    leaf.
3. Sepals shorter than petals especially in bud                  3. Sepals
equalling or longer than petals especially in

                    bud
4. Petal margins overlapping
 4. Petal margins not overlapping
5. Petal margins with numerous hairs tipped with               5. Petal
margins with few or no hairs, which if present
    globose glands
          have elongate terminal cells.

Let us look for our blue pimpernel (blue flowered Anagallis) more closely
in light of above information to find its exact identity. Who knows we may
have both taxa in India.
