This has incorrectly been identified as *Myosotis laxa* subsp. caespitosa*.* Dr Singh was correct to draw attention to the spreading hairs on calyx which rules out this species (or *M.palustris*) if you accept this species in India. *And that the choice appeared to be between M.sylvatica and M.arvensis.*
The next part of the key to the genus is a problem because it refers to the length of the pedicels compared to the fruiting calyx - the final image shows an immature fruit. After that other features of the fruits such as nutlet characteristics are important and width of corolla limb - the latter is difficult to estimate from the photo then because it is a cultivated plant of no known provenance, one cannot use that information to help..... Nevertheless, *M.stricta* and *M.refracta* (which is not an accepted name in 'The Plant List') can be eliminated. *So how does no tell M.sylvatica and M.arvensis apart? We have both species in the UK. The key in 'The New Flora of the British Isles'. In M.sylvatica the corolla is less than or equal to 8mm across, with a +/- flat limb; calyx teeth erecto-patent exposing ripe nutlets whereas M.arvensis has a corolla less than or equal to 5mm across, with saucer-shaped limb, calyx teeth erect +/- appressed and concealing ripe nutlets). But do these descriptions apply to specimens in India?* *Of the two I am favouring M.arvensis see: http://www.naturespot.org.uk/species/field-forget-me-not <http://www.naturespot.org.uk/species/field-forget-me-not>* *rather than M.sylvatica see: http://www.naturespot.org.uk/species/wood-forget-me-not <http://www.naturespot.org.uk/species/wood-forget-me-not>* *Professor Stace considers maximum corolla-size is of diagnostic value in Myosotis but larger flowered spp. often produce flowers with unusually small corollas.* *What do you think - either way, definitely not M.laxa subsp. caespitosa.... * On Saturday, June 9, 2012 at 3:08:10 PM UTC+1, Gurcharan Singh wrote: > This is another Myosotis which is grown in Herbal Garden in Kashmir, I am > inclined to include under Myotosis syklvatica (or M. arvensis) because of > spreading hairs on calyx, calyx loles spreading in flowers, erect in fruit > and acute nutlets, but appressed hairs on stem and inflorescence axis are > puxzzling, Please help in resolving. > > > > -- > Dr. Gurcharan Singh > Retired Associate Professor > SGTB Khalsa College, University of Delhi, Delhi-110007 > Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018. > Phone: 011-25518297 Mob: 9810359089 > http://www.gurcharanfamily.com/ > http://people.du.ac.in/~singhg45/ > > -- You received this message because you are subscribed to the Google Groups "efloraofindia" group.
