Is this a hairy plant or a glabrus one? Further in L. octovalvis the sepels are 0.5-1.2cm long petals are 0.6-1.8cm long whereas, in L. perennis it is less than 0.5 for both sepals and petals Please refer this http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=119063 and http://www.efloras.org/florataxon.aspx?flora_id=100&taxon_id=119063
If this is a glabrous plant with smaller flowers, I think this too is *L. perennis. * Regards, Giby On 21 October 2011 21:32, Satish Phadke <[email protected]> wrote: > I am not aware of the two species in detail.
