I think I was mistaken because of small size of inflorescence.
Under a magnifying glass the inflorescence appears scorpoid (See photo INFLORESCENSE X15)
Wonder if it could be C.wallichii (Native of Nepal)
The following points regarding it given by Kazmi seem interesting " Inflorescence terminal or axillary, usually geminate branches divaricate , ebracteate , short scorpoid , bearing closely set flowers, much elongated after flowering, pedicils none to very short in flower..upto 3mm in fruit, ..Corolla pale to deep blue ,campanulate, 3.5-4mm long , tube equalling the calyx , limbs equalling the tube , divided nearly to the base , lobes rounded, faucal appendages subquadrate , slightly emarginate.."
