Campanula densiciliata Acharya Balkrishna, Harsh Singh, B.Joshi & R.K.Mishra sp. nov.

Diagnosis:— Campanula densiciliata shares similarities with C. argyrotricha, but it differs in sinuate leaves, rounded leaf base, reduced, crenate calyx teeth (less than half of the corolla), elliptic corolla lobes, and different lengths of stigmatic lobes (vs. dentate, crenate to serrate leaves, attenuate or cuneate base, entire calyx teeth half as long as corolla with entire or dentate margin and oblongoblanceolate to oblong-obovate corolla lobes, where stigmatic lobes are equally placed in C. argyrotricha. It is also similar to C. latifolia Linnaeus (1753: 165) but differs in ovate-elliptic, small (1.8–2.8 × 1.7–2.2 cm) leaves, solitary, terminal inflorescence, small flower c. 2.8 cm long, anther 1.4 mm long, stigmatic lobes with two different lengths (vs. lanceolate to ovate, large (12 × 7 cm) leaves, inflorescence on the axils of upper leaves forming a raceme, large flower 3–4 cm long, anther 8-11 mm long, same length stigmatic lobe).
  
Etymology:—The specific epithet ‘densiciliata’ is derived from its densely hairy margin of the calyx lobes.
