Flowers larger, with corollas more than 2cm long. 2.Stipules 3-fid or torn; Leaves narrowly lanceolate; stigmas with 2 short obtuse lobes ...................................................... 1.L. wallichii 2.Stipules entire; leaves obovate to elliptic; stigmas with 2 slender elongate lobes ......................................................... 2.
