I also got the differences
I*pomoea dichroa
**I.** triloba*
Plant densely covered with white or yellowish hairs
Plant glabrous, nodes hairy
Leaves 5-13 cm long, 6-13 cm wide
Leaves 2.5-7 cm long, 2-6 cm wide
Leaves bristly-pubescent above, white-tomentose beneath Leaves
glabrous or sparsely pilose
Bracts 7 mm long
Bracts minute
Sepals bristly or setose
Sepals unequal, glabrous or sparsely pilose
Capsule ovoid, 8 mm long, pubescent above
Capsule globose, 5-6 mm, bristly pubescent, apiculate
Though the original plant identity is still elusive for me, Balkar ji's
plant is clearly I. dichroa (syn: I. arachnosperma; I. pilosa)
