The difference between Calanthe discolor and Rhododendron

Stem Division: the pseudobulbs of shrimps are relatively thick and short, and the shape is conical; the pseudobulbs of Rhododendron are ovoid or nearly spherical, and the length is 1.5 to 3 cm. Leaf differentiation: the shape of shrimps'ridgellan leaves is oblong; the shape of Rhododendron's leaves is narrow ellipse. Flower differentiation: the former has shorter scape length, with short hair distributed; the latter has longer scape.

I. difference of stem

The rhizome of shrimps is not obvious. The pseudobulb is relatively thick and short. Its shape is cone-shaped and its diameter is about 1 cm.

Pseudobulbs of Rhododendron are ovoid or subglobose in shape, 1.5 to 3 cm in length and 1 to 3 cm in diameter.

2. The difference of leaves

The shape of the shrimps is oblong, about 25 cm in length and 4 to 9 cm in width.

Rhododendron leaves are narrow elliptic in shape, about 18 to 34 cm in length and 5 to 8 cm in width.

The difference of flowers

The length of scapes is shorter, about 18 to 30 cm, densely distributed with short hairs, and the length of racemes is about 6 to 8 cm.

The scape of Rhododendron is relatively erect and long, about 27 to 70 cm, and the raceme grows about 10 to 25 cm.
