HOLOTYPE. — Pierre 4412 (B, destroyed).

LECTOTYPE. — Pierre 4412 (P), Vietnam, Dông Nai, designated here .

Beentje, Meded. Landb. Wag. 82-4: 151 (1982) designated a P specimen of Pierre 4412 as a lectotype. However, only one specimen was found at P which had been labelled isotype by BEENTJE. Therefore, the new designation here should stand unless the specimen marked as lectotype by BEENTJE can be located.
