Abstract
Radula javanica Gottsche et al. (1845: 257) was described with many syntypes. Castle (1966) lectotypified it with a specimen from Caroline Islands. This is appropriate in spite of the name indicating it is from Java as it is the only syntype that bears perianths and these were described in the protologue. The plant in Castle’s lectotype turns out to be the same entity as Radula cordiloba Taylor (1846: 375) which was, we believe correctly, synonymized with R. javanica by So (2005).
