A species of Licaria which superficially resembles the members of the Ocotea 

 caudata complex. It is separated at once, however, on examination of the flowers 

 which show the structure typical of Licaria. The species varies from the norm 

 in having a very slender gynoecium, perhaps because the particular specimen was 

 collected in young fruit and more than usual pressure exerted by the connate 

 tube — a fact borne out by the difficulty experienced in dissecting the very tightly 

 adhering staminal column from the style. The slender gynoecium resembles in 

 appearance abortive structures in some staminate flowers of Ocotea. The relation- 

 ship within the genus is not easily ascertained. Possibly the affinity lies with L. 

 vernicosa (Mez) Kostermans of which I have seen only a photograph of the type.
