form the at last of the somewhat outer, deciduous, margin cupule, below the top-margin. The outer staminodes, pressed against and the partially in stamens, are at first sessile, after flowering they

become more slender and incurved. The basal glands, at first free pressed together grow out to tepalous, sub-stipitate, appen- dages of the filaments after flowering. In well-developed flowers

the anther cells are distinctly introrse, but by lack of room or by compression, they often give the impression of being apical, the insertion of the the of the cells even extrorse; valves at top real may give evidence of the position of the cells. 734

Meissner described 2 specimens as Goeppertia geminiflora and Guillemin Martin 45 (French Guiana) 231 (Brasil, Corcovado).

The description corresponds most with the specimen Guillemin which therefore consider the of his 231, I type specimen species. The Martin is the of the specimen 43 type specimen genus Syste- the of of this monodaphne Mez; name the only species genus should therefore be altered and I to it the propose give name: The of Systemonodaphne Mezii Kosterm. nom. nov. fruiting part 757

of herbarium the specimen Pohl in the Brussels in my opinion belongs to a different species: the leaves are prominulous-reticulate the surface. on upper Laurus geminiflora Desvaux in Hamilt., Prodr. Fl. Ind. occ. the (1825), p. 37 does, according to description, not correspond either with Phyllostemonodaphne or with Systemonodaphne.
