| For the group of plants treated in the “Compendium” I have used the name Spermatophyta. WETTSTEIN in his “Handbuch” remarks that this name is incorrect because in botany the word “sperma” is used for spermatozoids, and from the name Spermatophyta it might be concluded that by it “plants with spermatozoids” were meant. WETTSTEIN’s objection is not to be taken seriously however. Nobody will ever think of translating the name Gymnospermae by “plants with naked spermatozoids”! I did not like to use the name Phanerogamae for the group since the corresponding name “Cryptogamae” has lost all meaning. “Anthophyta” cannot be used, because the Pteridospermae have no flowers and it would even be advisable to use the term “Flower” only with regard to Angiospermae.

| A new species of Paullinia, viz. P. Bernhardi Uitt. was described on p. 774 of the last volume of this periodical. I have to add here another new species to this formerly monotypic section Cryptoptilon. The three species now known are all collected uncompletly. The flowers of the two Suriname ones are wanting; those of P. verrucosa Radlk. from British Guiana are known, but unfortunately only rather young fruits are found. A new diagnosis of this section is given here together with a key and the description of the new species. Sect. Cryptoptilon Radlk. in Engl. u. Prantl, Nat. Pfl. fam. III, 5 (1895), p. 304, fig. 156 IX; id., Monogr. Paull. (1895—96), p. 247, fig. 9; id. in Engler, Pflanzenreich IV, 165, p. 309 (1931). |

| In my revision of the Turneraceae for PULLE’s Flora of Suriname, I have accepted the genera Piriqueta and Turnera in the delimitation given to them by URBAN. The distinction rests on the presence in Piriqueta of a “corona” at the insertion of the petals. This corona, however, is often so weakly developed as to be almost invisible, and as moreover, the African representatives of Piriqueta appear to be more easily distinguishable from the American ones than the latter from some of the Turneras, the taxonomic importance of this organ appears to be somewhat dubious. A decision of the question, however, would necessitate a more extensive study of the genera than the demands of the present revision would justify; owing to lack of material, moreover, such a study... |
