Novitates Taxonomicae II, ex Herbario Academiae Rheno-Traiectinae

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 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. Pauli. (1895—96), p. 247, fig. 9; id. in Engler, Pflanzenreich IV, 165, p. 309 (1931).
