NILS SYLVEN, GENLISEEN UND UTRICULARIEN. 7 



nis der Kelchblätter erheblich kleineren, lateralen Blätter sitzen 

 nämlich in der Regel am Blütenstiele ungleich hoch befestigt und 

 sind gewöhnlich (mehr oder weniger deutlich) verschieden gross. 

 Ein Vergleich mit einer Art der australischen Gattung Polypoin- 

 pholyx (mit typisch vierzähligem Kelch) hebt unverkennbar die 

 Zusammengehörigkeit der hiesigen Art mit den reinen Utricula- 

 rien hervor. Schliesslich möchte ich hier auf die berechtigte 

 Kritik Oliver's von Benjamin verweisen: »Benjamin errs 

 in referring this plant {Utricularia longeciliata DC.) to the 

 Australian genus Polypompholyx, established by Lehmann 

 (Nov. stirp. Pugill. VIII, p. 48), the Tetralobus oi A. Be Ca^- 

 DOLLE (Prodr. VIII, p. 667). The calyx of Utricularia is 

 constantly diphyllous. In the true Poly pom pholyx, in addition 

 to the anterior and posterior calycine segments, common also 

 to Utricularia, we find a pair of opposite, lateral, and some- 

 what smaller lobes within the former. Minute lateral brac- 

 teoles with the usual subtending bract, as in numerous spe- 

 cies of the allied genus, are also found at the base of the 

 pedicel. It is upon the quadripartite calyx alone that the 

 genus depends; in other respects it is, I believe, quite a 

 Utricularia. — In U. longeciliata the lateral bracteoles, which 

 are rather largely developed, are not, as is usual, attached 

 immediately by the bract, but spring from the very short 

 pedicel at a small yet clearly marked interval beneath the 

 true calyx-segments, towards which they are, of course, late- 

 rally disposed. Benjamin has erroneously regarded these 

 bracteoles as forming part of the calyx, and indeed figures 

 them as such in the 'Flora Brasiliensis'. It is undoubtedly 

 a true Utricularia. A. De Candolle in describing the plant 



(Prodr. VIII, 23), expressly states, ' bracteolis 2 



majoribus flori adpressis;' and in the description of U. fim- 

 briata H. B. K. (Nov. Gen. et. Sp. II. 225), which I think 

 the same species, we also find a correct view has been taken 

 of these appendages: — 'Pedunculi basi instruct! bracteola 

 ovata dentato-ciliata adpressa. Bractese duae sub quoque 

 flore, oppositae, ovatae, dentato-ciliatae.' If an examination 

 of the specimens of Humboldt and Bonpland confirm this 

 presumed identity, their name must necessarily take prece- 

 dence.» (Oliver: Descriptions 1860, p. 171 — 72.) — Bei
