Gynoeceums und mit Rücksicht auf die Mehrsamigkeit der Karpiden; 

 ferner sind die Samen der Neuradoideen wie die der Pomoideen 

 apotrop und die Samenanlage mit 2 freien Integumenten versehen. 

 Schliesslich scheinen die Neuradoideen neben den Pomoideen die 

 einzigen Rosaceen zu sein, bei denen Reste des Nucellusgewebes 

 in dem entwickelten Samen zurückbleiben. Durch das Fehlen eines 

 Obturators und die Abwesenheit des Endosperms im reifen Samen 

 weichen jedoch die Neuradoideen auch von den Pomoideen ab. 

 Jene sind daher nach Verf. am besten als eine der Hauptabteilungen 

 der Rosaceen-Familie aufzuführen. Wahrscheinlich repräsentieren 

 sie einen Typus von hohem Alter. Grevillius (Kempen a. Rh.).

89—92. 1916.) 



This remarkable climbing shrub described by Baillon as D. 

 Tholloni, was originally discovered by M. Thollon in the Niari 

 district, French Congo, and was not found again tili 1914, when 

 flowerless shoots were received from Sierra Leone. A descrip- 

 tion and hgure are given in the hope that further material of 

 Dioncophylluni may be received. 



In discussing the morphological interpretation of the peculiar, 

 hooked leaves the author inclines to the view that the leaf is Com- 

 pound, the apparent lamina being regarded as a winged petiole, 

 the hooks as representing lateral leaflets and the apical cusp as a 

 terminal leaflet or a reduced rhachis. 



The systematic position of the plant being uncertain, an exa- 

 mination of the anatomical characters of stem and leaf was also 

 undertaken by Miss F. M. Scott. No certain evidence was obtained, 

 but the presence of cortical bundles and internal phloem afford 

 some confirmation of the view that the genus is referable to the 

 Passißorales. Fruit and seed of this plant are at present unknown, 

 when described they will probably shed light on its affinities.
