Aeschynomene aspera, L. var. OLiGARTiiRA, F. V. M., Herb. 



(Legumino-sae). Port Darwin, M. Holtze, 1891. 



This plant was originally considered by von Mueller to be a 

 new species, but was subsequently referred by him to A. aspera, 

 Linn., to which it undoubtedly belongs. It differs in the fruit 

 having only 1 to 3 rather large segments, each usually 1 cm. 

 broad by 1^ cm. long, and with nearly smooth side walls, whereas 

 those of the type species are usually covered with warts or 

 papillae, and are 7 to 8 mm. Ijroad by 8 to 10 nmi. long. Fruits 

 of a few segments appear also on the type species, and in such 

 cases the segments tend to become larger than in the longer pods. 

 The variety is, however, a strongly marked one, and apparently 

 hitherto unrecorded. A. aspera is new to Austi'alia. The stems 

 of the plants are used by the Chinese for making paper, and it is 

 just possible that the plant may have been introduced by them. 



Albizzia (Archidendron) pentzkeana, F. v. M., Herb. 

 (Leguminosae) — A. vaillantii, F. v. M. Fragm., v. 60, 

 variety Pentzkeana. 



A number of specimens of the apparently unpublished species 

 A. pentzkeana were found at the Herbarium. A specimen 

 submitted to Kew was marked by Dr. Stapf "genus correct, 

 species unpublished." 



Close comparison with A. vaillantii, however, reveals so many 

 features in common that the plant can only be classed as a 

 variety of that species, differing chiefly in the shape and large
