AND GENERA OF PLANTS. 453 



Islands, with diffusely trailing, oppositely branching-, quadrangular stems, 

 and opposite, pseudobipinnate leaves. Flowers yellow, usually terminal in 

 threes, nearly sessile. — (The name from cfx'-^^i ^o dissect, an^ ^vX?iOv, a leaf; 

 the leaves being remarkably dissected.) 



Schizophyllum * micranthum. 



Hab. The island of Atooi, in shady woods, near Kolao. A perennial plant with prostrate or trailing 

 branches, extending over two or three feet of surface. The whole plant sparingly strigose, green. 

 Leaves petiolate, deeply bipinnately dissected, the segments simple, cuneate-oblong, or two or 

 three-lobed, the rachis set with small simple segments. Flowers small and very inconspicuous, 

 terminal, on very short pedicels. Involucrum strigose, the leaves foliaceous, lanceolate, acute, 

 . very few, but imbricated, scarcely distinguishable from the paleae of the receptacle. Rays two or 

 three, pale yellow, oval, scarcely as long as the involucrum, with a smooth exserted style and 

 stigma, and, as well as the florets of the disk, possessing a distinct tube. Anthers dark brown; teeth of 

 the florets reflected. Achenium truncated and pubescent at the summit, the angles tubercular, 

 the base also obtuse; tabescent achenia linear-obovate, also somewhat tubercular and quadrangular. 

 Considerably allied to the preceding genus, but very distinct in habit, and almost wholly divested 

 of pappus.
