54. SyRRHEONEMA. 
This genus was proposed by me for a climbing plant having 
roundish cordate leaves, with a supra-axillary inflorescence, 
consisting of from three to six short fasciculated peduncles 
bearing generally three sessile flowers, which are small, with 
six tomentose imbricated sepals, no petals, and three stamens 
united for half their length into a central column%, the free 
portions being nearly erect, fleshy, and semiterete, each having 
four distinct anther-lobes quadrately disposed and imbedded 
introrsely in their summits. There is some resemblance in this 
latter feature to the stamens of Jateorhiza; but the analogy 
extends no further. 
The genus approaches Detandra, Aristega, and Desmonema in 
having three monadelphous stamens; but it differs from them 
in having no petals and in other particulars. In its inflorescence 
(consisting of several fasciculated, axillary, simple peduncles) it 
offers some analogy with Pycnarrhena and Antitaxis; but there 
the peduncles are 1-flowered, while here they bear from three to 
six crowded, sessile, very small flowers.
