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.
