The order SanTaLace#, named from Santalum, the genus which 
supplies the fragrant sandal-wood of the East, has with us but one 
genus, Comandra Nutt. 
Calyx bell-shaped, becoming urn-shaped; lined above the ovary with an adherent disk,

Fruit drupe-like or nut-like, the tips of the persistent sepals forming a crown, the cavity 
filled by the globular seed. Low and smooth perennials, with herbaceous stems from a 
somewhat woody base or root, alternate sessile leaves, and greenish-white flowers in small 
umbel-like clusters.
