1. DICHONDRA, Forst. 



Small prostrate or creeping- herbs with roundish stalked leaves and 

 solitary inconspicuous axillary flowers. Sepals nearly free. Corolla 

 broadly campanulate, shorter than the calyx, deeply 5-lobed, almost 

 valvate. Ovary very deeply 2-lobed or almost apocarpous, each lobe 

 2-celled. Styles 2 from between the lobes, stigmas capitate. Fruit 

 usually of two indehiscent or irregularly dehiscent nutlets. Seeds- 

 roundish, smooth. 



A genus very close to the Boraginacea?, but distinguishable from the radicle 

 directed to the inferior micropyle, bj- tlie plicate and curved embryo. The habit 

 and indumentum and shape of leaves are also rather those of the Convohmlacefe.
