island of Juan Fernandez. Their leaves are opposite or often er 

 alternate, especially at the top of the plant, sometimes entire, some- 

 times dentate or pinnatiiid, accompanied by two small caducous 

 stipules ; often replaced by bracts at the summit of the branches. 

 The result is that the flowers/ axillary to a certain point, may above 

 form a spike or terminal cluster. In the axil of each leaf or bract 

 is either a solitary flower, with or without lateral bracts, or a cyme, 

 or a few-flowered glomerule ; the pedicels, when present, are short 

 and often pendant. 



Meionedes ^ and Loudonia are very near Haloragisj and should 

 not be separated from it. The former is Haloragis on a dual-^ type,

that is with two sepals, two petals, two verticils of two stamens, and 

 an ovary with two uniovulate cells. M. Brownii, the only species 

 known,'^ herbaceous and glabrous, grows in South Australia and 

 Tasmania. Loudonia^ (fig. 462-464), native of the same countries, 

 has dimerous or tetramerous and 4-8-androus flowers, and the 4- 

 winged ovary has two or four cells, the separating partition of which 

 disappears more or less completely at a certain age and is represented
