island of Juan Fernandez. Their leaves are opposite or of'tener 

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

 times dentate or pinnatifid, 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. 



Meionectes ^ and Loudonia are very near Raloragis, and should

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^ (flg. 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
