466 PATAGONIAN EXPEDITIONS ! BOTANY. 



at first pendulous, elongate and usually erect in fruit. Pedicels short; 

 bracts ligulate, as long as the flowers. Calyx-lobes obtuse. Petals small, 

 reflexed at apex. Berries red, agreeable. ("Fruit black," Speg.) 



Patagon., by Lago Nahuel-huapi ; Punta Arenas (J. B. Hatcher) ; over 

 all Fuegia to Cape Horn. In Chubut a variety with smaller leaves, sub- 

 hastate triangular. (Speg.) 



Family 50. CUNONIACE^:. 



Shrubs or trees, with opposite or whorled stipulate leaves and small 

 flowers in. heads or racemes; the flowers mostly perfect, with a hypogy- 

 nous disk, and 5- rarely 4-merous calyx and corolla; stamens mostly 

 twice as many and perigynous, on a disk. Carpels few, mostly 2. Fruit 

 usually a 2-lobed capsule. Seeds numerous, in 2 ranks, sometimes hairy 

 or winged. Embryo small, in large endosperm. 



Species 120, chiefly in the Southern hemisphere. Weinmannia and 

 its relatives, having woolly seeds which are carried in birds' feathers, are 

 widely dispersed in places south of the equator. , The others are confined 

 to a narrow region ; as New Caledonia, and E. Australia. The Brazilian 

 genus Belangera is closely allied to the Malay-Caledonian Geissois (Engler). 

 In this last case the migration must have been toward Brazil.
