 erect, 1^ in. long, the outer ones shorter, narrow, and spreading. 



In the Happy Valley, festooning the trees, more rare on rocks on Mount Gough, Cham-

 ■to .5, inserted on the outside of a hypogynous disk, slightly imbricate in the

 side the disk. Filaments often flattened, and sometimes united at the base. 

 Anthers versatile. Ovary entire, of 1 or more cells, with 1, 2, or more, usually 

 •pendulous ovules in each. Style simple, with an entire or slightly lobed
