Proteaceae. A genus of about fifty species of handsome 

 greenhouse evergreen shrubs, allied to Bankna, from 

 which genus it is readily distinguished by the involucre, 

 by the flat, or nearly flat, receptacle, and by the fruit. 

 All are confined to Western extra - tropical Australia. 

 They are very rarely seen in cultivation, notwithstanding 

 their great beauty. For culture, see ~ ~ '

 and inflorescence, but may be distinguished from ** mudm 

 by the glabrous perianth limb. Young branches usually tomen- 

 tose and hirsute, with spreading hairs. A. 4ft. to 5ft. Svx.

 of species of elegant dwarf hardy shrubby plants, natives 

 of cold and Arctic regions of the Northern hemisphere. 

 Flowers white or yellow, large. Leaves simple, petiolate, 

 oblong, entire, crenate or snb-pinnatifid ; margins recurved, 

 shining above, downy beneath. They are of easy culture 

 in a moist peat soil. Propagated by cuttings, by divisions, 

 or from seed.

 phytal on branches of trees). OBD. Orchidece. A 

 which contains so far as is at present known only the 

 species described below. It is one of the smallest and 

 most curious of Orchids, and, until it flowered at Kew in 

 1871, was only known by a drawing made by Griffiths 

 in the Malayan Peninsula, in 1835. It grows in a warm 

 house, on pieces of hard wood to which the bark remains 

 attached.

 sepals yellow-green, with dull purple bands forming wings at the 

 apex of a long, curved, green, purple-spotted stipe, which projects

 slender ringed trunks, natives of New Guinea, tropical 

 Australia, and the Pacific Islands. Flowers monoecious, 

 in branched panicles; spadices springing from the trunk 

 below the crown of leaves. Leaves terminal, regularly
